RFC 6716 Interactive Audio Codec September 2012 o ilog(7) = 3 2. It gets more interesting once we start to compare Lyra V2 against other audio codecs such as Lyra (V1) and Opus with the new audio codec delivering a higher quality (MUSHRA score) than those at a given bitrate, and the chart above shows Lyra V2 @ 9. I guess that my problem is with the GNU Auto tools Opus, the open standard, high quality codec. It seems that it does retain metadata when I play it back with an audio player like foobar(it shows up in the details tab, and the artwork in the artwork tab), but Windows doesn't see them, or its default music player. 2 open-source audio codec with ever lower high-quality audio bitrate for music (32 Kbps) and speech (12 Kbps), faster encoding and decoding, and other tweaks to the standard and library.

Opus audio codec (RFC 6716): API and operations manual. See also: OPUS_GET_VBR Opus is a general-purpose patent-free lossy audio compression format, a successor to Vorbis. Opus codec is actually composed of two audio codecs SILK for voice, and CELT for music, and automatically selects the one most suited to the audio type to provide better quality and a lower bitrate. That said, I am extremely impressed with it, and I believe it should just replace all the standard phone codecs. Opus, the open standard, high quality codec. One such function of OPUS code is implemented in FPGA logic using High-Level Synthesis (HLS). If you wish to contribute to Opus, I'm trying to turn the Teensy 3.
