VCD and Dolby

[kabibe]

Basing on the posts I read on this forum, Dolby Digital can't be encoded for VCD's but Dolby Pro-Logic can be (hope I'm right ).

my question is: how can I turn my regular .wav file and encode it to be Dolby Pro-Logic "compliant" and later merge it on my video and encode it to MPEG using TMPGEnc?

thanks for your time!

When you encode the Movie, or whatever it is you have, put the audio setting to dual channel and whatever bitrate.

I think it is dual channel but it might be joint stereo.

If anyone can confrim that would be great

Anyways its one of those two.

When you have your movie done stick it in the vcd/dvd player then put your amp at the Pro Logic Setting

Its one of those settings. You should wait till someone confirms

hope this helps a bit

that's all? i mean, i don't need any other (encoding) programs?

Thats right.

I just cant remember which one it is thow.

either one will work fine (joint or dual). They are simply different methods of encoding the stereo signal. Dual Channel is just what it means, the left channel remains the left audio channel, and the right channel remains the right audio channel. With joint, the Left and Right are combined to produce a single mono signal, and then the Left and right are subtracted from each other. (This is how fm radio stations broadcast they're stereo media). The idea behind this is that more bitrate can be given to the mono signal (which has the most important part of the sound), the "expansion" signal which is responsible for making the mono sound into stereo again, doesn't need as much bitrate. Anyway, back to the topic, Dolby Pro Logic works on the analog stereo signal, doing simple mathematical processes to extract the center, left, right, and subwoofer signals out of ordinary 2 channel stereo...There is no need for any other type of software. If you are creating a vcd in tmpgenc, stick with the template (i believe the default is joint), because you might make a vcd that can't be played on some dvd players. Here's the down and dirty data.

Joint Stereo - Better quality sound overall, but the stereo expansion could be affected as a result.

Dual Channel- Better stereo separation, the left and right are preserved, but the quality of the sound will deteriorate
