 So if you import the 0.6.1-created mono file on Mac using 0.6.1, it's mono? A
mono M4A created by Audacity on Ubuntu using 0.6.1 still imports as stereo into
Audacity on Windows using FFmpeg 0.6.1 (as supplied in your installer).

I never use OGG files so it's not an explanation for me. Also speed of WMA and
AC3 exports are comparable to other formats for me.

So for you (from a generated tone), how much slower are M4A exports using "M4A
Files" and FFmpeg-with-native-AAC encoder, compared to other formats?
