 AAC-LC core encoder operates in dual rate mode at its lowest possible sampling frequency, which is 8 kHz.
 HE-AAC v2 requires stereo input audio data.
 
-The following table lists the supported bitrates for AAC-LC, HE-AAC and HE-AAC v2 encoding depending
-on input sampling frequency ("Hz") and number of input channels ("chan"). The minimum and maximum
-allowed bitrate ("BR Min", "BR Max") is given in bits per second.
-In case the desired combination of bitrate and sampling frequency is not available ("NA") for HE-AAC or
-HE-AAC v2 then the encoder will automatically switch to AAC-LC and give a command line warning.
 Please note that in HE-AAC or HE-AAC v2 mode the encoder supports much higher bitrates than are
 appropriate for HE-AAC or HE-AAC v2. For example, at a bitrate of more than 64 kbit/s for a stereo
 audio signal at 44.1 kHz it usually makes sense to use AAC-LC, which will produce better audio
 quality at that bitrate than HE-AAC or HE-AAC v2.
