Not sure someone outside uses this one, but maybe it would be prudent to have
kDecoderAVT = kDecoderAVT8kHz, just for backwards compatibility. If so, that
probably applies to kAVT, above, as well.

I'm leaving kDecoderAVT and kAVT as is then - compiler yelled at me for having
multiple entries with the same value in the enum.

Oh? Silly compiler!
