Thanks Richard, but I donít think so. I own a SD 744 and as the manual you quote says, it records uncompressed PCM but can store in a variety of compressed formats, one of which is FLAC. To me at least, that only reinforces my point - FLAC is a way to store PCM or WAV, not an actual recording format.
In other words, it compreses digital audio, but is not digital audio in itself. That is not to say it isnít effective and good, just that it is not a format but rather a compression scheme. I would only use it to store audio for long termÖ not as preservationÖ
Like rtf is a way to store ASCII data, but isnít writing without it.
I donít know why I care so much, except that it seems the Australian claims are not what they think they are.
