Apply volumne envelope from one track to another

[ramekin]

Hi. First time on this forum so apologies if this is the wrong place (but I am running unstable Audacity on Windows).

I want to use the volume envelope from one track to another (I think). What I actually need to do is be able to hear one track when someone is speaking but not hear it if they are silent. Is there a tool to do this? I don't think mixing with a vocoder would work, but I could be wrong.

Thanks.

ramekin,

No. I don't believe so. There is a feature called Time Tracks. It would be interesting to have a concept of a control track, where a control could be used to adjust timing, volume, or possibly even other attributes (eg. pitch, etc.)

I imagine you could go directly into the .aup file and edit the envelope control points. I've never done this myself and I don't know that it would work, but it just might. But don't tell anyone I told you to try this - I might get in trouble.

I think this would make a good New Feature suggestion.

Hi,

Thanks for the reply. I managed to get what I wanted in the end by writing a nyquist script (after intensive Googling) and doing the following:

(mult
(snd-avg (aref s 0) 4100 4100 OP-PEAK)
(aref s 1)
)

Where s 0 is the voice track and s1 is the breathing track (I think it's that way around, I did it a week or so ago now).

Thanks again for replying.

Could you clarify this. What have you got on which tracks and what do you want to do to which track(s)?

OK - see you've sent a reply while I've been typing.

Yes, sorry - I got impatient!
