GUIDE LIST: Stereo-to-Surround Conversion Guides

The following is a list of the various guides and methods posted in this forum for converting stereo to surround sound. It is meant to provide readers with a listing of all the methods posted as well as useful, related information.

Surround discussion and additions
For general discussions related to stereo-to-surround conversion, the methods, or for questions, you can post in the thread specific to a particular method or in the following general forum:

Additions and comments on "GUIDE LIST: Stereo-to-surround Conversion.."

An Overview of Plogue Bidule-based Methods
Many of the methods documented in this forum use a software package called Plogue Bidule, available from http://www.plogue.com. This program is currently free to use because it is still in a beta testing phase. The better you learn to use Bidule, the more successful your stereo-to-surround conversion will be.

For a detailed, step-by-step guide for conversion using Bidule-based methods, see Step-by-Step Instructions for Plogue Bidule-based Stereo-to-Surround methods

A basic overview of the conversion method is as follows:
  1. Install and configure all related software.
  2. Plan your project.
  3. Prepare your source file.
  4. Load the .bidule layout file and make any adjustments.
  5. Load your source file and use Bidule to create a 6-channel .wav file
  6. Process using Besweet
  7. Encode using AC3 or DTS encoding software
Server for surround projects
Most of the software and PDF versions of most guides with step-by-step instructions are available at Daphy and @ndy's server:
http://www.needfulthings.webhop.org/. If you have problems with this server, try ftp://daphy.mine.nu/. You can also check for announcements concerning the server status in the announcement thread, Needfulthings - dedicated 2.0to5.x host.

Daphy has put together a helpful Besweet installation package.

My apologies for the thread necro, but does anyone know if there is a method to use Harman Kardon's Logic 7 for upsampling to x.1?

@HaydenField000... it's possible to convert stereo to surround 5.1 via avisynth, using these filters (try them and choose one according to the results on your source):

UpAction() #action movies only
UpDialog() #dialogues mainly
UpGerzen()
UpFarina()
UpMultisonic()
UpSoundOnSound()

Once you have a 5.1 converted track, you'll just have to encode it using your favourite encoder, for instance, NeroAAC.

Sample script:

Code:
video=colorbars(width = 704, height = 396, pixel_type = "yv12")

audio=DirectShowSource("audio2.0.something")
#using WAVSource for .wav audio files is reccomend
#you can use FFAudioSource as well

audioDub(video, audio)

UpDialog() #it converts to 5.1
Please note that upmix it's not like a real 5.1 audio track, due to potential unexpected behaviours, 'cause it uses filters to detect frequencies and create channels, so you might have a light echo in FL and FR channels during dialogues, when they are supposed to be mute in a real 5.1 track etc.
Unfortunately, there is no magic and I really wanted to upmix audio tracks back in the days, but in most cases it's not worth it and it's better to just make a Loudness correction (Normalization, EQ etc).
