Hi,
I am working on audio source separation and have managed to separate a 2 channel stereo audio
signal into independent components (vocals and guitar).I want to upmix the vocals and guitar to
5.1 surround sound.I am working on the Matlab environment and have realised that all the audio
processing functions require that the data be in only 2 channels.Is there a work-around so that
I can do the upmixing in Matlab or do I have to use a specific package to do that?

Thanks
