[SOLVED] voice recording program needed to record .wav for asterisk

Agustina · 07-16-2009, 10:10 AM

Anyone knows any program in Linux that can record an audio file:
8000 Hz, 16 bits, Mono?

Because I´ve been trying Audacity and I can´t record with that characeristics.

I have DreamLinux 3.0.

Thanks in advance!!!!

I set it up like this:

Audacity -> Edit -> Preferences -> Quality -> Select 16000Hz [OK]
Audacity -> Edit -> Preferences -> Audio I/O -> Select Recording, Channels 1 (Mono) [OK]

What exactly, is your problem?

That when I set those parameters (8000 hz not 16000hz)it doesn´t work with oss.

Look through your function codes. Asterisk has a call back where it will ring the extension of your choice and allow you to create the voice recording. Or you may have to create the function code.

Works just fine with alsa. Maybe try alsa ?

I'm pretty sure most distros support alsa. Give it a try.

I am not familiar with DreamLinux but your sound system configuration will probably be somewhere under "System, Settings"

Also, if audacity will not work with oss it suggests that other applications won't either (because the "backend" isn't capable of dealing with whatever).

Asterisk ???
I thought we were discussing Audacity. They both begin with "A" though

open a terminal and enter the following command,
arecord -vv -c 1 -f S16_LE -r8000 nameofyour file.wav

After you said that I had to go back and add a second look also. Damn those A words. At quick glance they do look alike.

However I think he should stick with using audacity. That is what we used to record our IVR prompts with.

@Agustina -- I post back when I have the feature code that will ring your phone.

Ok I got it. What you need to do is make a dialplan that will call the Record() function. This function takes in the following.

Record(filename.format[,silence [,maxduration[,options]]])

format - specifies the file type to be recorded
silence - # of seconds of silence before ending the recording
maxduration - maximum recording time

here is an example usage use # if you are done before max time.

Code:

 exten => 123, 1, Playback(pls-rcrd-name-at-tone)
 exten => 123, n, Record(/tmp/name.gsm,3,30)
 exten => 123, n, Playback(/tmp/name)
