Re: [music-dsp] Music software interface design

By the way, related with interface design, I have just backed this project : https://www.kickstarter.com/projects/1795693416/push-turn-move-interface-design-in-electronic-musi?ref=category It's a book called "Push Turn Move" about interface design for both hardware and software in electronic mu

Re: [music-dsp] Changing Biquad filter coefficients on-the-fly, how to handle filter state?

Have a look also for the book "the art of virtual analog filter design" by Vadim Zavalishin. It provides a new structure for simulating state variable filters especially suited for time varying cases. Ivan MusicalEntropy.com Blog

Have a look for this project, it includes a wrapper for the vDSP FFT, Ooura's FFT and FFTW, with uniform partitioned convolution algorithms https://github.com/HiFi-LoFi/FFTConvolver Ivan MusicalEntropy.com Blog | Twitter

Hi Stefan You should have a look also for the compilation code / "floating point model" option in VS2008, which can be set to "precise" or "fast" Ivan COHEN R&D PhD engineer Le 25/02/2015 10:51, Stefan Sullivan a écrit : Hey music-dsp folks, I know

Re: [music-dsp] Simulating Valve Amps

ile. Anyway, I have appreciated a lot to be able to compare this stuff with what "synth filter guys" do, thanks to KVR and "zero delay feedback filters" discussions in general, and I'm sure that all the approaches will be done better by mixing all their best elements.

Re: [music-dsp] Noise gate for guitar amplifiers and hysteresis

Hello rbj ! What do you mean by "slew" ? Is it a filtering applied on the VCA attenuation ? I think the answer to your question is obviously no :) I may have missed a point in the implementation of noise gates. I would be glad if you can detail a little... Thanks ! Cordially,

ot;, and I can't apply G1, because the gain must not change too fast. So my question is : what is the best way to handle the move between the gain G1 and the gain G2, while preventing chattering, and clicks ? Thanks in advance ! Ivan Cohen. -- dupswapdrop -- the music-dsp mailing list and we
