Harry,
This question has already been asked on the FLAC-Dev Mailing List. I
thought you were reading that, too...
Any software which supports multiple processors must be multi-
threaded. The process of designing multi-threaded code adds
complexity to the software, so there must be a good reason to go
through all the trouble. The procedure for decoding a single file
could only benefit marginally from being multi-threaded, because most
operations would need to wait until the previous operation was
completed. One section of the decoder might be able to process
several blocks, but the overall result would still need to wait until
all blocks are completed. Besides, managing dynamic buffers between
each step of the decoding process would actually require the decoder
to do more, meaning it would slow down to an extent. There would
pretty much be no difference in the total time, whether single
processor or multiple processors.
The best way to take advantage of multiple processors is to decode
multiple FLAC files at the same time. This will take full advantage
of your system, provided that the disk bandwidth and memory bandwidth
can keep up.

hi
has the flac encoder multi-core support (so I mean using 2 or more
cpu's simultaneously to encode 1 track at the time, not encoding 2 or
more tracks in parallel )?
And if yes, how to enable this?
thx
