Adobe Audition 5.0 has a built in find silence feature.  I used to use it to edit our pastors 45 minute sermon down to 30 minutes.  After removing all the none essentials and still finding the sermon to long, I use the find silence feature to shorten the pauses in his delivery.  By the way, find and remove silence in this scenario does not return a usable product!

The feature allows for customized levels for 'silence detection' and 'audio restored'.  It would also allow for the replacement of a given length (or longer) of silence with a a predetermined length of silence, and then leave a marker in the file in all the locations where the function had been executed.

Yeah....im not a programmer though. Ive hackes out some code before but it aint pretty.

I was hoping more for something like "DAW X" has an automatic function that will find silence" im pretty sure that axtually exists in some DAW but i cant remembwr which.

The DUT is a dante AoIP device so a hardware sensor wont do it.  Anyway Dante Controller has some statistics and logging amd its not showing anything but flawless performance.

I suppose I could always listen ro 5 hours of 32 tracks of 1K tone.....

Im 99.9% sure the device is performing flawlessly without listening.

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
