Wavrate - Multiple codec evaluation software

Wavrate tool is designed for blind listening tests. Up to 8 codecs could be evaluated in one session. Built-in support for hidden reference + anchor (MUSHRA) testing like professional tests done at EBU. Some of the features:
  • Automatic randomization (no cheating possible)
  • Codec ranging from 1.0 (annoying) to 5.0 (excellent)
  • Slider for playback range selection (for long samples)
  • You can write your own tests
  • Built-in ability to allow comments for each sample
  • Easy-to-use GUI

Test sets
The files in these test sets are compressed with LPAC. They have to be uncompressed before opening a project in Wavrate, otherwise Wavrate will crash.
