Full Version: FLAC Compression

Hi,

I am new to compression with Flac.
I have applied these compression settings:

-8 -V -T "artist=%a" -T "title=%t" -T "album=%g" -T "date=%y" -T "tracknumber=%n" -T "genre=%m" -T comment="%e" -T "comment=EAC (Secure Mode)" %s

I tried to compress a couple of wav files:

wav -> 92 MB
Flac -> 63 MB

wav -> 75 MB
Flac -> 54 MB

Is this the max compression I can get?

If yes, is there any other lossless format which has a higher compressor rate?

Thanks
Alex

Many codecs compress better than FLAC - FLAC is geared more toward fast decoding.

If your goal is purely compression ratio then I would suggest Monkey's Audio, LA or OptimFROG.

Check the wiki comparison.

Hi,

In Wiki it looks like Flac has a higher compression comparing to Monkey's Audio, 58,70 vs 55,70 blink.gif

Yes, I'm looking for compression.

Thanks

In the comparison, 100% is zero compression. Therefore, the lower the percentage, the better the compression.

You will want to read that the other way, where the percentage is the average size of the compressed file versus the original. With the numbers quoted, that gives Monkey's a 3% advantage.

The best compression I have had with FLAC was with this set of discs:

OK, I sse what you mean.

Many thanks

See this small benchmark for a nice comparison of various lossless codecs. I've just started ripping my CD collection and I use WavPack. It's MUCH faster when encoding than FLAC, and compresses a little better most of the time.
Other parameters can be considered though.

I would recommend this command line for FLAC :

-T "artist=%a" -T "title=%t" -T "album=%g" -T "date=%y" -T "tracknumber=%n" -T "genre=%m" %s

This command line uses FLAC's default compression level(-5). Using -8 will take about 4 times longer to encode and only give a neglible gain in compression ratio... Also i have never used -V(verify), because no FLAC version gets released without having completed a comprehensive test suite of several thousand streams, which gets through a encode-decode-verify process and must pass on several different platforms, and also because the only known reason for verify errors currently, has been because of bad hardware...

Yeah, but if you (unknowingly) happen to have this bad hardware, -V comes in useful wink.gif
