now...i want to open all the devices at the same time. and have them save to one single wav file. As if i'm opening one single alsa capture device with 8 channels. the saved wav file should look something like this (take this 8 channel wav file for example)
First Multichannel Sample
{BB FF FF} 3 bytes slot1 {A1 FF FF} 3 bytes slot2 {00 00 00} 3 bytes slot3 {00 00 00} 3 bytes slot4 {00 00 00} 3 bytes slot5 {00 00 00} 3 bytes slot6 {00 00 00} 3 bytes slot7 {00 00 00} 3 bytes slot8
Second Multichannel Sample
{E6 FF FF} 3 bytes slot1 .,.. etc ....
Is this possible and if yes how can i do that?
For such a task usually I'd use JACK on top of ALSA with the alsa_in/alsa_out scripts or the Zita tools.
Good luck, Geraldo Nascimento
thank you guys
