Overview
aurecord(1) is an internal command to the signalPAK routines and is not intended for direct command-line use.
aurecord(1) records time seconds of channels channel audio at rate. If the -e option is specified, recording doesn't begin until there is a signal to record, and stops when the signal ends, so it is great for capturing a bit of speech without having to remove the surrounding silence.
The data is written to stdout as:
4 byte rate (machine format)
4 byte number of channels (machine format)
2 byte channel1 channel2 channel3 ... (machine format)
2 byte channel1 channel2 channel3 ... (machine format)
