Annoucement: Soft Matrix: Open-source stereo to 5.1 upmixer

It's my pleasure to announce Soft Matrix: An open-source stereo to 5.1 upmixer.

https://github.com/GWBasic/soft_matrix

From the README:

The goal of Soft Matrix is to provide ideal upmixing of two-channel stereo audio to 5.1 channels. Positioning of sounds are based on their panning between the two channels and the phase difference between two channels.

Soft Matrix's default matrix works very well with recordings that have significant out-of-phase material, and Soft Matrix has a horseshoe mode for recordings with significant panning; but mostly in-phase material.

Currently, Soft Matrix supports the RM and Dolby Stereo matrixes. The goal is to support common phase and panning based matrixes, including SQ. (Current support for SQ is experimental.)

Feel free to reply with any questions

(I'm writing this while listening to an upmix I made of Abba's Super Trouper. It nicely pans the lower register "sup-pap-pa trup-pa-pa" to the rear of the room.)

...it would be interesting to have as a Kodi plugin, IMHO...
