Package: normalize-audio
Version: 0.7.7-1
Severity: important

Hi.

I have a compressed CD file with flac (the whole CD in a flac file) that
is, unfortunately, due to the music industry, recorded with too much
dynamic range compression and way too loud.

This causes, in particular, clipping when the songs are compressed with,
say, an MP3 encoder (and then decoded).

As a way to remedy this, I chose to run normalize-audio (as I have been
doing for some time), but, today, I discovered the previously mentioned
CD file that after running normalize-audio, the post-processed file was
*shorter* than the original wav file.

In particular, if I:

* decompress it with flac;
* run normalize audio on it;
* try to compress it again with flac

flac complains that the file ended too short.

This must be a hard to track bug and I don't know if you will be able to
reproduce, but I can send you the whole CD image so that you can try. It
is, unfortunately, a 400MB+ long file and I don't know where I could put
it so that you could test it.

I also don't know if there are problems with 64-bit architectures (I
will try to use normalize audio on a 32-bit arch as soon as I have the
opportunity), but this is a very important bug, as it deals with file
corruption.

If you want any further information, please don't hesitate to ask. I
will try as hard as I can so that we can track it down and fix it.


Thanks, Rogério Brito.
