Overview
Antresol is a flanger type effect based on an authorial emulation of a discrete time delay line (BBD – Bucket Brigade Device) characterized by an ultra low aliasing level, inspired by a classic stomp box from the Mistress series.
After loading the plug-in to a host application the GUI appears:

Signal flow
This chapter describes the path of the signal's flow through the Antresol plug-in, presents the basic components of this effect unit and its control parameters.
Basic modules
In general, the plug-in structure can be described as a delay feedback loop with an adjustable value and a delay time controlled by a LFO (Low Frequency Oscillator) generator. In this general structure more detailed and additional functional blocks can be distinguished, which have their equivalents in the graphical interface sections.
Parameters of modules located before the feedback loop
Initially we have a set of parameters which influence the signal before passing it on the feedback loop:

Pre-Loop parameters
We can distinguish:
- Preamp – Preamplification of the signal in the range from 0 to 24 dB.
- M/S Mode – The choice of stereo representation of the processing signal. The switch is turned off by default, which results in processing in the L/R (Left/Right) domain. However, if we turn it on, the signal is processed in the M/S (Mid/Side) domain.
- Ch. X-Fade – Signal crosstalk control between stereo channels, depending on the representation. The parameter works as a double crossfader:

Ch. X-Fade in its full value range
When the value of the parameter is set to minimum (None), the crosstalk between channels does not occur, therefore the stereo signal is passed on to the loop in an unchanged form. Along with increasing the parameter value to the Clone position, a bigger portion of the Left (or M) channel signal is added to the Right (or S) channel signal or vice versa until reaching the Clone position, in which both channels contain the same signal. The input becomes monophonic because both channels have 50% L and 50% R each. Further increasing the value
of the parameter towards the Swap position (maximum value) means that a smaller and smaller portion of the original (input) Left channel is in the Left output channel (valid also for the Right channel) up to the point in which we have the Right channel signal in the Left channel and vice versa. Therefore, the channels are swapped.
This parameter is extremely useful for all types of monophonic signals' spatializations. In particular, while working in the M/S domain, in which component M can be duplicated in component S (in properly applied volume ratio), which on the other hand can be processed independently in subsequent stages of the processor's operation
Parameters of feedback loop modules
In this section a set of parameters is described, which are directly connected with controlling the work of the delay line with a feedback loop and external modules interacting with it.
BBD line emulation - True BBD

True BBD Section
The most important block of the entire effect is True BBD. It is actually the heart of the plug-in, as well as the code name for our authorial technique of emulating the discrete time delay line known from literature as BBD (Bucket Brigate Device) operating in the feedback loop. From the True BBD section on GUI we control the delay line's main configuration parameters. Before learning the function of each of the parameters let us familiarize with the BBD's operating principles:

BBD delay line's demonstrative scheme (buffer cells and timing clock)
The BBD delay line works like a buffer (FIFO structure; first in first out), to which the signal is passed on the input and after a while it emerges on the output.
BBD is defined as a discrete time delay line because it is composed of a definite series of cells (condensers), each of which stores / samples the current value of the signal. However, we cannot talk about sampling per se, because the signal's value is analogue and only the time is discretized.
The delay between the line's input and output is a result of the BBD's operating principle and not its construction. The entire circuit is pulse-clocked by an external timing signal. One clock tick means transferring the signal from cell N-1 to cell N, from N-2 to N-1 and so on, up to the last step, which is transferring the cell state from cell 1 to cell 2. The signal state from the delay line is saved to cell 1, meaning a single movement of the cell states by one position in the output direction.
The time intervals between subsequent ticks are finite small values, which is the reason why the delay occurs at all. The signal in the form of states is moving in finite time intervals through subsequent cells, from the first to cell N to finally reach the output.
Therefore, if we have, for example, 256 cells, the time needed for the signal to pass through the buffer is 256 clock ticks.
LFO
Basic parameters
The BBD delay line's time is controlled by a LFO generator, which output is passed on as a True BBD delay line's clock signal (after the conversion to a series of timing pulses). The LFO is controlled by the following parameters (top row).

