I've been looking into moving up to lossless audio files. From what I've been able to discover, FLAC and Apple Lossless should be roughly the same file size, but I downloaded a 24-bit/44.1kHz FLAC from the Bowers & Wilkins site (about half-way down the page - search for Portico) which is 35MB. I transcoded it to Apple Lossless using Max and the resulting file is 62MB - 77% larger!!
Does this seem right? Is the compression level variable for FLAC and/or Apple Lossless (as there is for ZIP for example)? There's no such option in Max. Do I need a better transcoder?
Also, in this thread someone says:
FLAC files are slightly smaller and ALAC due to a slightly better compression ratio (but only very slightly).
which confirms what I was expecting.
