A tool to check for silent beginnings and endings?

Is there a tool that I can easily run in batch over many tracks at once that can check whether tracks start and end with digital silence or not, and just what the levels are if not?
Would be great to have as a foobar2000 component, but I'll take anything that can do this on many tracks at once.

I don't know, but Audacity has some macro features and stuff that might let you do something like that, so that's what I would look at.

mpTrim can trim off leading/trailing silence:

The paid version can do so in batch mode.

Thanks for the suggestions so far.

@Apesbrain I don't want to trim, I just want to verify, and it's going to be on lossless/flac files anyway.

@Brand I don't know... it takes a lot of time and RAM to open a whole album in audacity, and then, after running whatever macro I come up with, I'll have to browse manually to see what it's found, and all that I can think of with that would be the "find silence" function, which has a minimum of 100ms I think, and the results are displayed as label tracks. It would be less cumbersome to do as I do now, loading a single track with a spectrogram with a 60dB gain so that digital silence is visibly evident. But that's exactly the kind of visual checking that I want to avoid. I would like something that just scanned the starts and ends of track and said whether they start and end with digital silence or not (even if it's a very small, less than 100ms, chunk) or not, and, additionally, if there's a "silent enough" and/or "just background noise"  start and end.

@smok3 I guess that could work... if I knew enough scripting to make it, which I don't. In any case, I'm not scanning image files to find inter-track silences, like in the example you link, but scanning individual track files' beginnings and endings only. I don't care if there's silence in the middle or whatever. Would you say that should be achievable with SoX or FFMPEG and some scripting?
