Please be aware that much of the software linked to or mentioned on this forum is niche and therefore infrequently downloaded. Lots of anti-virus scanners and so-called malware detectors like to flag infrequently downloaded software as bad until it is either downloaded enough times, or its developer actually bothers with getting each individual release allow listed by every single AV vendor. You can do many people a great favor when encountering such a "problem" example by submitting them to your AV vendor for examination. For almost everything on this forum, it is a false positive.

Linux software for "soundfields"

Is it possible to duplicate the soundfield synthesis DSP processing that receivers have been doing for quite some time in quasi-real time under Linux? (I say quasi-real time since I can tolerate lag.) I particularly liked the "Hall", "Jazz", etc. settings that was part the Cinema DSP on my recently deceased Yamaha receiver (forget the model number...vintage of approximately the turn of the millineum), but would like to be able to adjust the various settings for grins. This would involve up-mixing, ideally from 2 to 5.1 channels.

Yes. It is possible. It would require quite some coding (programming) effort on your part, as well as a substantial bit of information on exactly what the "soundfield" you liked was.

The processing itself is not particularly scary for a modern I3 or I5, or equivalent, and can be heavily parallelized as well as pipelined.

Thanks for the response. It would be a fun project to code up but would take more time than I can commit. (I write DSP heavy code partly for a living so my hobby time is spent on something else. :) )  I was hoping that someone had already done it for me, though, but apparently not. It looks like the best bet is to just get another Yamaha receiver.
