Hi,
I 've been searching the internet for two days and i couldn't find any satisfying answer, so I thought I'd ask here...
I'm running PD on my Raspberry Pi, and I need to record Pd's output. I can't use the standard writesf~ because I lack disk space, and oggwrite~ doesn't work well on the RPi (it records fine but Pd's output is trashed).
I recently discovered that i could record something in raw with ALSA using arecord, and pipe this into oggenc, or flac, or whatever I need to record the file. Something like:
arecord <parameters> raw | oggenc <parameter> file.ogg
The thing is that the RPi has no capture device (the single PCM doesn't seem to be capable of capture).
A lot of things seem to be possible using a .asoundrc configuration file for ALSA, but I don't know how to use it.
What I would want is to copy the PCM output so that ALSA can recognize this copy as an input in a record. Note that I need to be able to listen to the output while recording.
Do you thing this is possible at all?
Cheers,
Pierre.
