I've released a classic UHJ to square/rectangle decoder which can be found at: https://www.brucewiggins.co.uk/?p=1836
It can also pass out B-format with or without shelf filtering applied. It's a JS effect, so Reaper is the ideal platform (there is a JSFX VST that should work on other DAWs, too). It implements both the shelf filters and forward preference controls as suggested in: Gerzon, M.A., 1985. Ambisonics in multichannel broadcasting and video. *Journal of the Audio Engineering Society*, *33*(11), pp.859-871. As an aside, looking through the old papers, it looks to me that the UHJ equations actually result in a W signal that's 3dB hotter than the SF mic standard (i.e. AmbiX gains!). Looking at the wireless world articles also suggests this (B format input to a unit that implements UHJ applied 3dB boost to W before decoding). cheers Bruce On Thu, 24 Feb 2022, 23:16 surround surround, <surro...@cox.net> wrote: > I have retired my Onkyo SV-909 receiver with a UHJ decoder after many > years of service.
