HALAC (High Availability Lossless Audio Compression) is now faster and denser with version 0.3.6. Also, for a long time, both encode and decode operations can be performed in multithread. This version now uses Rice coding instead of ANS. The Golomb-Rice coding for audio data is really excellent. And there are different things that can be done, both in terms of speed and compression ratio. However, at ultrafast speeds, in most cases we cannot move as freely as we would like. In the related link, versions 0.2.9 and 0.3.6 are compared. The results of the first version 0.1.9 are really behind.
