TSAC - a neural network audio codec

A dvances in neural network development have led to the emergence of a new class of audio encoders capable of packing audio data even more efficiently than psychoacoustic encoders. The secret to their success lies in the fact that neural codecs use not only knowledge about the characteristics of the human auditory system, but also knowledge about the structure of music and speech...

Opus at high bitrates (128-192-256 kbit/s)

It looks like Opus audio format becomes popular. During last month SE received several requests to add it to the rating system. Low bitrate settings (--bitrate 59-90-96) were in the system since the first public release of the codec. Now high bitrates (--bitrate 128-192-256) are added as well. In contrast to other VBR encoders Opus uses “non-standard” bit allocation strategy for...
