Hi list
I've asked help before about file plugin, and it does work fine.
But I need something more. The raw file from which I'm reading audio is:
Signed 16 bit Little Endian, 44100 hz, 2 channels.
I've configured asound.conf this way:
pcm.plugfile{
type plug
slave {
pcm infile
}
}
pcm.infile {
type file
slave {
pcm null
}
file /dev/null
infile /home/carlos/sting.raw
}
The input file is "sting.raw" (without header).
with arecord:
$ arecord -D plugfile out.wav -f S16_LE -r 44100 -c 2
Recording WAVE 'out.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
..
then aplay:
$ aplay out.wav
The sound is correctly played...
But I need to read the audio from another application rather than
arecord. And that application cant receive the format parameter.
So, I've tried doing this:
pcm.plugfile{
type plug
slave {
pcm infile
format S16_LE
channels 2
rate 44100
}
}
pcm.infile {
type file
slave {
pcm null
}
file /dev/null
infile /home/carlos/sting.raw
}
Here the "format", "rate" and "channels" are set up, and these are the
same as the original audio file. Then I suppose I would not have to
specify these parameters with arecord.
running arecord:
carlos@chaos:~$ arecord -D plugfile out.wav
Recording WAVE 'out.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono
it says Unsigned 8 bit, rate 8000 and Mono. And obviously this is wrong.
When I play with aplay no sound is played.
If I record again using "format", "rate" and "channels", the audio is
correctly recorded and played.
Any idea?...
thanks a lot
