I'm curious if there would be a chance that Stereo Tool could do/support Quadraplex encoding output in the future?
As you can read in the link, it seems to be fairly straightforward. You can still find Quadraplex FM radios on eBay.
Maybe utilizing two stereo audio cards simultaneously (or virtually) would work to get audio in from a quadraphonic record or from multi-track playback software?
Thanks for creating Stereo Tool as it is an awesome product!
