Hi folks,
New here, but I've been poking on the ProjectM source code for awhile now, so I thought I'd share my work here as there does indeed seem to be interest.
I've mainly been working on the "beat detection", but also have some MilkDrop compat improvements.
The existing projectM sound analysis is based on some statistical energy methods, I've replaced this with an FFT based approach. The results are IMO a dramatic improvement in the standalone version of projectM. I've ported the patch to the XBMC version of ProjectM, however the results are very disappointing..
It seems XBMC does not provide frequent updates of the audio stream to visualizations, so while the viz is running @ 60fps, the audio data is only being refreshed in the area of 10fps. At least thats what I observe.. I've seen one or two mentions of this elsewhere, so I assume its not just on my system.
I'll be looking into fixing this audio refresh issue in XBMC if I can locate its cause and then I'll look at submitting a patch to XBMC. Does anyone have any insight on this?
Anyway, if there's interest I'll definitely arrange to share my code, as I am also interested in having a good viz solution for XBMC.
