[QUOTE="Bennett Prescott, post: 147719, member: 4"] Re: FIR filters I understand it about as much as I understand how my car works. I get the basic idea of a combustion engine, fuel/air mix, and the mechanics that move the wheels... but if I needed to actually build it myself it wouldn't work. Here's the Fulcrum page on TEQ: [url]http://www.fulcrum-acoustic.com/technologies/temporal-eq.html[/url] Some of Dave's [URL="http://www.fulcrum-acoustic.com/assets/pdf/whitepapers/spectrogram-loudspeaker-transient-response-2005.pdf"]white papers[/URL] have graphs that make it more clear what is being corrected in the time domain, shown using wavelet responses. It does take a lot of processing, but the final result is achieved without significant latency. IIRC about 1.4msec, most of which is due to the A/D D/A conversion. Fulcrum aren't the only ones doing interesting stuff with FIRs commercially, but they do go into the most detail about what they're doing so it's a great resource. [/QUOTE]
