New features in SpectraLayers One 7.0.0

More New Features

Transform Tool

  • The Transform tool now allows you to duplicate a layer or selection content while moving and rescaling, and preserve formant and loudness while pitching up and down. See Transform.

Transform Selection Tool

  • The Transform Selection Tool is a new tool, which allows you to move and rescale selections without touching the content. It can be found under the Transform tool. See Transform Selection.

Playback Tool

  • The Playback tool now allows you to play a specific frequency range directly by clicking the spectrogram, or ignoring the current selection. See Playback.


  • Those edit actions now have more variations, making it very efficient to transfer data from one layer to another, without leaving the layer you’re working on. See Transferring Content Between Layers.


  • The Healing edit action is now AI powered, resulting in faster and more accurate estimation of the parts to reconstruct. See Removing Content.

Selection Loading

  • When loading a previously saved selection, you can now choose to Replace, Add to, Subtract from, Intersect with the current selection. See Loading and Saving Selections.

ARA Improvements

Unified Playback Behavior

  • The space bar (or DAW transport controls) now also plays spectral selection when one exist (you no longer need to specifically use SpectraLayers’ Playback tool for that).

Layer Panel Simplification

  • By default, the Layer Panel no longer display the external ARA groups (which correspond to the DAW tracks).

Layer Creation & Destruction

  • You can now create internal layers and groups.

More Improvements

Customizable UI Brightness

  • Customize the overall brightness of the UI.

VU Meter

  • Monitor output audio level while playing or recording.

Spectral Playhead

  • The playhead now highlight what spectral content is being played (for instance if a selection exist, or if using the improved Playback tool and playing only a specific frequency range or ignoring a selection).

Selection Area Numeric Fields

  • You can now visualize and edit numerically the boundaries of your selection.

Export Individual Layers

  • You can now export the active layer (in addition to the whole mix).

Quickly Toggle Between Sub-Tools

  • Repeat the keyboard shortcut for a tool category to toggle between each sub-tools of this category (for instance, T for the Transform tools will toggle between Transform and Transform Selection).

Avoid Unintended Selections

  • A four-pixel drag is now required to incept a selection, resulting in less unintended selections.

Easily Mute or Solo a Single Layer

  • Hold down Ctrl (Windows) Cmd (macOS) to limit soloing and muting to one layer or group at a time.

Prevent Unwanted Scrolling During Playback

  • When the project is currently playing, if a tool is actively in use (mouse button pressed), auto-scrolling is temporarily disabled.

Composite Mode is also reflected in the Layers Panel

  • When the Composite Mode is activated in the Display Panel, the layer colors shown in the Layers Panel slightly fade to white to emphasize that the spectrum is now displaying a mix of all layers.

Switch to Display Waveform and Spectral View Equally

  • The mini triangle switch to enlarge the waveform and spectral display now has an additional step so that you can easily display the waveform and spectral view equally.

Selection Visually Faded in Non-Active Channels

  • When channels are non-active, selections in these channels is half-faded.
