2) Do a 'file health check' version. i.e. one that can scan both 16 and
24 bit LPCM audio files. I already have a 16bit version but haven't
decided the best way to treat 24bit to get similar output.

I've now produced a RO program that does a statistical analysis on the
samples in flac format audio files. The analysis is similar to that done on
Audio CD tracks by CD_HealthCheck, so this new program is called - with
amazing originality - Flac_HealthCheck.

It can be obtained from

and it should work on 16 or 24 bit stereo files.

It uses the flac utility. I plan to do a port to Linux sometime, but source
code is provided in case anyone else wants to use it.

The current version has one quirk due to the way it reads the flac file in
5-sec chunks. This means that if the file isn't exactly a multiple of 5
seconds long, the last few secs are ignored. I plan to fix that once I've
written some more code to deal with it. However this quirk generally only
has a small effect on the resulting statistics and you can still spot if a
recording has flaws like those shown up by CD_HealthCheck.

Cheers,

Jim
