How can I integrate SpectraLayers with my DAW?

SpectraLayers supports ARA2 for tight integration with compatible DAWs (e.g., Cubase 10.0.30+, Nuendo 10.1+, Studio One 4.1+, Reaper 5.978+). It also works as an external editor with many DAWs including Ableton Live, Pro Tools (via AudioSuite), Logic Pro, FL Studio, and more. See the manual section 11.2 for detailed setup.

Does SpectraLayers Elements 6 support noise reduction?

Yes, Elements 6 includes a noise reduction process (section 9.6). You can select spectral data containing noise and apply reduction. Note that reverb reduction is only available in the Pro version.

What are the key new features in version 6?

Version 6.0 introduces ARA2 integration, a reworked interface, a new Advanced Selection System, a new Move tool, Master Mute and Solo in Layers and Channels panels, Target Active Layer Color switch, and improved Frequency and Harmonics selection tracking.

How do I select specific frequencies in the spectrogram?

Use the Frequency Selection tool (Pro only, but Elements includes basic selection). You can also use the Marquee Selection, Selection Brush, or Magic Wand. Hold Shift to add to selection, Alt to remove. Adjust settings like Fade, Thickness, and Tracking Limit in the Tool Settings toolbar.

Can I work with layers nondestructively?

Yes, SpectraLayers uses a layer system for nondestructive editing. You can cut/copy data to new layers, invert phase to subtract, mute/solo layers, and adjust volume. Merging layers consolidates changes; saving as .slp project preserves all layers.

What audio file formats can I open and export?

You can open WAV, AIFF, FLAC, MP3, Ogg Vorbis, and more. Export supports WAV, AIFF, FLAC, MP3, and Ogg Vorbis. The project file format is .slp, which saves all layers and settings.

Is there a way to recover unsaved work after a crash?

Yes, SpectraLayers saves temporary recovery files. You can set the session path and maximum recovery days in Preferences > System. On restart, the software attempts to recover the last session.

How can I customize keyboard shortcuts?

Go to Edit > Preferences (Windows) or SpectraLayers > Preferences (Mac), then the Shortcuts tab. You can filter, click a shortcut to change it, clear, or reset all to defaults. Presets can be saved and loaded.

Does SpectraLayers Elements 6 support multichannel audio?

Introduction

Spectral...

In most audio applications, audio is displayed as a waveform that represents audio in the time domain (amplitude vs. time):

This representation shows the global power of sound; however it doesn't show what's inside the sound.

Spectral data represents sound in the frequency domain. You can think of it like a musical score: the higher the peaks, the higher the tones; the stronger the peaks, the stronger the tones. Everything can be analyzed with this representation: music, voice, even noise.

Spectral analysis uses discrete FFT sampling: you have to choose between time and frequency accuracy. A FFT Size of 2048 or 4096 is usually good for most situations (with a file sampled at 44,100 Hz or 48,000 Hz). Feel free to change the size on the fly as the accuracy of your work highly depends on it.

You should also play with the multiplier and gamma settings to see the small peak details in the spectral view.

...Layers

The layer system allows you to refine your work extensively in a nondestructive way, thanks to the additive and subtractive nature of layer mixing.

If you cut and paste data from one layer to a different layer, you add the layers nondestructively: the sum of the two layers is identical to the source data, but you have full control over the mute/volume state of the data you extracted to that new layer.

If you copy and paste data from one layer to a different layer, and then invert the phase of that new layer, you subtract the layers nondestructively: the first layer still contain all the original data, and the new, inverted layer acts to subtract the original data. When this negative layer is muted, you get your original data back. The volume of this inverted layer controls how much you want to mask from the original data.

Processes and Tools

Processes work the same way they do in usual audio applications: you select an area, and the process is applied to the whole area. For more information, see Processing spectral data

The difference with SpectraLayers is that you can select not only time but also frequency areas, so the process is only applied to a certain range of frequencies.

The processes are also different by nature, because they are designed to use spectral data instead of raw audio data, so the purpose and range is not the same as usual audio processes.

Tools work the same way they do in paint applications: they are local to the mouse position and allow you to work on specific frequencies. For more information, see The Tools toolbar

• Navigation tools allows the user to navigate the spectrogram.
• Transform tools allows the user to shift layers in time or to rescale them.
• Measure tools give the user specific information about spectral data. For more information, see Measuring spectral data
• Selection tools allow the user to select spectral data. For more information, see Selecting spectral data
• Modification tools allow the user to retouch spectral data. For more information, see Modifying spectral data
• Draw tools generate spectral data from scratch. For more information, see Drawing a frequency

Getting Started

Beneath its streamlined interface, SpectraLayers provides you with powerful tools for spectral editing. This topic will help you find your way around SpectraLayers so you can unlock its full potential.

1. When you first start SpectraLayers, the tools are unavailable until you open a file or create a project.

1. We'll create a project by open an existing audio file.

Click the Open button (or choose File > Open) to create a project from an audio file. After you click Open, you'll browse to the file that you want to be the first layer of your SpectraLayers project.

After you open the file, you'll see it displayed and highlighted in the Layers panel in the bottom-right corner of the SpectraLayers workspace.

