ENVELOPE FOLLOWER

Hello,

I am a novice in the audio field and I have been working with Adobe Audition for a while. It has a tool named "ENVELOPE FOLLOWER" which works as follows:

I load 2 audio files in 2 different tracks and then I select one track to follow the volume of the other. I use this feature to make subliminal audio files so I always use music (a masking sound) in track one and the spoken messages in another track. I can specify how loud the spoken messages will be with respect to the masking sound and other parameters which means that the spoken messages can be hidden in the masking sound.

Does AUDACITY have a feature like this?
or
Can I achieve this effect with AUDACITY?

Respectfully,
Jorge Maldonado

Audacity does not have that effect, and I've not seen a plug-in to do it.

You could emulate a crude version of the effect by using the "Auto duck" effect - first apply it to a dummy track containing a continuous tone, then use the dummy track as the control track and repeat the effect on your second track. This would be "crude" because it would not accurately follow the dynamics.

You can do it manually with the envelope tool, but this would be rather laborious.

You could create your own Nyquist plug-in to do it. http://audacityteam.org/wiki/index.php? ... rogramming
