So, I have hundreds of .mp3 files in a folder. Almost each of them has a period of silence before you can hear a sound. And the periods are of the different size.
The same is with the end of the files.
Is there any application (free, if possible) by which I could trim all the files at once, so that each of them has equal time of silence ( for example five seconds) before and at the end of song.
Or, maybe a mp3 player which can adjust the silence of each song at the described way.
Also, If I must cut all the files one by one, which application is mostu sutable (i.e. speed enough) for this task)?
http://www.mptrim.com/ Maybe this is of help to you. I haven't used it though. – ap0 – 2015-08-28T06:30:56.397

@ap0 - the tool you suggest looks like it may not have the ability to calculate start and end silence of arbitrary length... the OP is after something to process the files where the length of silence at the start or end isn't fixed... The problem here is that without knowing a fixed amount of time to remove the average tool won't be very useful. I believe, in this instance, the ability to process the audio is required... thankfully, FFMPEG (free), may be able to come to the rescue: http://stackoverflow.com/questions/25697596/using-ffmpeg-with-silencedetect-to-remove-audio-silence

If you're going to need to analyse the silence in each track then it's going to be a big task... if you are going to automate this then FFMPEG should help... the results may not be guaranteed as I am unsure whether you can target the FFMPEG silenceremove filter to the start or end of a track - what defines the end of a track? Rehtorical question, but it's important if you're trying to find a tool to automate and give you the results you desire. You may need to do this one-by-one... Audacity (free) can be used to visibly analyse an audio track so you can work out where needs trimming – Kinnectus – 2015-08-28T08:05:47.990
@BigChris, thanks a lot for your help. I think, you should place your post as answer. – qadenza – 2015-08-28T08:12:13.303
This has been asked here before but cannot find it, anyone? – Moab – 2015-08-28T16:36:32.180
