How important do you reckon FFT hardware acceleration A good question might be to think of what that acceleration is composed of, and that which you want to use it for. I can easily come up with professional use of certain FFT variations, including straight, medium long, and fully overlappi

Hi Martin, as I said in the other mail, I really like the OWL, however I'd probably have to do a hardware revision :P. Also I yet lack an estimate of how much more audio fx instances a true DSP can handle compared to an ARM, which is a crucial decision factor. Considering programming open sour

Hi Max, you might want to check out our OWL Pedal: http://hoxtonowl.com It's an open source, programmable FX pedal based on the ARM Cortex M4. If you are considering future open sourcing then bear in mind that most dedicated DSP chips require specialised tools to program them, which are generall

Wow! Truly stunned by the amount of feedback that came in over night, thank you guys! I'll try to go through it from the top, but in general I think it already seems to glimpse through that FFTs aren't as widespread in audio effects as I initially thought. I worked on a project at University f

A goto resource for spectral processing is Trevor Wishart's "Audible Design" - this provides sufficient detail for anyone fluent in programming to implement them using a standard phase vocoder. See here: http://www.trevorwishart.co.uk/publ_bks.html This is the basis of most of CDP's spectral

Greetings, I enjoyed the sound of these spectral audio FXs: http://www.michaelnorris.info/software/soundmagic-spectral). Does there exist some signal processing documentation of the algorithms? Jacob Den 25/08/16 kl. 05.18 skrev Ross Bencina: > On 25/08/2016 8:44 AM, Max K wrote: >> How import