LFO section on GUI
- Offset – The time offset between the undelayed signal (Dry) and the LFO oscillation's minimum.
- Rate – The rate of the LFO generator's oscillations in Hz (from 0.02 to 40 Hz)
- Depth – The depth of the LFO generator's oscillations. When the value of this parameter is 0, the delay is constant and it is defined only by the Offset parameter.
For a better understanding, the following picture illustrates the manner in which the LFO influences the delay line's time:

LFO controlling the delay time
If we imagine the delay line controlled by the LFO as a read head which moves across the signal as it would across a tape, then the LFO controls the acceleration of the head.
Dependence between Rate and Depth
Contrary to most of this type effects in Antresol the LFO's oscillations depth is indirectly dependent on their rate. Along with increasing the rate of oscillations their amplitude is relatively decreasing. This dependence makes the effect more musical and its reaction to changes of those two parameters is more natural (exactly as in the Mistress flanger).

Time-variant frequency response of white noise and LFO modulating the value of the BBD delay line with an increasing rate of oscillation
Tempo sync
The LFO in Antresol can optionally synchronize the frequency and phase of oscillation with the host application's tempo. The Tempo Sync parameter is used to activate this function:

Tempo Sync. parameter in the LFO section
The parameter can be set to one of the four available values
- Off – Synchronization is inactive and the LFO speed is controlled by the Rate parameter in absolute units; Hz ranging from 0.02 to 40.
Full - Synchronization is active and the rate of LFO's oscillations is equal to the rhythmical value of the note set by the Rate parameter. - Triplet – Synchronization is active and the rate of LFO oscillation is equal to the duration of the triplet note set by the Rate parameter.
- Dotted – Synchronization is active and the rate of LFO oscillation is equal to the rhythmical value of dotted note set by the Rate parameter.
When the synchronization is active the Rate parameter can be set to one of the following rhythmical values: 1, 2, 4, 8, 16 and 32 bars, half-note (1/2th), quarter-note (1/4th), quaver (1/8th), semiquaver (1/16th) and demisemiquaver (1/32th):

Bar division into smaller rhythmical values
The Triplet and the Dotted note are modifiers of the rhythmical value, which can be selected using the Tempo Sync. parameter. The Dotted note is 3/2 longer than a normal note, while a Triplet constitutes only 2/3 of its original rhythmical value.

Note length
Stereo Phase Shift
When Antresol is used on a stereophonic track, two independent delay lines operate implicitly controlled by two separate LFO generators (one per channel). Each of them independently processing Left and Right channel (or Mid and Side depending on the representation).
The Phase Shift parameter allows to control the relative phase shift of the LFO's oscillations between stereo channels:

Phase Shift Parameter
For 0 degrees value the LFOs will have the same phase for the Left and Right channel (they are going to be in the phase). By increasing the phase shift we achieve a pleasant effect of widening the stereo panorama. The shift can be increased up to the value of 180 degrees, during which the LFO generators operate in counterphase.

Phase Shift between generators for each stereo channel
Stereo Link
Internally, Antresol processes the stereo channels independently. Also the LFO generators can operate with different parameter values for each channel. Both generators are linked by default, operating with the same parameter values. With this setting it does not matter whether the LFO parameters are controlled by the knobs situated in the top row or in the bottom row (for Left or Right panel), since the indicator lights are visually paired (as columns).

Parameters controlling the left channel LFO work or the work of both chanells in link mode
Let us look at the Link diodes in the bottom part of the section:

Diodes controlling LFO parameter linking for Left and Right channel
They allow to unlink the chosen LFO parameters (Offset, Rate, Depth) in order to apply independent values per channel. If a diode under a particular parameter is turned off, we use the knobs in the top row to control the Left channel (or Mid) LFO parameters. From the bottom row we control the Right channel (or Side) LFO parameter.
BBD line configuration
The True BBD section controls the operating parameters of the delay line and allows to monitor the pulse frequency of the delay line's timing clock:

True BBD Section
Here we can distinguish:
- BBD Length – Delay line's buffer length (number of cells), which can have the following values: 16, 32, 64, 128, 256 and 512.

