sounds like you need some software that "superimposes" a sine wave on the wav file and tests every sample against what it should be. an interesting project. perhaps it would read the first X cycles of the sine wave, average them, and compare the rest of the file against that average.

If I were given this assignment and could do it in realtime, I would setup a silence sensor with the shortest reaction time and utilize the status out to our local remote control (Burk).  I am doing this now monitoring our broadcasts with delay times set from 10 sec to 1 min.  I don't remember the shortest setting but I assume at least one second.  The Burk puts date and time stamps down to the second and writes them to an archive file.

I need a way to scan some multiple hour wav files for any momentary dropouts of audio. I am testing a piece of equipment running sine waves through it and recording the output. I’d like to find even one dropped sample but I suspect that if it does dropout it would be more like 500ms or so.

 

Thank you
