Stereo to 5.1 Unwrapping Plug-in for Audition

Trying to do a quick stereo-5.1 conversion. I know it's not ideal but in a crunch. I was wondering if anyone here had had success with any tools or plug-ins or a workflow that works. There's a free DCP creation tool called DCP-o-matic that does it so there MUST be some open source code out there. Most of the commercial stuff is like $400 which seems excessive. Thanks!

    Does it put anything in LTE? Thanks!

    There is no LTE but there is an LFE, and no, signal should not be going in it, as it stands for Low Frequency Effects. Like thunder and explosions, etc. Since Audition can't determine program content, then it won't put anything in that channel.

    The preset does the following:

    L = 100% (0dB) L

    R = 100% (0dB) R

    C = 70.71% (-3dB) L + 70.71% (-3dB) R

    Ls = 70.71% (-3dB) L + inverted 70.71% (-3dB) R

    Rs = inverted 70.71% (-3dB) L + 70.71% (-3dB) R

    LFE 0%

    The Channel Mixer effect in Audition has a "matrixed stereo to ITU 5.1 preset". Put that on a 5.1 master or bus and feed it a stereo signal and it will populate L/C/R/Ls/Rs.

    Thanks. Almost seems too easy. Does it do it in such a way that separates out the center from and lowers the db of the other channels? Does it put anything in LTE? Thanks!

    Interesting. Well if a lot of systems (particularly in people's homes) ARE

    relying on the subwoofer for bass that would suggest you SHOULD throw the

    low tones there even against spec but NOT do it for distribution to a movie

    theater which DCP-o-matic is doing.

    The redirection of bass to use the sub to make up for any shortfalls in the main speakers in home systems should be done in the replaying amp and not in the 5.1 soundtrack.

    I use the ADL pentio 5 Composer vst plugin in an audition multi track session. you will need an iloc for authorization.
