Title: Convert Stereo to 3.0
Post by: Koma on 2008-12-22 13:59:01

I want to convert a 2.0 (steoer)  signal to a 3.0 (with center speaker). Is it possible to do that for example with a foobar2000 plugin? Or is there another way to do that?
The equal sounds in both stereo speakers should be 'cut' and added to the center, so the middle of the "hifi-front" would be more present.

I hope you understood me and sorry for my English.

CenterCutGUI can do that. It will create two audio tracks: a mono Center one and a stereo Side one. Center will be whatever info is  "the same" between Left and Right. Side will be the difference. You can also select to send the bass info to the center or to keep it in the front channels. I would recommend do both, so every channel has bass.

I've written a plugin for foobar2000 based on [a href='index.php?showtopic=46611']this one[/a] which does what you want, except that the LFE channel (left empty) and the rear channels are also created. You can find it here (http://www.hydrogenaudio.org/forums/index.php?s=&showtopic=39404&view=findpost&p=560773). The plugin provides three variants that you can choose from in the DSP list. The variant "full rear" will create the front channels as you described. You can use the Matrix Mixer (http://www.skipyrich.com/wiki/Foobar2000:Matrix_Mixer) DSP plugin afterwards to remove any unwanted channels.
