Can anyone tell me how to use the recording program "esdrec" on Fedora Core 2? I've tried:

# esdrec foo
opening socket, format = 0x00002021 at 44100 Hz
<ctrl-C>

But then I try to play it, I get:

# esdplay foo
Audio File Library: 'foo': unrecognized audio file format [error 0]

I've found it myself:

esdrec foo
esdcat < foo

I'd still like to know what kind of audio format esdrec/esdcat uses.

the manpage say its the raw audio .. I am not sure what it means .. but I think .wav files are in raw audio format too

Though you should be able to convert it into other formats like mp3 etc if you have the encoder

from

Then we can pass the sound to our favorite encoder. If you want something popular, lame does a decent job of encoding to MP3. If you’re doing music, you might want to use Ogg Vorbis, here oggenc will work just fine. For voice, speex (and speexenc) works pretty nicely.

If you want to stream more than one format, feel free to set up additional sound pipes; esdrec can be run as many times as necessary.

Finally, save the output to a file.

When you’re done, you should have something that looks like:

esdrec | lame - - > archive.mp3