BBD Length parameter
- LFO to Clock Voltage Curve – The characteristics of converting the values generated by LFOs to series of impulses for the BBD line oscillator clock, which allow different dynamics of frequency response changes in time.

LFO to Clock Voltage Curve parameter
We have 3 different characteristics to choose from:
- Mistress – Characteristic transferred from the classic guitar flanger Mistress, which can be described as Convex. It results in higher dynamics of delay time changes for smaller values and lower dynamics for bigger delays, creating a characteristic image in spectrum changes:

Time-variant frequency response of white noise and LFO modifying the BBD line delay value with Mistress characteristic
- Linear – Linear characteristic – The conversion of the signal's value generated by the LFO to the clock's frequency has a linear image in the frequency response dynamics:

(repeated) for each row in the chart: Low, High, etc. The values are estimated based on the provided code.Time-variant frequency response of white noise and LFO modifying the BBD line delay value with linear characteristic
- Concave – Concave characteristic – The change dynamics is big for bigger delays and small for smaller values, which can be observed in the frequency response:

Time-variant frequency response of white noise and LFO modifying BBD line delays with concave characteristic
- Range – Parameter which readjusts the oscillator clock's frequency, at the same time modifying the range of delays generated by BBD line:

Range parameter
Knowing which parameters are used to control the LFO section and the True BBD line, let's see how the sections are connected on the signal flow level. The diagram below illustrates the manner in which the signal generated by LFO and the BBD delay line parameters influence each other:

Diagram of True BBD block connected to its controlling LFO
As we can observe, the LFO generator's output is connected to the Delinearize block, in which a proper transfer characteristic from the LFO to the BBD clock's frequency is applied. Subsequently, the output frequency is scaled with the Range parameter and passed on to the clock input of the delay line as a series of timing pulses.
While selecting delay line parameters the Freq display might be of help in the True BBD section:

BBD Frequency
It informs about the current frequency of the BBD's timing clock. This frequency is determined by many factors: Range parameter, LFO to Clock Voltage Curve, BBD Length and LFO section settings.
It is worth mentioning that for low frequency of timing pulses, below the sampling frequency, we can hear interesting sound effects, re sembling a signal's decimation, which of course are not an unexpected side effect. Exactly the same type of sound artifacts would appear in the original, which was an inspiration for Antresol if its internal parameters were properly readjusted in order to achieve a similar operating range of the BBD's timing clock. This is due to the fact that the innovative algorithm applied in Antresol operates on a quasi-analogue signal representation, precisely reflecting all the aspects of electronic circuits' operation and coappearing side effects.
Feedback value

Feedback section
This section's parameters control the feedback value of the delay loop. If the stereo channels are linked (Link flag on):

Feedback parameter's stereo link flag
The feedback is controlled for both channels simultaneously by using any of two potentiometers (they are visually linked). If we turn off the Link flag, the feedback value can be controlled independently for both stereo channels (L/R or M/S) by using both potentiometers.
The knob in 0 is the neutral position (no feedback). An inclination to the right increases positive feedback whereas an inclination to the left increases negative feedback.
Parameters of modules located after the feedback loop
This section describes modules which process the feedback loop's output signal.
Low Cut Filter
The Low Cut Filter allows to discard the excess amount of energy accumulated in the lower signal's register, which is cumulated during the passing of the signal through the feedback loop.

Low Cut filter
The filter can operate in one of three modes:
- Off – the filter is inactive delays
• Low – a passive filter is activated which cuts frequencies below 50 Hz - Mistress – a passive filter is activated which cuts frequencies below 100 Hz
FX section
This is the final block of this processor, in which the unprocessed signal is mixed with the processed one.

