Is the built-in aac encoder better or as good as fdk-aac? I've been using fdk-aac because it gives lower bitrates and better/same sound.

  libfdk historically always was a bit better and supports VBR properly. See also: https://trac.ffmpeg.org/wiki/Encode/AAC https://trac.ffmpeg.org/wiki/Encode/AAC

    That's why I've been using it. Is the improved built-in encoder on par now?
    • slhck 11y ago
      I haven't done or seen any tests, but I suppose if you require VBR and/or HE-AAC support, go for libfdk, otherwise for bitrates ~128k or higher, use the internal AAC encoder.

  Official docs say that it's competitive at 128kbps, but these[0] listening test from Kamendo2 (who's very experienced in ABX listening tests of lossy codecs) suggest fdk-aac still has the edge, as well as handling VBR and the HE-AAC / HE-AACv2 profiles properly.

  On a related note, how do those options compare to Vorbis and Opus, technically and legally? Is there a compelling reason to use AAC over those choices?
