    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!

    The research section could use a more explicit way to find articles. Alphabetical organization makes sense if the end user already knows the title of the paper. Otherwise is fish in a barrel.

    I appreciate your comment. I'll consider adding something to supplement the lists at some point. Please keep in mind that there are over 700 research papers, presentations, etc. listed there! I tried to partition it somewhat so it would be relatively easy to scroll through each page and click on items of interest. A number of the top researchers in the field have contacted me and have provided numerous links to add to the listings. I hope that you find something interesting and informative there! Thanks for visiting the website!

    As far as advertising, the website is a not-for-profit informational website. I don't make a cent off of it and pay for it out of my own pocket. Also, any mention of where this type of technology is being used commercially is simply to point out where samples of it can be listened to. The VoiCode plugin, while certainly interesting for adding a sense of "space" to a mono source, does not separate individual instruments and/or vocals which can then be panned across a new stereo mix. One advantage of the VoiCode plugin is that it operates in real-time, allowing it to be used in live settings.

    I find the topic very interesting - I was encouraged to see that you include Samplitude ProX 2 in your list of tools.

    As long as this isn't a for-profit site, I have no issues with links being posted, and look forward to learning things from your research that I don't currently know.
    IMHO of course.

    I should point out that upmixing mono to stereo using spectral editing and/or sound source separation is still quite time-consuming and tedious at this point. I estimated that the track that I worked on which was released commercially back in 2005 (which can be heard on the MEDIA page of the website) took approximately 60 hours for the separation alone. That was using a free spectral editor called Frequency. A number of applications which have been released more recently include harmonic tracking as well as tools specifically designed to help separate transient type content such as percussion from a mix as well as separate vocals from a mix. Audionamix has pioneered the use of a cloud-based solution which does some of the heavy lifting "in the cloud" and automates the initial separation process. It will be very interesting to see the applications that will undoubtably be released in the coming months and years which will help automate the process further!

    Being that you have Samplitude listed as one of your tools, I'm curious as to why you didn't use Samplitude's Spectral Editing...

    Trolling for hits on freeware instead? That's my guess. :)

    The listing of tools on my website are not of the tools that I have used, although I have used and own many of them. I have listed numerous spectral editors and sound source separation applications which are available. I don't own Samplitude. I use only Macs for my audio work and Samplitude is Windows-only. I did download and install a copy of the demo on a PC running Windows at my job so that I could try it and also take a screenshot of it to include on my website. As for including freeware, it is important that people know that this type of upmixing can be performed even with free software. Unfortunately, it is a very time consuming process and the free applications don't include many of the more sophisticated tools included with commercially released applications.
