Those interested in upmixing mono source material to stereo should check out my website, monotoSTEREO.info. The website provides a collection of resources for those using audio spectral editing, sound source separation, and related processes for upmixing older mono source material to stereo. In addition to highlighting a number of tools, there are over 700 research papers and presentations listed on the RESEARCH pages of the website. I continue to add additional content as time permits. I hope that you find the website interesting and informative! Be sure to also visit the companion Facebook page where I post updates about the website as well as related content!
