I would like to adjust the volume using keyframes.
When I edit a clip from Premiere Pro in Adobe Audition the sound track waveform appears on Audition but I cannot adjust the volume using keyframes.
The pointer tool and other tools are greyed out.
Do I have to go to a multi track configuration to use the keyframes?
Basically yes you have to have your file open on a track in the Multitrack view in order to Volume envelopes with keyframes. However the is a Gain Envelope to which you can add keyframes under Effects/Amplitude and Compression but, unlike in Multitrack, it is not real time and has to be processed.
