Is there a way to encode QAAC CVBR/TVBR at a bit rate between 160 and 192?

Been trying to do it in foobar and it just ignores anything i change the bitrate to, and encodes at 160ish or 192ish. Whichever i selected first before changing to custom. This is CVBR. Does the same for TVBR

Reason: 160 sounds good enough to me but i'd like to go a bit higher but not all the way to 192.  Would like the albums i'm encoding to be smaller than the LAME V2 encodes they will be replacing.

Cheers :)

--tvbr 82 (-V 82)
the final bitrate depends on the source. and delete "--no-optimize"

Is there no way to encode between Q 82 and Q 91 though?

I've no idea what "--no-optimize" does. It's in all the f2k default settings so i just leave it. I googled and couldn't find an ELI5 explanation of what it does :)

No. See https://github.com/nu774/qaac/wiki/Encoder-configuration#tvbr-quality-steps

IIRC foobar2000 do this optimization itself when it writes tags to a resulting file. That's why it tells QAAC not to do optimization, because its useless and only slows encoding down. (And m14u is clueless as usual.)

Q 91 it is then :/

:D

Sticking to what many people use is a safe option. 160k and 192k are both very popular but not the halfway between.

It's a limitation of the Apple encoder that it rounds to a nearest q or bit rate value instead of utilizing an ABR scheme to do partials. I know internally it has the ability (or close to it) to do custom ABR since it doesn't do true CBR (always going over or under the target rate). But I guess they decided to cut losses by only fixing bugs instead of adding more features that wouldn't be accessible in iTunes anyway (e.g., drop-down menus for rates), which IMO was a smart move because there were plenty of bugs that needed to be fixed; in older versions 320kbps would at times produce worse quality than 128.
