9.3.4 Preferred Sample Rates
The supported session sample rates of the plug-in are from 32 kHz minimum to 192 kHz
maximum (where the host DAW allows). The supported codec sample rates are from 8
kHz minimum to a maximum of 48 kHz (MP3) or 96 kHz (AAC family).
Under certain settings at higher session sample rates, downsampling occurs between the
session and the audition path, or between the session and the encoder. This
downsampling is lossless to 24 bits.
The following tables indicate the preferred sample rates of the codecs (see section 9.3.2).
Only supported sample rates from 32 kHz and higher are shown.
