that hificritic article is typical audiophile woo. utterly disgraceful.

the way to check if playback of LFAC is different than playback of WAV is to convert FLAC to WAV and then do a bit-for-bit comparison of the original and new WAV files. If they are different in any way, then there is an error (not "flaw", an actual algorithmic error) in the FLAC encoder and/orr decoder. If there is no difference, then there is no POSSIBLE way for the playback to be different (since the precise same bits wll arrive at the DAC.

Hello list,

My googling did not provide me with sufficient answers, so I'm directing my questions here ;-)

I made a 1 hour long project in Ardour that exports as a 635 MB wav-file.

>From Ardour the same project exports as a 566 MB FLAC file. However, if instead I use SoundConverter to convert the WAV to FLAC, the resulting file is 269 MB.

Since both are FLAC I'd expect them to yield the same playback (though after finding a report at hificritic [1], I wonder...)

Is there a way to check if those FLAC files are indeed 'audio identical'?

And, obviously - if the audio quality is indeed the same - I much prefer the smaller file. How can I tell Ardour to compress better?

Thankful for any and all input,
Al F
