Remove silence in tracks with hidden track

Hello,

I'm looking for a solution to a tricky problem with my music library, was hoping to find some good ideas here.

Here is the problem:

It happens on some (rare) albums that the last track contains a long silence before an hidden track.

It's a common thing on some grunge album for example (prime examples being Nevermind or Ten)

On Nevermind: after the 3.46 min of the last track, there is a 10 minutes silence before that the hidden track start.

This kind of thing is not very common but it happens often enough to sometimes bother me.

For example when this kind of song with a long silence is picked in shuffle.

I'm looking for a way to get rid of those silences in the tracks.

I want to find a way to be able to get an exhaustive list of all tracks in my library during which a silence of, let's say, more than 30 seconds, can be heard (or not heard, since its silence...)

I seem to understand that a software is able to check tracks to spot silence.

For example I use Medieval CUE Splitter v1.2 to spit my cue flac tracks, and with this software, if you try to split an album in which silence can be heard: instantly when clicked on "split" a popup will appear saying something like "Medieval Splitter detected some silence bewteen track X and Y, do you want those tracks to be separated and silence removed?" (not the exact text but that’s the idea).

And it works perfectly, if you split Nevermind for example: track 12 will be Something in the Way being 3.46 long and there will be a track 13 being Endless, Nameless running for 6.50 ; and all the silence is gone.

So, apparently, this software is able to instantly spot silence in the flac file.

It's really an awesome feature of this software.

Would it be possible to do the same kind of thing with ITunes or with another program? :

Scan my library (or the source mp3 files) to find long silences (more than 45 seconds) and get a list of those tracks exported on excel or notpad… or anything (as long as it does not edit the mp3 file name).

After that I can, one by one, edit those tracks, removing silence using audacity for example, it's not a problem, I don't think it will represent way more than 50-60 tracks at most.

The only challenge is the hunting, to spot those full of silence tracks.

If you have any idea for a solution, using ITunes or not, or any idea on where I should look for this kind of thing I'm opened to anything.

Thank you very much by advance,

Max
