I tried rendering a 5.1 surround 24/96 montage to surround MP3 and got half-speed audio. I’m guessing the converter doesn’t like 96kHz, but then I’m not sure if this is a WaveLab thing or an MP3 codec thing. I haven’t found anything definitive saying MP3 encoders require 48k or less. Is it necessary to do an intermediate render to 48k? No dither, I assume?
Any advice is appreciated.
