audio sampling Skews!
hi, i am working on the Zaurus handheld and am trying to have a bunch of these devices simultaneously record audio with a microphone. ideally, given that all Zauri "hear" the same sound, the resulting audio files would be almost exactly the same. for example, a clicking sound at regular 1 second intervals results in audio files that produce clicking sounds at regular 1 second intervals.
however, the problem is that the resulting audio files are NOT the exactly the same. after an hour or so, the audio files are off by up to 2 seconds which is unacceptable. doh!
i am looking for suggestions. is it hardware, software, or other related? how can i test and experiment to hopefully identify the problem? thanks.
