How-ever, Opus is at its core a waveform matching coder, and as the rate drops below 10 kb/s, quality degrades quickly. As the rate reduces even further, parametric coders tend to perform better than waveform coders. the perfect american philip glass

OPUS Codec Transcoding with PVDM4 & NIM-PVDM Voice DSP …

WebOpus is a relatively new audio codec that was created through a joint effort between several organizations based on two previously available codecs: SILK from Skype, and CELT from Xiph.org. Opus has seen a lot of press lately due to its receiving a newly IETF approved standard in RFC 6716. WebNumerous formats have since improved upon it's ancient format limitations from a sound quality perspective (e.g. not limited to 320kbps per frame). What makes this a significant improvement over either of these? Higher tested sound quality at lower filesizes (or in the case of most the usage scenarios, bitrates). In the end, it isn't lossless
