Comparing TTA audio codec with three popular lossless audio compressors

This section compares TTA with other free open-source lossless audio compressors. All music files were WAV format files which were extracted from original audio compact-discs (CD). No pre-processing was performed.

1. Command line frontend for LibTTA version 2.3
2. Monkeys Audio v4.16 http://www.monkeysaudio.com
3. Wavpack v4.75.2 http://www.wavpack.com
4. Flac v1.3.1 https://xiph.org/flac/

For testing we use Intel(R) Core(TM) i3-3240, 3.4GHz, with 4GB RAM, operating under Windows 7 Professional. All tests were run on RAM-disk with capacity of 1GB.
