QAAC TVBR? - erickhc - 27.04.2024

I searched for an answer about this, but I couldn't find any.

Why isn't TVBR available for QAAC?

It usually outputs smaller files than CVBR, from my experience, encoding the same files with MeGUI.

Thanks in advance.

tvbr is supported,...
-V, --tvbr <n>         AAC True VBR mode / quality [0-127]
it's the quality factor. Smile

Thanks for the quick reply. This is what I get. Is it only visual, then?


RE: QAAC TVBR? - Selur - 27.04.2024

The bitrate mode is disabled and is not taken into account for quality encoding.

Amazing! Thanks for the clarification! Heart

For some reason, I don't see the qaac selection check box


RE: QAAC TVBR? - Selur - 01.05.2024

a. qaac is Windows only
b. qaac requires the 'Apple Application Support', which comes with Quicktime and Itunes and due to license restrictions can't be shippend with Hybrid.
Hybrid checks a. the registry and b. whether a portable version of the Apple Application Support is present, see: https://forum.selur.net/thread-1913-post-12443.html#pid12443 for details
