Record /dev/dsp/

Woofcat · 10-11-2006, 07:28 AM

I use Skype to call people and sometimes i want to record the call. Is there any quick and dirty way to dump /dev/dsp/ to a mp3 or something? Using Ubuntu 6.06 LTS.

Sox...

Code:

sox -w -s -r 44100 -c 2 /dev/dsp -t raw - | lame -x -m s - filename.mp3

You may need to change this a bit depending on your setup.

Though, pretty much any sound recorder should work fine. If you use KDE then krec will do the trick. You will need to convert to mp3 manually though, as I believe it will be in wav format.

You could also use audacity. Just make sure your input levels are up and press record (the red circle button

)

Code:

jim@jim-desktop:~$ sox -w -s -r 44100 -c 2 /dev/dsp -t raw - | lame -x -m s - filename1.mp3
sox: Can't open input file '/dev/dsp': Device or resource busy
Assuming raw pcm input file : Forcing byte-swapping
LAME version 3.96.1 (http://lame.sourceforge.net/)
CPU features: MMX (ASM used), 3DNow! (ASM used), SSE
Using polyphase lowpass filter, transition band: 17249 Hz - 17782 Hz
Encoding <stdin> to filename1.mp3
Encoding as 44.1 kHz 128 kbps stereo MPEG-1 Layer III (11x) qval=3

It can't open it because skype is using it. Any other methods? Audacity yells at my for my sound devices not being configured.

You are using OSS then? OSS has issues with multiplexing.
You will likely get the same error from any other recording method unless using Alsa.

I am fairly sure i use alsa, since you know i use alsamixer to change my volumes etc.

jim@jim-desktop:~$ /etc/init.d/alsa-utils restart

is how i restart my sound. For some reason. Do you know why this would happen? Could i like some how system link it then record the link (Woofcat fails at understanding syslinking and tons of other stuff)

*Sorry but i still have the issue*

You'll only be able to do the sox thing if Skype uses ALSA. There may also be a hardware issue.
