Final release of TAK 2.0.0 ((T)om's lossless (A)udio (K)ompressor)
This version brings a new codec that is both faster and stronger.
It consists of:
- TAK Applications 2.0.0.
- TAK Winamp plugin 2.0.0.
- TAK SDK 1.1.1.
- TAK Decoding library 2.0.0.
Download the archive in the upload section: TAK 2.0.0
This release introduces a new file format, which can not be decoded by earlier versions of Tak, Takc, in_tak and tak_deco_lib! But surely it can decode files created by any earlier version.
- Slightly better compression of CD-Audio for any preset (ranging from 0.09 to 0.37 percent for my primary test corpus).
- More than 2 percent better compression for my 8-bit test corpus.
- More than 1.5 percent better compression for my 192 KHz / 24-bit test corpus.
- Up to 0.45 percent better compression for my LossyWav test corpus.
- Higher encoding speed for any basic preset (without addditional evaluation level), higher decoding speed for any preset. Depending on the cpu up to 11 percent faster encoding for -p0 and up to 15 percent faster decoding for -p3 compared with V1.1.2.
- While the new codec is smaller than the previous one, the binaries are a bit bigger because the decoder for the old file format takes up about 18 KB.
- The file format is prepared to support some more future improvements.
- Added xrecode II to the list of applications with TAK support in the readme file.
- If you use pipe decoding and the application reading the pipe is beeing terminated before the whole file has been read, TAKC may get into an endless loop and has to be manually killed with the task manager. I don't think this is a big issue but i will try to fix it in one of the next versions. BTW: Big thanks to shnutils for testing the pipe decoding!
- There seem to be some compatibility issues with pipe decoding to some other applications ("crc1632.exe" has been reported). I will try to fix it in the next release.
What has changed in comparison to the beta release
- More than 1 percent better compression for my 8 bit test corpus. The modification may also help some very low amplitude 16-bit files.
- A bit better compression for some very special problem files.
You may find some useful information in the beta thread.
Plans for V2.0.1
Many, therefore i have to deceide what to do first:
- Tuning of the new codec.
- Implementation of some advanced features of the new codec which are already supported by the decoder.
- Evaluation of 320 predictors.
- Support for the Wave64 file format.
- Support for multi channel audio.
That's definitely far too much for one release.

I use -md5 key but TAK does not add Audio MD5 to the file. Why?
How do you know?
File properties in foobar2000.
Duration : 7:40.067 (20288940 samples)
Sample Rate : 44100 Hz
Channels : 2
Bits Per Sample : 16
Bitrate : 990 kbps
Codec : FLAC
Encoding : lossless
Tool : reference libFLAC 1.2.1 20070917
Embedded Cuesheet : no
Audio MD5 : 9D5656CD23D06A1E882AE329587D49DA
For TAK "Audio MD5" line is missing.
Also foo_verifier compares calculated MD5 with MD5 stored in the file. For TAK files this feature does not work
