progressive effect?

Hello.
I would want to know if there is an effect which would allow to apply gradually an effect on an audio file. For example: at the beginning of the audio file, the effect would be only 1 %, and at the end of the audio file, the applied effect would be 100 %.
Thank you.

You can do that with most effects using this technique:

  1. Duplicate the track (Select the track then Ctrl+D)
  2. Apply the effect to the duplicate track as a “Wet” track (effect only).
  3. Apply a Fade-In effect to the duplicate track.
  4. Use the track Gain controls on the original (“Dry”) and the new (“Wet”) tracks to adjust the overall wet/dry mix.

Not that in step 3 you could use the envelope tool, or the Adjustable Fade effect for greater control.
