Modifying spectral data

You can use the modify tools to manipulate spectral data in a layer.

Erasing spectral data

Erasing an area allows you to simply remove data from a layer.

1. Create a new SpectraLayers project or open an existing project file.

   For more information, see Creating a new project or Opening a project or an audio file

2. In the Layers Panel, click the layer that contains the data you want to erase.
3. Click the Eraser button . The cursor is displayed as a crosshair.

4. Click (or drag) in the spectral display to erase data.

   You can use the controls above the spectral display to adjust the erased area.

   • Width: sets the time range (in seconds) of the tool.
   • Height: sets the frequency range (in hertz) of the tool.
   • Hardness: sets the hardness of the eraser's edge. 0% creates a soft, feathered edge, and 100% creates a precise eraser with sharp edges.
   • Opacity: sets the strength of the eraser. 100% completely erases the spectral data under the eraser, and lower settings allow you to erase gradually.
   • Pen Pressure: select the Pen Pressure button to use pen pressure to multiply the Opacity value when using a tablet.

Cloning spectral data

Cloning an area allows you to duplicate data within a layer.

1. Create a new SpectraLayers project or open an existing project file.

   For more information, see Creating a new project or Opening a project or an audio file

2. In the Layers Panel, click the layer that contains the data you want to clone.
3. Click the Clone button . The cursor is displayed as a target.

4. Click the pick button above the spectral display — or hold Alt (Windows) or Option (Mac) — and click the spectral display to pick the source data that you want to clone.

   The selection is bound to the area you click in the spectral display. You can use the controls above the spectral display to adjust the selection area.

   • freq range (Hz): sets the range of the selection area.
   • time range (sec): sets the time range of the selection.
   • hardness (%): sets the shape of the selection area — 100% selects a raw block of data; 0% selects a block with feathered edges.
   • use tablet pressure: select the button to use pen pressure to multiply the power value when creating a selection.
   • transpose: select this check box to transpose frequencies. You can clear this check box when working with harmonic data to keep the structure of sound.
   • source: choose the source layer that you want to clone.
5. Click (or drag) in the spectral display to draw the cloned data.

Drawing a frequency

1. Create a new SpectraLayers project or open an existing project file.

   For more information, see Creating a new project or Opening a project or an audio file

2. In the Layers Panel, click the layer where you want to draw data.
3. Click the Frequency Pencil button . The cursor is displayed as a crosshair.

4. Click (or drag) in the spectral display to draw frequencies.

   You can use the power (dB) and use tablet pressure controls above the spectral display to adjust the drawn frequency.

   • power: sets the level of drawn frequencies.
   • use tablet pressure: select the button to use pen pressure to multiply the power value when drawing frequencies.

Drawing noise

1. Create a new SpectraLayers project or open an existing project file.

   For more information, see Creating a new project or Opening a project or an audio file

2. In the Layers Panel, click the layer where you want to draw noise.
3. Click the Noise Spray button . The cursor is displayed as a crosshair.

4. Click (or drag) in the spectral display to draw noise in the spectral display.

   You can use the controls above the spectral display to adjust the erased area.

   • Width: sets the time range (in seconds) of the tool.
   • Height: sets the frequency range (in hertz) of the tool.
   • Hardness: sets the hardness of the tool's edge. 0% creates a soft, feathered edge, and 100% creates a sharp edge.
   • Power: sets the strength (in dB) of the data you paint.
   • Use tablet pressure: when selected, pen pressure will multiply the opacity of the data you paint.
