Record 8 separate Line IN Channels from M-Audio Delta 1010 Card
- by Peter Hoffmann
I want to record the 8 separate Line IN Channels from my M-Audio Delta
1010 Card. The card is recogniced nicely and a can record a single
channel via arecord -d 10 -f cd -t wav -D channel1 out2.wav. I've set
up the different channels in ~/.asoundrc.
Now if I want to record a second channel in parallel (arecord -d 10 -f
cd -t wav -D channel2 out2.wav) I get the error
arecord: main:564: audio open error: Device or resource busy
As I understand the delta 1010 is a single Access Card, so only one
application can access it at a time. Is this correct?
The next step was to configure a dual channel input in .asoundrc
# envy24 channel 1+2 only
pcm.test {
type plug
ttable.0.0 1
ttable.0.1 1
slave.pcm ice1712
}
Which works ok when I do a
arecord -d 10 -f cd -t wav -D test -c 2 out.wav
(BTW can anyone point me to a tool to split a multi channel wav into a
file per channel?)
But when I want to record the channels separately with (-I option)
arecord -d 10 -f cd -t wav -D test -c 2 -I channel1.wav channel2.wav
I get no recordings.
Did I miss something with the configuration or what are my options to
record all 8 channels via arecord.
I've no experience with jackd. Is it an option to install jackd and
record the line ins via jackd?
