howto record direct from the soundcard?

B

bigearsbilly

like one can do ls > /dev/dsp to send stuff to the soundcard
is there a way reversing it and recording what's playing?

e.g. your browser is playing a tune is there a
way to capture the sound to a file, wav mp3 etc?

Or a simple application. (CLI)

not including bloated gnome or kde apps with 300 hundred
library dependencies.

anyone?
 
Try out SoX http://www.freebsdsoftware.org/audio/sox.html - Sound eXchange, the Swiss Army knife of audio manipulation. I use it as follows on by Ubuntu box to get sound from my tv cable connection. It may work for you as well..

Code: 
sox -c 2 -s -w -r 32000 -t ossdsp /dev/dsp1 -t ossdsp -w -r 32000 /dev/dsp

It works with other programs too
 
It appears to record but just a blank file.

Code: 
$ rec 1.wav     

Input File     : '/dev/dsp' (ossdsp)
Channels       : 2
Sample Rate    : 48000
Precision      : 16-bit
Sample Encoding: 16-bit Signed Integer PCM

In:0.00% 00:00:10.07 [00:00:00.00] Out:479k  [  -===|====- ]        Clip:0    ^C

i've been messing about for hours, no luck

You are complicating things. It is certainly possible with sound servers: like audio/nas
 
Only some cards support recording the pcm channel directly. If your card and drivers support it, you would be able to run 'mixer =rec pcm'. You will likely get an error though, saying "unknown recording device: pcm".

You could also try the OSS drivers. There appear to be more options for what you want with OSS:

http://74.125.93.132/search?q=cache...+device&cd=3&hl=en&ct=clnk&gl=us&client=opera

And, finally, of course, you have the option of running a cable from the line-out on your sound card to the line-in and just recording from the normal "mic" recording device.

yes thanks adam.
I had tried the =rec and got the error.
I tried =rec vol

maybe it is the card, as it doesn't work with debian either
but debian does on my laptop.

thanks chaps,
i've moved on to ruby on rails now
