i think they are 'supposed' to represent a % quality.. but they are just high-to-low (or should it say low-to-lower... uh oh.. i better watch out for tos8)

Have you heard problems with a ~240Kbps VBR (Q98) wma 9.1 file to say it is low quality?

How about this new report (DBT and all) on WMA Pro quality?

1) If I follow the test procedure, the Nero files will be 64kbps LC-AAC, not HE-AAC. In their very detailed description, they simply didn't enable HE-AAC in the settings dialog. You can easily verify this with Nero 7 (even the free demo version should work).

You mean that when selecting “Nero Digital Audio (HE-AAC v2) (*.mp4)” only AAC-LC is used by default? If this is the case, you probably have a user interface design problem.

You select that "Nero Digital Audio (HE-AAC)" out of a list of MP3Pro, TwinVQ, WMA, AIFF, WAV etc.

By default, it will encode to 128kbps LC-AAC after selecting that.

Selecting the CBR/Stereo - 64kbps [HE-AAC] preset works correctly.

You have to go inside the encoder settings, force it to 64kbps CBR, and ignore the explicit combobox that says "LC (Low Complexity) AAC", to get it to fail this way. And that is exactly what their description says they did.

PS. I do agree this part of the GUI could be done better, but it can only fail this way by tinkering with some "advanced" settings and ignoring others. I don't think removing the LC-AAC options is good, either.
