MeGUI Audio conversion

[Devilman1]

I have a video with an AAC audio and I wanto to convert it to AC3, but the channel map of AAC and AC3 is different, will MeGUI also correct the channel Map?

TIA

Don't worry about internal channel map of codecs.

When you want recode the first pass is always decode the original codec to WAV format (PCM uncompressed with their standard channel order), the second pass is encode the WAV format to the new codec.

AAC -> decoder -> WAV -> encoder -> AC3

All decoders/encoders in MeGUI output/accept standard WAV channel map.
