TSAC: Very Low Bitrate Audio Compression
TSAC is an audio compression utility reaching very low bitrates such
as 5.5 kb/s for mono or 7.5 kb/s for stereo at 44.1 kHz with a good
perceptual quality. Hence TSAC compresses a 3.5 minute stereo song to
a file of 192 KiB.
An Nvidia GPU is necessary for fast operation. CPU only is also
supported but slower.
