Comments and Reviews
Opus is incredibly versatile and its introduction was a leap in audio encoding.
Its multi-mode/configuration capabilities allow it to equally-well support low and high bitrate/data scenarios, as well as low and high latency scenarios. Various encoding options give incredible versatility and customizability to the user to their needs.
The compression ratio is leaps better than previous and proprietary codecs.
When you do audio encoding your best choices are FLAC for lossless and Opus for lossy (but inaudably lossy by your choice).
Opus is amazing for everything, but APPLE, because they don't want to support it..
The best codec for podcasts or any other speech-heavy content.
Seems to be very promising. First tests were really good. Nice compression, and excellent quality. Looking forward to it.
