Re: [asterisk-users] How to record and playback at the same time
I'm going to go ahead and say that while I'm not one of the developers, I think it's safe to say that you cannot record to a file and play it back at the same time. Probably something like file locking (for the record, locks it from access by other processes, etc)...

Hello , Record the file and introduce echo this will give you effect of recording and playing at same time ;) On Thu, Jul 29, 2010 at 1:30 PM, Janu Mukherjee janu.mu...@gmail.comwrote: Hi, we are using Asterisk to record and playback.

File locks in Linux are purely advisory; it is up to the applications whether they choose to respect them. The only challenge is whether the header has been written correctly, and you should be able to do without that in a pinch. What happens if you copy the half-written file to a computer with speakers and try to play it through the speakers? /Benny -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Even (incorrect) headers are not a problem if you know the exact file format. apt-get/yum/pacman/emerge/whatever install/-S/whatever sox man (sox|play) Quick grep through sox source did not yield any fcntl functions, IMHO sox should ignore any locked files and you should be able to play them without problems.

Depending on what you are recording there might be two files, one for each leg of a call, until the call ends and the files are mixed. -- Jim Dickenson mailto:dicken...@cfmc.com CfMC http://www.cfmc.com/ On Jul 29, 2010, at 7:46 AM, Motiejus Jakštys wrote: On Thu, Jul 29, 2010 at 2:32 PM, Benny Amorsen benny+use...@amorsen.dk wrote: Sherwood McGowan sherwood.mcgo...@gmail.com writes: I'm going to go ahead and say that while I'm not one of the developers, I think it's safe to say that you cannot record to a file and play it back at the same time.
