want one audio/video utility that can help analyze recorded sleep noise (snoring).
Since majority of the long recording (about 8 hours) is silence. An utility is needed to make reviewing such snoring activity easier.
Here is the program spec. The utility needs to be able to do following:
1. For user picked file (whether audio or video), it give an analysis showing average noise level (or volume of the sounds recorded) per unit time (user definable, say one minute, 2 minute, 30 seconds etc.
the report should be an excel file, one row gives the time scale, another gives average noise level in that time unit.
2. with a user set threshold (say 25 db or 30 db etc), and a unit (say one minute), the utility will remove all the 'below threshold' part of the recorded file (audio/video). Therefore an 8 hour sleep recording may end up just 25 minutes, easy to examine. Important thing is that the utility needs to give a correspondence Excel file showing the relationship of the new mp3 to the long full mp3. Example would be "00:10:00-59" in new mp3 equals to "01:12:00-59". That way when we examine the recording snoring, we know when did it happen.
Coder can choose to use any language that he/she would want to use for this job.
audio recording will be mp3. video recording will be .avi
