At now, mostly all of the popular lossless compressors gives the same compression results (difference about 1-3%).
The compression ratios of TTA depend on the type of music file being compressed, but the compression size will generally range between 30% - 70% of the original.
TTA is a hardware-oriented format. It means that the TTA format has a reasonable compression level, but WAS NOT developed to show top results in comparisons. TTA format supports both of ID3v1/v2 tags.
Using True Audio encoder you can to store up to 20 audio CD from your collection on one single DVD-R for playback, keeping all of CD information in a popular ID3 information tags.

Changes in TTA 3.4.1
- added support for standard input/output interface
- minor changes in command line options and error messages
- small bug fixes, and cosmetic changes
- some of submitted patches applied, including speed optimization,
changes necessary to support 64bit architectures, e.t.c.
- remove 32-bit floating-point data support
- changes related to compilation under MinGW gcc (windows)
- updated optimization options for gcc compiler in Makefile
- code cleanup: remove unused code
Being "lossless" means that no data/quality is lost in the compression - when uncompressed, the data will be identical to the original.
