Abstract:
Optimal microphone volumes are automatically set for computer applications based on determination of peak volume levels and noise levels from one or more digital audio captures. The peak volume levels and noise levels can be advantageously determined based on distribution curves of sample volume levels in the digital audio captures. Clipping can be automatically compensated for by estimating peak unclipped capture volume levels from the distribution curves.
