Is it true that the open source fraunhofer AAC encoder (fdk-aac) doesn't go above 17kHz? Even with 512kbps?

It is true, we can perhaps look at overriding this if possible for the next release.

I took a CD quality track which had 22.5KHZ audio converted to AAC FDK - CBR 512Kbps (on advanced page LC AAC selected), and the spectrum from it showed a cut off at just over 20KHz

Wow didn't know this so fdk aac isn't true 44,100khz?
CD quality is sampled at 44.1KHz, this would give a spectrum of the highest frequency of 22KHz, so FDK is 2KHz off that.

Do the frequency get cut when used vbr too? or just cbr?
