Do I need to worry that these peaks could become 'overs' when the multichannel .wav is converted to AC3? IOW, should I be recording less 'hot' to account for possible overs from conversion? If so, what's a safe amount of headroom?
(FWIW, when I load my resulting AC3 file into Audacity , the peaks are still below 0dBFS. I presume this involves some sort of temporary conversion to .wav on the part of Audacity?)
Try as I might, I cannot figure out how to get WAVtoAC3 software to work with the interleaved multichannel .wav file that Audition outputs.
QuoteTry as I might, I cannot figure out how to get WAVtoAC3 software to work with the interleaved multichannel .wav file that Audition outputs. I haven't tried that... I've fed it separate files for each channel... And, I've only used 48kHz/16-bit. The funny thing is, the command line instructions for the Aften encoder (used by WAVtoAC3encoder) don't tell you how to use multiple files! BTW - Aften is "based on" FFmpeg, so I don't know how much difference there is. How big is your WAV file? The WAV spec limits files to 2GB (or 4GB?). I don't have WAVtoAC3encoder on this machine, but I think there is a setting to ignore file size. (I'm usually working with "movie length" WAV files, and I use separate files to keep the file size in-spec.)
