Need a command line tool to analyze wave file and find noise |
|||||
Issue descriptionIn debugging crosbug.com/p/57587, I recorded the audio from headphone using chameleon, and need to manually check where the noise happens. We should add a command line tool in autotest using audio analysis module. That can 1. Read in a wav file. 2. Get channels to analyze. 3. Do the analysis on those channels.
