64000 Hz, 88200 Hz, and 96000 Hz AAC files are played at the highest possible samplerate
(48000 Hz with 12.288 MHz XTALI).

Also all variable bitrate (VBR) formats are supported. Note that the table gives the maximum
bitrate allowed for two channels for a specific samplerate as defined by the AAC specification.
The decoder does not actually have a fixed lower or upper limit.
