upmixing mono to 5.1

[weirdaznboi923]

i know thats a really stupid question, answer is problably no, but i was just wondering because i want to upmix my home videos, but the camcorder records in mono (from 2000, sony CCD-trv37).

Why you wanna up-mix it... :confused:

Coz of DVD compliance maybe ???

AFAIK, DVD standard supports also mono (1ch) AC3 !!!

I think it is possible to insert some reverberation in mono files using sox (http://sox.sf.net) and encode to ac3 using BeSweet.

Check sox documentation for reverbration...:)

If you have mono PCM wave just create besweet mux file (some_file_name.mux ; this is plain text with .mux extension) like below:
mono.wav
mono.wav
mono.wav
mono.wav
mono.wav
mono.wav

If this won't work , create 6 separate mono files (mono1.wav, mono2.wav, .... till mono6).

Then just open this type of file in besweet like regular file and encode to ac3.
But MPEG standard allow mono ac3 (and AFAIR mp2)tracks on DVD.

You can upmix to true stereo or 5.0, if you use convolution with suitable filters (impulse responese). But it takes quite some time and you need to know some details. To get an idea on how it works, see The FIReverb Suite™ - audio demonstration (http://www.catt.se/suite_music/index.htm)

Andreas Thought this would only work proper with stereo sources as input... :confused:
