View Full Version : MeGUI - Problem normalizing audio

Hi,
I have just updated MeGUI and am getting used to encoding audio via avisynth. I created the following script for my AC3>aac conversion -

LoadPlugin("C:\Utilities\MPeG 4 Stuff\AviSynth 2.5\plugins\NicAudio.dll")
NicAC3Source("D:\mY StuFF\Films\DVD\MYDVD\film T01 3_2ch 384Kbps DELAY 0ms.ac3", DRC=0, Channels=2)

This seems to work ok (and is a little faster than the directshow decoding option), but the aac output is quiet and does not sound normalized, despite checking the "increase volume automatically" radio button in the config box... When compared to the original ac3 I can tell no discernable differance in volume between the two, and my aac files encoded with the older besweet megui version are considerbly louder.

To fix this, do I have to specify a normalization command in the audio's .AVS script?
Thanks for the help :)
Dawson

Thanks for the info :) I have amended the script with the following changes, is this correct?

LoadPlugin("C:\Utilities\MPeG 4 Stuff\AviSynth 2.5\plugins\NicAudio.dll")
NicAC3Source("D:\mY StuFF\Films\DVD Rips\MYDVD\film T01 3_2ch 384Kbps DELAY 0ms.ac3", DRC=0, Channels=2)
audio = NicAC3Source("D:\mY StuFF\Films\DVD Rips\MY DVD\film T01 3_2ch 384Kbps DELAY 0ms.ac3")
audio = Normalize(audio, 0.95)

audio = Normalize(audio)
go for 1.0 :D
