caudec: a multi-process command line transcoder for Linux, Leverages multi-core CPUs with lots of RAM Options

caudec 1.6.0 was released two weeks ago, with many new features.
There's also a new website: caudec.outpost.fr. The googlecode.com website will no longer be updated.
Version 1.6.1 was released yesterday, with the only change from 1.6.0 being updated URLs for the project.

I just released version 1.6.3 (see the changelog).
The most notable improvement is OS X fixes (thanks to TheLink).

Thanks for this. I'm using it on my Shuttle XS35GT (Atom D510 1.66GHz dual core hyperthreaded) to convert FLAC -8 to Ogg Vorbis -V 5.

Using Oggenc2.87 aoTuVb6.03 (Lancer SSE3 x64 windows build from rarewares), single core encoding gives me around 9x, while caudec yields 30x.

I realise this is pretty sedate by modern standards, but it's not bad for a 29w fanless netbook!

Yeah, I've used caudec on my netbook a lot, too. The CPU (Intel Atom) is so slow, it does make a significant difference. I also ran a silly experiment a while ago, where I got my netbook to endode FLACs faster (with two concurrent processes, using Flake) than my AMD Phenom CPU running FLAC with a single process :-P

Version 1.6.4 has a pretty cool feature for dealing with 2 mirrored music collections (e.g. lossless and lossy) at the same time: you can now specify a destination directory (with -o/O/P) after each -c parameter, in order to set per-codec directories. The files will then be written in the correct locations, without any further intervention. Example:

CODE

$ caudec -c wv -P "/data/wavpack" -c mp3 -P "/data/mp3" "Artist/Album [Year]"/*.flac

That command will transcode to both WavPack and MP3 at the same time. The resulting WavPacks will be written to "/data/wavpack/Artist/Album [Year]", and the MP3s will be written in "/data/mp3/Artist/Album [Year]".
