French mathematician Fabrice Bellard, who founded the projects QEMU, FFmpeg, BPG, QuickJS, TinyGL, and TinyCC, has released the TSAC audio coding format along with tools for compressing and decompressing audio files. The format is designed for data transmission at very low bitrates, such as 5.5 kb\/s for mono and 7.5 kb\/s for stereo, while maintaining acceptable quality for music and speech. Using TSAC allows packing a musical composition lasting 3.5 minutes with a sampling rate of 44.1 kHz (stereo) into a file size of 192 KB, which will be almost indistinguishable from the original to the ears of an untrained listener. The project's code is distributed under the MIT license. <\/p>\n
