Dan Prince has just started a new video series which might interest a few here.
basic starting, and introducing Octave which is like an open source matlab which is useful for modelling.
go check it out, and give him some feedback/encouragement to continue the series
here is how Dan described it on KVR
In an effort to force myself to practice audio DSP algorithms, I have started putting together a video tutorial series where I explain the basics of audio DSP. I am aiming to teach music technology enthusiasts and other curious people just enough DSP for them to really get how common effects and synthesizers work by doing some mathematical hand waving, and pointing to relevant references for those interested in getting more theoretical. I think there is a real gap in the literature between Max/MSP level of technical detail and books that presume a degree in EE that I am hoping to fill with these videos by making them inviting to not-as-technical people.
I have many more ideas for videos in the future where I want to cover waveform generation, delay, modulation effects, distortion and non-linear effects, etc. I would love to hear your feedback on this first lesson!
