General Audio / Re: Tested: codecs vs battery life on Android telephones
Last post by Marsu42 -https://www.rockbox.org/wiki/CodecPerformanceComparison
The rockbox comparison reminds of that Opus isn't one codec, but two - SILK and CELT, supporting threee modes - which probably shouldn't randomly tested together. https://wiki.xiph.org/OpusFAQ#Why_not_keep_the_SILK_and_CELT_codecs_separate?
Low bitrate Opus decoding seems to be significantly faster (i.e. should use less power for the same job), probably due to SILK being used?
On the other hand, modern Opus with LACE/noLACE post-processing on high decoding complexity settting is probably a lot worse performance-wise - but makes up for that by significant enhancement in <16kbps quality.
