Useful for audiobooks -> realtime silence delete
« on: February 03, 2011, 10:14:43 AM »
When listening audiobooks and author is talking slowly - yes you can timestretch, i know that there is this function but:
it would be useful if add function working like this:
when file mp3 is playing another thread or something is buffering sound into memory and scan and if find silence between words or somewhere longer that [configurable_by_user] for example 200ms -> change this silence to [configurable_by_user] for example 20ms.

This buffering thing is only my idea, i dont know from technical side how to do it but point is:
setting for deleting silence in music file longer than [configurable_by_user] to new value [configurable_by_user].
thanks.

This sounds like it would be incredibly complex to implement for something that would be of use to very few people. I'd be rather surprised if anyone chose to work on it.

I agree with AlexP. You'd be better editing the audiobooks in an editor like Audacity and adjusting the speed, deleting the silences, and doing other adjusts, for each file.

Yes, it takes more work (for you, not for the developers), but the result will sound better than any real-time automated silence removing and timestretching settings.

but your subconscious will use that knowledge.

eh? For the record, my "rather" was an understated way of saying "incredibly".

There would probably need to be some sort of threshold setting.  Sometimes "silence" isn't quite digital silent depending upon the original source such as analog tape hiss and condition of tape.

Not that it's going to be done...

It would also make the time remaining in a track or in what is in the buffer unpredictable which could cause buffering watermarks to not work as intended causing gaps while buffering. So yes, i'd also suggest setting up a pc side tool to do this preprocessing for you, maybe ther's one that can be scripted or otherwise automated.