FX Section
The FX block can generally work in one of two modes:
- Manual
- Automatic
We select the work mode with a bistate button Mistress Auto Mix Mode

Mistress Auto Mix Mode parameter
Dry / Wet manual mixing
In this mode we manually set changes in the ratio between the processed and unprocessed signal using the following parameters:
- Gain L/M – Volume of the Left (Mid) Wet signal channel
- Gain R/S – Volume of the Right (Side) Wet signal channel
• FX – the ratio of mixing Wet and Dry signals
Dry / Wet automatic mixing - Mistress Mode
In this mode the unprocessed and processed signals are mixed together automatically and the ratio is applied on the basis of feedback loop parameters to achieve the best sound effect.
Setting Antresol to Mistress emulation mode
Antresol is inspired by the classic flanger type guitar effect from the Mistress series and the solutions applied in it constituted a strong in spiration for the functioning of our processor.
- Firstly, the automatic Dry and Wet signal mixing is activated with the Mistress Auto Mix Mode switch

Mistress Auto Mix
Mode parameter
Then, Dry and Wet signals are mixed together in a ratio arbitrarily set on the basis of the feedback loop parameters in order to achieve the best sound effect. Additionally, activating the automatic mixing mode activates also a special pre-filter (depicted on diagram Low Cut parameter) which limits the input signal on bands. The parameters of these filters are not controlled by any GUI parameters and are affixed on the value corresponding to an identical mode which can be found in the Mistress guitar pedal.
- Another element which allows to achieve an original Mistress sound is the high-pass filter located after the feedback loop and controlled by the Low Cut parameter on GUI.

Low Cut parameter
Set to Mistress, apart from removing low tones from the feedback loop's signal, it additionally activates a low tone reconstruction block during the automatic Dry and Wet signal mixing (Mistress Auto Mix Mode must be active).
Setting these values on the two aforementioned parameters causes the plug-in to act as an exact emulation of the classic Mistress guitar effect.
Working with the Mono tracks
If we use Antresol on a monophonic track, only the Left plug-in channel parameters are used to control the processing track. Additionally, some of the parameters do not work at all. Here is a list of all controllers, which functioning is changed when the plug-in is used on a mono track:
- MS / Mode switch – does not work. Due to processing of a monophonic signal we are unable to select a type of representation for the stereo signal.
• Link diodes from the LFO and Feedback sections do not work.
• LFO parameters from R/S row (for the Right channel) do not work. The LFO generator is controlled by the Left channel parameters only. - Feedback R/S parameter (for the Right channel) does not work. – The control is made by means of the Left channel Feedback parameter only.
- Gain R/S parameter (for the Right channel) in the FX section does not work. Only Gain L/M parameter is responsible for controlling the feedback loop output volume.

The input signal is passed on the optionally working (if auto-mix is activated) Mistress pre-fiter. Next, preamplification and optional representation shift from L/R to M/S occurs. In the subsequent step the signal is passed on to stereo channels' cross talk addition block. After wards it enters the feedback loop.
After leaving the feedback loop the signal goes through the Low Cut (Hi Pass) filter and subsequently it is passed on the mixing block with the unprocessed signal. This section is illustrated in more detail in picture 33 below.

Dry and Wet signals' mixing block in Antresol
The Diagram depicts the Dry and Wet signals' mixing block in Antresol, which is partially based on the Mistress guitar pedal construction. If the Auto Mix mode is active the signal goes through the Mistress Mode subsection. The Dry and Wet signal mixing ratio is set automatically on the basis of the Feedback parameter. Additionally, if we switch the Low Cut filter to Mistress position, the reconstruction block of the low signal frequency from the feedback loop is activated (Bass Recovery).
Preset Management
Preset storage
Presets, both from Factory content and user ones, are stored as files in proper locations on the disc. Each time a plug-in instance is loaded into a project, these locations are scanned and the presets found there are consolidated into a single linear structure (list) in the Preset Browser.
Browsing presets
The Preset management section (no matter what kind of preset it concerns) enables quick navigation and browsing of the preset structure:

