Faster Audio Decoding and Encoding Coming To Ogg and FLAC (phoronix.com)

Posted by msmash on Tuesday May 22, 2018 @04:05AM from the backend-tech dept.

FLAC and Ogg now have faster audio encoding and decoding capabilities thanks to recent code improvements. An anonymous reader writes: Robert Kausch of the fre:ac audio converter project informed news outlet Phoronix about recent changes he has made to FLAC and Ogg for bolstering faster performance. Kausch says he updated the CRC checks within FLAC and Ogg to a faster algorithm and those patches have now been accepted upstream. The Ogg and FLAC updates were merged this week for using the optimized CRC algorithm. As a result of this, encoding and decoding FLAC is now 5 percent faster, while encoding and decoding Ogg FLAC is 10 percent and 15 percent faster, respectively. Opus sees about one percent faster decoding, while Vorbis does decoding at two percent faster pace.

Flac is lossless, it's full quality.
Opus, except at _extremely_ low bitrates, has similar or better quality than the most commonly used modern codecs:

Flac is fast to encode and decode. Opus decodes slower than MP3 but on par with AAC LC, and encodes slightly faster than AAC LC and on par with MP3. Performance will vary a bit by encoder:
