SHN > FLAC

I have converted most of my SHNs to FLAC. Usually they are comparable in size with SHN being slightly larger.

This one set of files is confusing me a bit. When I convert these SHNs, the output FLAC is half the size. Not that I can tell any difference in sound quality, but I'd like this archive to be lossless and FLAC. THe new file is around 350 kbps and the original SHN is around 800. I've converted hundreds of shows without anything like this happening.

Here are the SHNs:

If you convert the FLAC back to SHN, what do you get?
EAC secure | FLAC  --best -V -b 4096 | LAME 3.97 -V0 -q0 -b32

I checked the files, they are stereo but the 2 channels are identical or very similar, which FLAC will catch (hence the half size) but shorten does not.  both are lossless.

Your source files are probably mono.



yeah, I'm thinking there is something weird about these files. would mono explain this?

I convert to them wav and get the full size file, then convert back to shn and get the original shn

if I convert that same wav to flac, I get the small flac (half the shn size)

The easiest way to make sure there's not a problem is to do a bit-comparison between the decoded output of both files.