The tools are now available on the left side of the SpectraLayers workspace. For more information, see The Tools toolbar

In the center of the screen is the spectral display. In the spectral display, the horizontal axis represents time, and the vertical axis represents frequency. The spots you can see correspond to a mix of the various frequencies and noise that compose your audio file. The higher the spots, the higher the pitch of sounds in your audio file. For more information, see Spectral Display

You can play your audio file by clicking the Play button ▶ or pressing the space bar.

1. Before performing any edits, you need to select a layer.

Click the layer in the Layers panel to select it if it isn't already selected. A selected layer is highlighted in the Layers panel.

1. Now let's modify the spectrogram.

After you select a layer, the tools in the Tools toolbar are available. The Retouch tools act directly on the layer you selected.

Select the Eraser tool and click and drag in the bottom of the spectral display to erase data in the lower frequencies of your audio file. For more information, see Erasing spectral data

Now play your audio file, and notice how the sound is different — you've done your first spectral editing.

1. The first step in most editing is selecting data in the spectrogram. Let's create some selections.

Let's take a closer look at some frequencies. If your file contains vocals or musical instruments, you'll see horizontal lines that represent syllables or musical notes. Several of these lines on top of each other represent harmonics, and they create the audio signature of each voice and instrument.

Green glowing vertical lines against a dark background, no text or symbols visible

1. Zoom the spectral display to find the parts of a spectrogram that you want to edit.

Use the Zoom tool at the top of the tools bar on the left to change the magnification of the spectral display.

You can navigate the spectral display using the Hand tool next to the Zoom tool. Drag with the Hand tool to move the spectrogram within the spectral display.

When you zoom in horizontally or vertically, you may notice that the frequencies will appear blurry:

Abstract green glowing pattern with horizontal streaks on dark background (no text or symbols)

The FFT Size control in the Spectral Settings toolbar allows you to refine the spectral display. You can choose a different resolution by dragging the slider or typing a value in the edit box.

After increasing the frequency resolution, you can see that the frequency lines are thinner.

Green glowing pattern with horizontal striations against a dark background (no text or symbols)

Experiment with different FFT sizes to find the setting that allows you to see each line clearly.

1. Let's select frequencies so we can cut them and paste them to a new layer.

Click the Frequency Selection tool “” in the Tools toolbar. Move your mouse around the spectral display and see how the tool snaps to the different frequencies in the spectral display: the frequency under the tool is highlighted:

Green glowing pattern with horizontal striations, no visible text or symbols

With the Add to Selection button in the Tool Settings toolbar selected (or by holding the Shift key), click a few frequencies on top of each others, and see how they are also highlighted. It means they have been added to the selection. Notice the regular Play button ▶ (or space bar) now plays the current selection.

Green glowing pattern with horizontal striations and a bright spot, no text or symbols visible

1. Let's cut the selected frequencies. Choose Edit > Cut or press the Ctrl+X (Windows) or Command_X (Mac). Notice that the frequencies you selected in the previous step are removed from the spectral display.

Green glowing abstract pattern with horizontal striations and vertical bands (no text or symbols)

Play your project again. If you extract enough data, you can completely remove voices, instruments, or any sound from your audio.

Don't hesitate to create several layers and experiment with the different tools. You can even adjust the FFT size setting in the middle of an extraction if needed!

1. Finally, let's paste the contents of the clipboard to a new layer:

a. Click the New Layer button 🎨 (or choose Layer > New) to create a new layer.
b. Click the new layer in the Layers panel to select it.

c. Choose Edit > Paste or press Ctrl+V (on Windows) or Cmd+V (on Mac). Notice the spectral color of that layer match its color setting in the Layers panel.

Green-tinted abstract pattern with horizontal striations and a blue gradient overlay (no text or symbols)

1. Click the Mute button on the new layer or drag its volume fader to the left to reduce its volume. Notice the content fades away from the spectrogram as well. If you play your project, the frequencies you pasted to the new layer will be removed or attenuated.

6.13 Editing with ARA

If your DAW is ARA2-capable, you can use SpectraLayers as an ARA plugin. This allows a very tight integration between the host and the plugin: every region you send to SpectraLayers appears as a layer and remains synchronized with the host. If you move it or resize it in the host, the corresponding layer in SpectraLayers will be moved and resized as well. Every audio modification you do in SpectraLayers is automatically transferred to the host during playback or rendering, and saved with your host project.

The ARA protocol requires a 1:1 synchronization between the regions in the plugins and the regions in the host. For this reason, you cannot create or destroy layers within SpectraLayers in ARA mode. If you need more layers in SpectraLayers, your need to send more regions from your host to the plugin.

Viewing and selecting spectral data

Frequency, harmonics, and noise

In a spectral view, all sound is represented as a sum of frequencies with different amplitudes and phase. So if you record a pure tone (such as A4, 440Hz), you will see a straight horizontal line in the spectrogram at frequency 440 Hz. However, pure tones are typically generated by electronic devices or very specific instruments.

A red horizontal bar centered on a black background, with no visible text or symbols.

