I'm interested only in AAC and because i'm having problems with Nero AAC encoding technique on my music player i am searching for any alternative solutions.
Here is a list of encoders. It does not state what the minimum and maximum bitrates it can achieve are, however.
Wiki PageIf the music player you are having trouble with is a portable music player, it might be that it only supports iTunes encoded AAC. (Some people have reported difficulty playing Nero AAC, despite the fact that the developers tell us that Nero AAC does not break the spec in any way, while iTunes encoded AAC play fine.) That being said, if the music player you are using is portable, it might be wiser to choose a lower bitrate setting, so that you can fit more music on there.
