Envelope

From the Effects menu, choose Envelope to apply an envelope to vary the amplitude of a waveform over time. Unlike the Graphic Fadecommand, which simply fades a waveform by a specific amount over time, the gain at each point is dynamically calculated to achieve the exact specified envelope.

Apply an amplitude envelope Closed

  1. From the Effects menu, choose Envelope.

  2. Adjust the envelope to achieve the desired sound:

    1. Drag the small envelope points up or down.

    2. To create a new envelope point, double-click the envelope.

    3. To delete an envelope point, right-click it and choose Delete from the shortcut menu.

    4. To change the fade curve between two points, right-click an envelope segment and choose a command from the shortcut menu:

      Fade Type

      Fade In/Out Envelope

      Linear Fade

      Fast Fade

      Slow Fade

      Smooth Fade

      Sharp Fade

      Hold

  3. To move all envelope points, press Ctrl+A and drag when the envelope has focus (the cursor will be displayed as a ).

    You can create up to 16 envelope points. Click the Reset Envelope button to reset the graph to a simple ADSR (Attack, Decay, Sustain, Release) curve.

  4. Select the Smooth gain to minimize distortion on steep slopes check box to prevent the gain from changing too quickly, which might result in unwanted distortion. Also, when this option is on, the gain will always begin at 0%.

  5. Click the OK button.

Display the waveform Closed

Choose a command from the Show wave drop-down list if you want to display the waveform in the envelope graph.

If you're working with a multichannel file, you can choose to view individual channels or the mixed waveform.

The waveform is unavailable when the selection is greater than 300,000 samples.
