Hi guys, Just wanted to know how much of multi channel recording can i do on a gumstix.. I need to record 4 different sources on to one hard drive.. I have done the same using an multichannel card such as MAUDIO and using some software to record on a PC .. But can some please tell me how such a configuration may be possible in a gumstix... Thanks in advance renegade |

I've seen no evidence that the Gumstix is even capable of stereo -- the software implementation seems to only support mono recording. I've been watching this issue for 3 or 4 months and despite several postings asking for information on stereo recording I've seen no indication that anyone has been able to do it. So as far as the audiostix goes, I'd say there's no hope. Someone else may have a suggestion of particular SPI or I2C ADCs that have worked well -- that's what I would look towards if I were you.

I've actually been able to record in stereo from the gumstix... I was planning to record different data from two separate mics at the same time, then later split apart the channels and have two output files of separate data. To test if this worked I plugged a stereo to 2 mono converter into the audio in on the audiostix2 board. Then I just did `brec -S foo.raw`(the -S is for stereo recording, the default is mono or 1 channel recording) while it was recording I had a friend say stuff into one of the mics while I spoke into the other. Sure enough when I did `bplay foo.raw` I heard a mixed sound file containing data from both the mics. I have not yet separated the two channels into separate files, but I have a feeling that it will turn out as expected.

I forgot to mention that I am using version 1183 of the buildroot because I do not believe that the audio is working in the newest version? I am not completely sure, but to my knowledge the latest version with audio support is 1183.

Joey -- did you change any mixer settings (with aumix, for example) before making your recording? Which driver did you load prior to using brec? Would you mind posting a list of the packages you had installed in addition to the default selections?

Here is everything I do before the `brec -S foo.raw` command: modprobe snd-pxa2xx-ac97 modprobe snd-mixer-oss modprobe snd-pcm-oss aumix -i 100 aumix -v 100 I hope this helps!
