The Display panel

The Display panel controls the waveform and spectrogram settings. You can show or hide additional settings using the dropdown menu at the top right of the panel.

Choose View > Panels > Display to show or hide the Display panel.

Icon	Item	Description
	Color Mapping	When the composite view is enabled (previewing all layers mixed), you can choose between several color maps.
	Amplitude	Drag the Min and Max sliders to define the amplitude range displayed.
	Brightness Curve (Pro only)	Drag the slider to adjust the brightness curve of the spectral display. Brightness curve is defined as log2(gamma)+1.
	Selection Opacity	Drag the slider to adjust the opacity of the selection.
	FFT Window (Pro only)	Choose the window type used for analysis. The window type is related to the dynamic range of the analysis. We recommend using Blackman-Harris for most applications.
	FFT Size	Define the size (in samples) of the spectral analysis. Higher numbers produce increased frequency resolution at the expense of lower time resolution and longer computational time.
	Resolution (Pro only)	Resolution increases the time and frequency overlapping of the spectrogram. Sharpness increase the sharpness based on the resolution defined by the first parameter.
	Wave Range	Define the displayed wave range (lowest, range, highest).
	Time Range	Define the displayed time range (start, length, end).
	Frequency Range	Define the displayed frequency range (bottom, range, top).
	3D Range	Define the displayed 3D range (horizontal (X) and vertical (Y)).

The History panel

The History panel allows you to see a list of the actions you've performed.

Choose View > Panels > History to show or hide the History panel.

The last action is always displayed at the bottom of the list.

Click an action to step through your edit history and undo/redo actions.

The icons at the bottom of the panel allows you to undo, redo, duplicate the current state into a new project, and delete the selected action (and the followings).

The Channels panel

The Channels Panel allows you to enable channels in multichannel audio files.

Choose View > Panels > Channels to show or hide the History Panel.

When you select a specific channel, only this channel can be modified.

Note: Click a blank area of the Channels panel to select all channels again, or click and drag the mouse over all channels, or click the Select All Channels button at the bottom of the panel.

If you want to exclude channels from playback, select the Mute button . To unmute a channel, click the Mute button again to deselect it.

Note: Muted channels are not displayed in the spectral display and are excluded when selecting data. For more information, see Selecting spectral data

Click the Solo button to mute all unsoloed channels. Click the Solo button on additional channels to add them to the solo group.

To remove a channel from the solo group, click its Solo button again.

Note: If the Mute and Solo buttons are selected for a channel, the channel will be played during playback.

The icons at the bottom of the panel allows you to select all channels, resample the project, and reinterpret the project.

The Layers panel

The Layers panel allows you to manage the layers and layer groups in your project. You can mute/unmute or solo/unsolo layers, change phase, adjust volume, duplicate, delete, move, group and merge layers.

Choose View > Panels > Layers to show or hide the Layers panel

Selecting a layer or group

Click a layer or group to select it. To deselect a layer hold Ctrl (Windows) or Command (Mac) while clicking it.

A bold line in the overview bar represents the selected layer. For more information, see Waveform Display and overview bar

Changing the color of a layer or group

Click the color indicator to set the color that will be used to display a layer in the spectral display, waveform display and overview bar.

When working with layer groups, the group color is used for all the group's layers.

Muting and soloing a layer or group

Muting layers or groups: Click the Mute button to prevent a layer or group from being played in the mix. Click the Mute button on additional layers or groups to add them to the mute group.

To unmute a layer or a group, click the Mute button again.

A dimmed line in the overview bar represents a muted layer or group. For more information, see Waveform Display and overview bar

Soloing layers or groups: Click the Solo button to mute all unsoloed layers or groups. Click the Solo button on additional layers or groups to add them to the solo group.

To remove a layer or group from the solo group, click its Solo button again.

Note: If the Mute and Solo buttons are selected for a layer or a group, the layer or group will be played during playback.

Changing a layer's phase

When you add a new layer, it's mixed with the other layers in your project.

Click the Phase button to switch between additive and subtractive mode.

A dotted line in the overview bar represents a phase-inverted layer. For more information, see Waveform Display and overview bar

Renaming a layer or group

The file name is used for the layer name by default. Perform either of the following actions to edit a layer's name:

Double-click the layer name in the Layers panel and type a new name.
Right-click (Windows) or Control-click (Mac) a layer and choose Rename from the shortcut menu. The Properties dialog displays information about the layer and allows you to specify a new name.

Adjusting layer volume

Drag a fader in the Layers panel to adjust a layer's volume in the global mix.

Note: Double-click the fader handle to reset the volume to 0 dB.

Adding a layer group

Layer groups help you to manage complex projects by grouping related layers. You can name, mute and solo, and expand/collapse layer groups. See also Grouping layers

Click the New Group button at the bottom of the Layers panel to create a new group. You can then drag layers within the layers panel to add then to groups or move them among groups.

Note: If you want to remove all layers from a group, select the group and choose Layer > Ungroup.

Adding a new layer

Click the New Layer button at the bottom of the Layers panel to add a new, blank layer to your SpectraLayers project.

If no layers have been created in the current project, you'll be prompted to set the sample rate, channels, and length in the Create New Layer dialog.

Duplicating a layer

Right-click (Windows) or Control-click (Mac) a layer and choose Duplicate from the shortcut menu. The new layer is added above the original layer in the Layers panel.

Note: You can duplicate a layer to another SpectraLayers project by choosing Layer > Duplicate To and then choosing a project.

Deleting a layer or a group

Right-click (Windows) or Control-click (Mac) a layer and choose Delete from the shortcut menu.

Rearranging layers

Drag layers in the Layers panel to rearrange them.

Merging layers

Right-click (Windows) or Control-click (Mac) a layer and choose Merge Down from the shortcut menu to merge the layer with the next layer in the list.

When a layer group is selected, choose Merge Group from the shortcut menu to merge the layers in the selected group to a single layer.

For more information, see Merging layers
