Stereo to Pro-logic

[arturjose]

Hello
i need your Help
is possible to encode 2 channels (stereo) to Dolby Pro-Logic ?
How ?
you suggest any tools or software to do this?
Thanks

sonic foundry, maven, protools, logic audio, audition, others.

And There is, IIRC, a DirectX plugin that uses a virtual PLII decoder to extract 5 channels.

I don't recommend these much, unless your material is already well suited for it (easily, cleanly separatable) and you are willing to spend MASS amounts of time.

Why don't you just use the "DPLII" or "5-ch Stereo" settings on your surround receiver, and leave it at that?

i want ENCODE stereo to Prologic
not Decode or extract.

Short answer - not without a lot of work, and even then the results may not be that inspiring. To create a proper ProLogic mix takes as much effort as creating a 5.1 mix, you just encode it to two channels with a PL flag at the end of the process.

A good PL II amplifier will give you just as good results from a straight stereo signal as you are likely to create yourself trying to get a multi-channel mix. I wrote this guide a while back for creating pseudo 5.1 from stereo -> https://forum.videohelp.com/viewtopic.php?t=292142

It is probably as good as you will get results wise without spending a lot of time cutting your source audio into pieces, doing a lot of keyframed panning, and virtually creating a whole new sound track from scratch.
