recommended opus bitrate / opusenc setting for general?
...e recommended bitrate and further settings of opusenc (like complexity and framesize) for general music (e.g. including classical music) to achieve more or less transparency? Talking about CD level audio (16bit; 44,1 kHz; Stereo) The only source I could find regarding that was: http://wiki.hydrogenaud.io/index.php?title=Opus#Music_encoding_quality But that seems to imply that transparency is achieved with 256bit... and "close to transparency" wit 128bit... and then I wonder why one would need Opus, because I thought that's about the same for AAC/MP3/Vorbis. Cheers, C...

Multithreaded encoding?
...3B+). It saturates a single CPU core, but the other three are idle. Is out there any project to add multithreading options to "opusenc", or something in that line? Looking around, I have found this: https://github.com/enzo1982/superfast#superfast-codecs https://hydrogenaud.io/index.php?topic=114598.0 <https://github.com/enzo1982/superfast/blob/master/doc/SuperFast%20Codecs.pdf> Is it out there any other multithreaded "opusenc" drop in replacement?. Any plan for future "opusenc" improvement in this area?...

recommended opus bitrate / opusenc setting for general?
...an see, at that rate Opus ranged from slightly perceptible to imperceptible. Also importantly, note how few of the donors were able to give significant results on most tracks. This makes a 128kbps or higher test impractical as there would not be enough listeners capable of hearing a difference. The HydrogenAudio wiki should probably be updated accordingly. FWIW I cannot ABX 96kbps Opus from lossless, so that's what I use for music storage on my portable player.

SPEEX and OPUS questions and minor issues
I recently stumbled upon <speex/speex_resampler.h> and made a chain of discoveries: - "http://speex.org/downloads" some links are broken ("rarewares" and git) - there is some (minor) development (whitespace and more) of the "dead" Speex codec ... will there be a release? (I don't really need such myself) - there is some (more useful?)
