for me compaact would be more interesting if there was a commandline encoder, or at least something like nencode.exe...

Although the GUI does not support batch processing features yet, compaact! 1.1 does support command line encoding.
I am not sure if that's what you want, though.

I think he want something that he can use with EAC - which is what I want :-)

I hope rjamorim includes compaact 1.1 as one of the programs for the aac listening test

Hrm... I am a nut, but that doesn't justify including Compaact, given there are several other AAC encoders.

That being said, yes, it is my plan to test Compaact!. But discussion on encoders to be featured will only start in some weeks, and the test will probably start on February 18th or 25th.

Hmm, I was under the impression that this is no problem with the compaact! command line. What exactly does not work here?

There were two issues that I am aware of
1.  wrong audio object type in the case of main profile encoding (begin of November)
2. crash of 3ivx decoder (and only the 3ivx decoder) because one of the two sample rate fields was not set correctly (end of november)

Both have been fixed (see compaact! version history). Are there any other issues that I do not know?

Alexander: Have you tested with lots of different material what bitrates for example VBR-5 gives on average? Is it something like 125-135 or something else?

Hi,

we did not exhaustive tests, but with q5 the bitrate should range between 100 and 110. It could be higher for problem samples, though.

According to my own listening tests q7 or q8 is recommended for encoding music.

Alexander Lerch: With fatboy sample q5 bitrate is high enough (237kbps)

Right,

we are aware of this. This is for problem samples. However, the bitrate does not have to be that high here, so that will be changed in future releases. We noticed it too late to change it for this release.
For music input, there should be no such a problem. Here, to get standard bitrates (i.e. around 128kbps), q6 should used. Demanding users will encode at q7 or q8.
