Hi peeps,

Short story
qaac he cvbr 128 (or higher) always ends up in 82 kbps. Why?

qaac.exe --raw --raw-rate $(SampleRate) --raw-channel $(Channels) --raw-format S$(SampleBits)L --he --cvbr 128 -q 2 --threading --title "$(Title)" --artist "$(Artist)" --album "$(Album)" --track "$(Track)" --date "$(Year)" --genre "$(Genre)" --comment "$(Comment)" - -o "$(DestFileAudio)"

Long story
I was actually searching for the best compression method out there, since I have a lot of 320 kbps music that's taking too much place. Reading the latest listener test (2014), I tried & concluded the following:
  • Opus (v 1.1) is a definite winner! Even claims that at target bitrate of 96 it is almost transparent! (=Imperceptible!).
    But, yeah, most devices (that I use) don't support it yet. So, no option for me. :-(
    -
  • Second winner is QAAC (iTunes 11.2.2 via qaac 2.41). But
    • tvbr option crashes mediacoder (or at least the "job" and MC can't stop it, so I have to force quit MC).
    • cvbr 128 works, but whatever target bitrate I put there (even 480) the song always ends up at ±81kbps.
      I tried 4 songs (blues, rock, noise ambient, monks singing). Is this normal? Does qaac decides not more is needed? I can't imagine that it' then the same for every song?!
