Live Q&A with Ric Losada - Convolution: A Practical Review
Ric Losada - Watch Now - Duration: 24:02
the longest room acoustic impulse response i ever heard was a cathedral in England... they wanted to show how the echos significantly altered how a modern piece of music would sound in a long echo environment...i think it was a matlab based demo....
On circular buffers: I believe you can get rid of the if statement with a modulus operator to recenter back to start if the memory is aligned, but ymmv whether branch mispredictions vs. division is cheaper.
On slide SIMD Implementation: When doing SIMD, doesn't each register still rely on the prior results (the other registers) to finish? Did we shift gears away from the partial-parallel you were talking about for ASICs?
17:13:46 From Emanuele Ziglioli : Notch filters are single pole IIRs 17:14:03 From Emanuele Ziglioli : DC blockers, right? 17:15:56 From Stephane Boucher to Radu Pralea(Direct Message) : These seem to be something wrong with your audio 17:17:11 From Michael Kirkhart : High pass filters are typically used for DC blocking applications. 17:20:52 From Emanuele Ziglioli : Great talk, loved last year's one too! 17:21:23 From cblo : very good talk, thank you 17:22:09 From Emanuele Ziglioli : Since when has GCC been doing auto-SIMD? must have missed that! 17:22:35 From Thomas Wagner : Is that trustable vs assembler? 17:22:58 From cblo : btw the DSP system toolbox is quite furnished, good work 17:25:21 From cblo : I swear I'm not from your team 17:25:53 From Darkphibre / Amity : Thank you very much! 17:26:07 From Thomas Wagner : Thank you!
one very effective option... do the 5-to- down sampling in polyphase and then 1-to-5 interpolator to keep same input sample rate but have all operations at reduced sample rate.... always beats the IFIR filter which raises the sample rate and uses wider registers to hold the zero packed data.
