recording oss output?

how can i intercept everything headed to /dev/dsp and record it?
thx 😀 :evil:
Oh and can I do it with ALSA also? I'm using ALSA-OSS emulation

I have no idea what alsa and oss's relation to /dev/dsp are, and actually that's something I've been wondering about lately. Why should apps need to be alsa/oss aware, if they're just writing to /dev/dsp? Confuses me.

I'm not really sure how to go about what you want to do, considering my limited understanding of /dev, but what app is it? You can probably just tell it to send its output to another file, or stdout, and then redirect that to a file.

Actually, its not exactly ME, I was talking to NuclearFusi0n over AIM and asked if he had figured out a way to record this kind of garbage from this thread:

Ive been away from Linux too long, i sorta want to learn it again, total noob now :Q I forget what app it is, but i'll see if he wants to come in here and actually say something himself 🙂 lol

mpd, bingbong. i want to record mpd's output. 🙂

/dev/dsp is an OSS only thing. apps that use OSS just write to /dev/dsp and vice versa. i'm not sure how apps communicate with ALSA though. confusing. 😛

Because ALSA doesn't use /dev/dsp without OSS emulation.