Figure 7.1 440 Hz sine wave

Voice and musical instruments are (mostly) composed of harmonics: several pure tones with different amplitudes and different frequencies. These frequencies follow physical rules: they are a multiple of the base frequency. If a piano plays A4, you will have a tone at 440 Hz plus a tone at 440x2=880 Hz with a different amplitude, plus a tone at 440x3=1320 Hz, etc.

Finally, noise is everything that cannot be described as pure tones. In the spectrogram, noise appears as clouds of random dots across time and frequencies.

Voice data

Voice is mostly harmonics because all vowels sounds use pure tones ("a", "e", etc). However, most consonants ("t", "k", etc) are noise. So when you select a full word you have to deal both with harmonic and noise sounds.

Figure 7.2 A voiceover recording

Instruments

- Classic instruments such as the piano, violin, trumpet, etc produce harmonic sounds.

Figure 7.3 A recorded saxophone

• Some synthetic instruments may produce unharmonic sounds (harmonic-like, but with float frequency multiplier).
• Percussive instruments such as drums produce noise.

Figure 7.4 A drum fill

Sounds from nature and engine sounds

• The sea and the wind are noise.
- Something that breaks or crashes is noise.
• Engine sounds can be noise or harmonics.

Moving and scaling harmonics vertically

While moving or scaling noise or pure tones does not change their nature, moving harmonics breaks the harmonic rules.

Moving harmonics adds a constant frequency: if a piano plays A4 (see above) and we move this sound by 100 Hz, the 3 first frequencies will be 440+100=540 Hz, 880+100=980 Hz and 1320+100=1420 Hz.

1420 Hz and 980 Hz are not multiples of 540 Hz, which means the sound will be unharmonic (it will not sound like a piano note anymore).

To preserve the harmonics, we need to scale (multiply) the frequencies. Scaling A4 by 1.2 produces 440 × 1.2 = 528 Hz, 880 Hz × 1.2 = 1056 Hz , 1320 × 1.2 = 1584 Hz .

1584 Hz=528 Hz x 3 and 1056 Hz=528 Hz x 2, so we preserved harmonics and the recording will still sound like a piano.

Formant and time envelope

The formant is the frequency signature of a sound, and it applies both to harmonic and noise sounds. It is the envelope of amplitudes across frequencies.

A person's voice sounds different from another person's voice and sounds different from a piano because the harmonics are different. If they all sing and play A4, they will all have the first 3 frequencies 440 Hz, 880 Hz and 1320 Hz (see above), but with different amplitudes each. This rule also applies to noise, where the random dots are shaped by different amplitudes.

Finally the time envelope also act a signature across time. Let's take a violin: it will sound very different drawing a bow across a string or plucking it, although the frequency envelope will be the same. The way amplitudes change over time is fully part of the signature of a sound whether the sound is harmonic or noise.

If you scale a sound too much (by a factor of 2 and above, or 1/2 and below), it will not sound exactly as played by the same source, because the formant and time envelope were scaled too.

6. Type values in the Horizontal Margin and Vertical Margin boxes (or use the spin controls) to control the time and frequency range that is used when casting peaks. Increasing the margin settings produces softer (feathered) peaks.
7. Type a value in the Strength box (or use the spin control) to set the gain that will be applied to the cast peaks.
8. Click OK to cast peaks with the current dialog settings.

To demonstrate the effect of casting with our bass guitar/kick drum example, let's start with a simple two-layer project. The following image shows the spectrogram of the bass guitar layer. This layer is displayed in red:

The following image shows the spectrogram of the kick drum:

The following image shows the mix of the kick drum and bass guitar. The bass guitar layer is displayed in red. The kick drum appears in the global mix and is displayed in green, You can see where the layers conflict:

After selecting the content of the bass guitar layer and casting peaks, you can see that the areas that conflicted with the kick drum have been removed:

Molding a layer

In spectral molding, the frequency content of the mold that shapes the selected layer, removing spectral data that exists outside the area of the mold in the same way a cookie cutter allows you to cut shapes from dough.

1. Load the layers you want to process. For more information, see Importing an audio file as a layer
2. Adjust the spectral display until the harmonics are clearly visible. For more information, see The Display panel
3. In the Layers panel, select the layer to which you want to cast peaks.
4. Choose Process > Imprint... to Layer. The Imprint dialog is displayed.
5. Select the Mold Operation. and the layer you want to use as the source for molding.
6. Type values in the Horizontal Margin and Vertical Margin boxes (or use the spin controls) to control the time and frequency range that is used when molding peaks. Increasing the margin settings produces softer (feathered) peaks.
7. Type a value in the Strength box (or use the spin control) to set the gain that will be applied to the cast peaks.
8. Click OK to mold peaks with the current dialog settings.

To demonstrate the effect of molding, let's start with a simple two-layer project with a music bed and a voiceover. The following image shows the global mix of the voiceover and a music bed. The music bed layer is displayed in red. The voiceover layer is displayed in green. You can see where the layers intersect:

After selecting the content of the music bed layer and molding peaks, the voiceover layer is used to mold the frequency content of the music bed. In the following image, you can see that mold of the voiceover layer has cut away portions of the music bed layer that do not intersect with the voiceover:
