recording on 6 channels in same time

Post by MaximeLaporte » Thu Oct 19, 2017 6:11 am

Hi,

I am new with the octoboard and I want to recording on 6 channels at the same time. I try with this command :
arecord -c 1 -r 22050 -f S32 /home/pi/Desktop/test1.wav & arecord -c 2 -r 22050 -f S32 /home/pi/Desktop/test2.wav [...]
I have an error of material busy. But when I try with just one at the time, I can record on channel.

Do you have an idea of programme to use for recording on 6 chanels ?

Thanks,

Maxime

Oh yes,
You can try audacity which has a gui ... use the settings to set the number of channels you want to record from.

You can also record using :

Code: Select all

arecord -c 6 -f S32 -r 22050 /tmp/test.wav
Which records from 6 channels. IF you have trouble with that, try "-c 8" to record from 8 channels and see what that does.

thanks

Thinking about buying one of these boards for a project. Any reason one could not record each channel to a separate file with the right channel map in something like avconv or ffmpeg?

Thanks.

It can be done, check this thread out for information on how to record each channel to different files.

You can run encoders on each file if you like.