The Preset management section
- PRESET - Displays the name of the currently loaded preset. Clicking the display opens the Preset Browser panel, allowing you to browse factory / user presets.
• Prev / Next - Hovering over right side of the Preset display exposes the Prev / Next buttons: They allow for linear browsing of the presets list (depending on currently set filters - see sections below). - Save ▶ - Saves current parameters as a new preset or allows for overwriting of the existing one (see sections below).
Right-clicking over the Preset display opens a context menu with two or three additional options:
- Init - Restores initial settings of plug-in parameters.
- Reload - Reloads the most recently loaded preset.
- Save - Seedescription above.
The Preset Browser looks as follows:

The Preset Browser
There are four main parts:
- Sources - Situated in the left column, filter content Sources for displayed presets.
• Filter - Below Sources, a preset Filter that uses the Tags system.
• Results - List of presets (shown in the middle column) from Sources that meet criteria set in the Filter.
• Info pane - The right column shows information about the currently selected preset(s), divided into several subsections.
If available - For some preset types this button can be hidden and accessible from the contextual menu (accessible via right mouse-click on Preset display)
If available
Sources
In this section, you can choose a Source / Source(s) that you want to browse presets from.

Preset Sources
There are two resources to choose from:
- Factory - Delivered together with the plug-in and cannot be modified (read-only).
- User - Created by the user and can be freely modified or shared with other users.
Choosing any of them will cause the results to narrow to the presets from one resource.
Filter
The section below is the Filter, which represents a preset filtering system using Groups and Tags to browse the content.

The Filter section
Groups and tags
Each Preset is described by a few common Groups. Within each of them there may be one or more Tags from a particular set.

The Filter group
Presets from the Factory resource were assigned Groups and Tags when they were created.
Groups and Tags describe the content clearly, taking into account the plug-in's purpose.
Editing of the Groups and Tags for Factory content is limited. User presets can be described with the same Groups and Tags as Factory content, or you may define additional Tags within factory Groups and even create your own Groups with your own Tags to describe your own presets.
The only limitation is that a user cannot remove factory Groups or Tags from Factory content.
Results
This is a list of presets from chosen Sources that meet the filtering criteria. The basic function of this section is to browse and load presets. It can also be used for editing, which is described later.

Preset filtering using Groups and Tags
The Filter section contains Groups of Tags. Each Group is represented by a rectangle with the Group name + set of Tags inside.

Group 2 with two tags set (Tag 2 and Tag 3)
The filtering process cascades from top to bottom. This means that all presets available in the selected Sources are filtered by selected Tags from the first Group (uppermost one), then the Group below and so on, until filtered by the last active Group (the bottom one).

Preset Filtering with the use of Groups
The result of the cascade filtering process is listed in the middle column, the Results / presets list section. You can also consider the Results list as an intersection of preset sets, found by filtering through every individual Group.
Basic Actions
Tags work as toggle buttons. Click to activate / deactivate a Tag; a gray background color means that the Tag is inactive, and orange means that the Tag is active.

Group 2 with two tags set (Tag 2 and Tag 3)
If at least one Tag in a Group is active, then the Group (filter) also becomes active, otherwise the Group chosen doesn't affect the filtering process at all.
Group operator
When a single Tag is active in a Group, only presets having that Tag set are displayed in the Results.
If two or more Tags in a Group are active, the Results depend on the Operator chosen for the Group:

A Group operator
The Operator button works in toggle mode and offers a choice of two alternative Operators for the Group:
- Any ▶ - Means that a preset is shown in the Results when the preset includes at least one of the active Tags from the Group.
• All ▶ - Means that a preset is shown in the Results only when the preset includes all active Tags from the Group.
Filter enable / disable
You can quickly enable / disable the Filter using the toggle switch in the top-most section of the Filter:

An On/Off switch for a Group Filter
Other types of filtering
Searching by name
Alternatively, you can look for a preset by entering its name or just a piece of its name into the Find preset field:

