jak nahrát co se přehrává do /dev/dsp

[Jaroslav Lukesh]

Dobrý den,

někdo se tu před časem poptával na %subj%. Když jsem si uklízel v
mirrorech, našel jsem tam vsound-0.5.tar.gz autora Erik de Castro Lopo

    VSOUND - a virtual audio loopback cable

This program allows you to record the output of any standard OSS
program (one that uses /dev/dsp for sound) without having to modify or
recompile the program.  It uses the same idea as the esddsp wrapper
from the Enlightened Sound Daemon (in fact, vsound is based on
esddsp).  That is, it preloads a library that intercepts calls to open
/dev/dsp, and instead returns a handle to a normal file.  It also
intercepts ioctl's on that file handle and logs them, to help convert
the audio data from its raw form.  Vsound then uses sox to convert the
raw data to the desired file format. 


A jde použít i takto:

     vsound -f output.wav realplay input.rm 

Zdraví JL.
