Audio.avs

Code:

#AudioSource
LoadPlugin("...\x64\ffms2.dll")
audio=FFAudioSource("...\audio_1_Undetermined.thd.w64") // 10 min , 8 channels
audio=ConvertAudioToFloat(audio)
#DownMix
Import("...\DownMixAudio.avs")
audio=DownMixTo6ch(audio)

audio=ConvertAudioTo16bit(audio)
AudioDub(video,audio)

CPU USAGE

It looks like that by using two separated processes we can gain extra ~23% of encoding speed.