The Find preset input
The Results are refreshed on-the-fly and they work together with the other filters.
Using the X icon clears the entire field:

Filtering Favorite presets
You can mark presets as a Favorite by clicking the Heart icon while hovering on preset name ▶. You can unmark presets by clicking the icon again (toggle mode):

Setting a preset as a Favorite on the list
Logical OR between Tags in the Group
Logical AND between Tags in the Group
It's allowed for every source (factory or user)
The flag is stored globally, meaning that a Favorite preset will be accessible as such from every other instance of the plug-in ▶
Once you have your Favorite presets flagged, you can quickly filter them using the toggle button with a Heart icon on it:
Find preset ...



Favorite presets filtering
If the button is active, then only Favorite presets will be shown (considering all remaining filters).
Filtering Pinned presets
You can Pin one or more presets using the Pin icon while hovering over a preset name ▶. You can unpin a preset by clicking the icon again (toggle mode):
Preset 6

Pinning a preset on the list
Unlike Favorites, this flag works locally and it's stored with the project file (not global config), so Pins are stored individually for every instance (with total recall, so a plug-in state is recalled if saved in the context of a project).
But, similarly to Favorites, you can easily filter presets using the toggle button with the Pin symbol on it:
Find preset ...


Pinned presets filtering
If the button is active, then only Pinned presets will be shown (considering all remaining filters).
Info pane
The column to the right shows information about the selected preset or presets. It also provides access to some of the preset editing functions.

The Info pane
There's a preset name at the top.

The Preset name in the Info pane
Additionally, if you've selected more than one preset there's information about how many more have been selected:

Selecting more than one preset
Below the preset(s) name there are few common sections describing selected presets:
- Tags
• Author - Description

Editing presets
You can perform certain actions on presets, such as adjusting Groups and Tags, deletion, renaming the presets as well as their export or import. One should bear in mind, however, that some operations are only allowed on user presets but not on Factory content.
Preset selection for Edit
Some operations can be done on more than one preset, so you're allowed to select more than one preset at once; in the Results section, you can choose a preset or a set of presets in the following ways:
- Click a preset - Selects (and loads) one preset from the list.
- Win ( Ctrl + Click the preset ), Mac ( Cmd + Click the preset ) - Adds another preset to an already chosen preset or a set of presets.
- Shift + Click the preset - Selects a range of presets from the last chosen preset to the preset clicked with the Shift key.
• Right-Click on any Preset in the Results section and choose the Select All option - this selects all presets:

Tags editing
When you select a preset or presets to change their tags, click the Pencil button next the Tags section in the Info pane to enter Edit mode for the Tags:

Entering the Tag edit mode
With the Edit mode enabled, you will see all possible Groups and Tags available for the preset(s):

The Tag Edit mode
Tag buttons work in toggle mode, much like filtering. Clicking them either sets or erases a Tag for a chosen preset. If a Tag is set for a preset, it is indicated by an orange background color, whereas if a Tag is not set, it has a gray background color.
If you choose multiple presets with existing tags, Tag buttons will appear orange if a specific Tag appears in all selected presets, and gray if it appears in none.
When a specific Tag is set only for a few of the selected presets, it appears as half-gray and half-orange.

Tags appearing only in part of selection
Changing the Tag status for one or more chosen presets sets or erases this Tag in all these presets. A status change is signaled by an Asterisk to the left of a Tag.

A Tag with a status change
Tag buttons highlighted in half-gray and half-orange color (where Tag values across the highlighted presets aren't all the same) work in a three-state system when switching between states; they turn gray if you erase the Tag for all selected presets, orange if you set the Tag for all selected presets, and return to half-gray and half-orange if the selected items remain unchanged or are returned to their initial state.
Potential changes have to be confirmed using the OK / Cancel buttons at the top part of the Tags section:

Confirmation buttons in the Tags section
Author editing
When you select a preset or presets to change the Author, click the Pencil button next the Author section in the Info pane to enter the Edit mode for the Author field:
