View Full Version : What would you use for high quality audio?

Let's say that you were encoding ~25 minute episodes using a total filesize of 335MB, giving plenty of space for audio. The obvious choice would be to use the demuxed ac3 files outputted from DGIndex. But how would you deal with the loudness factor (ie, explosions vs idle chatter)? Would you just leave them in anyway, or would you encode the ac3 file to something to try and "fix" it?

Or, is there even something better that I don't know about?

Hello,
I think if AC3 is posible, hold AC3 and postprocess the audio (i use FFDshow, to normalize, dynamics, equalize, Dolby, Mixer, etc.), is the better quality you can get because you don't re-encode the audio. If you want to re-encode i recommend OGG Vorbis or MPC (musepack) at 180kbps, because at recent Listening Test (Guruboolez), are the best codecs to that bitrate. Great audio quality! and you can pre-process before encoding with anything you want!

If you keep with ac3 you could use "ac3filter" in the DirectShow filter chain to compress the dynamic range.

Raziel6969 could you give a quick run down of how to process audio with FFDshow.I have used it to pre process video via avisynth but never thought about using it for this
