[Asterisk-Users] controlling recording

We have no experience of providing a tool like the one you describe, but I'd
guess that AGI using sox/soxmix to edit recorded files should be able to get
you where you want.

The Trim options of soxmix provides the ability to, for example, take the
first x.y seconds of a recorded file so that you can splice a file in
accordance with a users instructions.  A second or any subsequent part of
the recording can then be made and concatenated to the first.

We use sox and soxmix in similar ways to allow some of our voice recordings
to be replaced.

Thanks for your quick replies - I had no idea this list was so responsive!

One more issue for you - we are trying to build a custom voicemail
application and so far everything works great by using AGI to play
prompts, get input and record files. However one of our customers has
asked for some pretty advanced functionality, specifically the ability
to:

* stop in the middle of recording (so far so good, escape character)
* fast forward/rewind the recording as it is so far (!)
* overdub (i.e. rerecord) starting from a desired point in the
existing sound file (!!!)

So, it's pretty clear that AGI's "RECORD FILE" function as it stands
is not going to cut it, so I'm assuming that do anything like this
means writing a new custom app_something.c, does that sound right?
Anybody have any tips or comments on how ridiculously difficult this
might be?

Thanks again,

John
