When Opus has outperformed LC-AAC, HE-AAC, Vorbis at 64-96 kbps. I have also tested Opus 1.2 alpha vs state of the art HE-AACv2 encoder ( ~32 kbps, VBR, FhG) . https://hydrogenaud.io/index.php/topic,111798.msg930611.html#msg930611Opus 1.2 alpha was already better than HE-AACv2 at 32 kbps in my test and 1.2 release contained quality improvements too comparing to alpha/beta.You can throw in comparison with Opus literally any available codec.

Re: Opus 1.2 is out! Reply #53 – 2017-07-10 12:28:20 What happened to the official FLAC support on the Mozilla builds? Was working fine on opus-tools-0.1.9-win32 and then poof, it's gone. I tried both opus-tools-0.1.10-win32 and ...-win64Code: [Select]Error parsing input file: song.flacI did notice the 3rd party compiles by users of the forums, Was curious of the official status.

Couple mistakes and also use an eraser each time something makes.My thinking is, this would epitomize the approximate nature of the graph. Bonus points for fitting the entire graph inside a 8x8cm box, and use crayons to draw the lines.

Yeah, that's pretty much what I kinda thought of. Although a part of me wants to make this diagram a bit more complete, and update it with things like patents that have expired, like G.729.That, and adding "unfinished" or "experimental" codecs, like Codec2.

Especially AMR-WB+, AC3, Atrac, G.729, and G.729.1 (recently expired patents).

Combined with lib opus encoding, this should be able to target iOS 11 devices.*By add, I mean to its list of supported codecs.

Original: https://opus-codec.org/static/comparison/quality.svgMy rework: https://ss1.coressl.jp/listening-test.coresv.net/img2/quality6.svgMaybe AAC could also be extended to go below 32Kbps? The only problem is that quality and bandwidth is mixed, so it might be a straight line extending to the left.I think a better graph would be a graph that nearly looks the same, but with the 'narrowband, wideband etc.' sections removed and the color of the line determines the bandwidth.Like 'Yellow = Narrowband, Orange = Wideband, Fullband = Green etc.'

The quality and bandwidth is mixed, and it's a tricky problem. Adding a footnote for the Opus at 14 - 32kbps may be a better idea.Footnote: Opus at 14 - 32kbps is actually a fullband, but the quality is comparable to that of other wideband encode.
