Re: [music-dsp] Supervised DSP architectures (vs. push/pull)

2016-07-27 Thread Ross Bencina
Hi Evan, Greetings from my little cave deep in the multi-core scheduling rabbit hole! If multi-core is part of the plan, you may find that multicore scheduling issues dominate the architecture. Here are a couple of starting points: Letz, Stephane; Fober, Dominique; Orlarey, Yann; P.Davis, "J

(Hi Matt, we've met before at NI btw, briefly) Thanks, I look these up, I think I browsed through some of this a few years ago, Rocchesso I think. I already had a hammer model for the same thing, which is piano synthesis and a soundboard model. For the moment I am more interested in spectral

[music-dsp] Supervised DSP architectures (vs. push/pull)

2016-07-27 Thread Evan Balster
Hello --- Some months ago on this list, Ross Bencina remarked about three prevailing "structures" for DSP systems: Push, pull and *supervised architectures*. This got some wheels turning, and lately I've been confronted by the need to squeeze more performance by adding multi-core support to my au

2016-07-27 Thread gm
Hi I want to create a signal thats similar to a reverberant knocking or impact sound, basically decaying white noise, but with a more compact onset similar to a minimum phase signal and spectrally completely flat. I am aware thats a contradiction. Both, minimum phase impulse and fading rand
