Music, Hertz/Frequency in general, works in Octaves, so Linearly, 0.5 against your 10,000 actually means, " 50% of Ten Octaves between 20Hz & 20480Hz is 640Hz, not 10k Hz."

Great timing! Was about to do a project with a teensy and many of these features.

I was literally just wondering how teensy and c programming does with real-time audio processing to do some dsp prototyping. You are amazing thank you so much!

Sadly the Audio Adaptor board for Teensy versions 3.0 - 3.6 isn't currently available. Only the Audio Adaptor board for Teensy versions 4.0 - 4.1. Kind of sucks that I have 10 Teensy board from backing the project on Kickstarter but not a single Audio Adaptor. I had originally planned to use these boards for RGB LED related projects so I never picked up these Audio Adaptor boards. Now that I'm doing things with Semi- Modular synths I'm regretting my life choices.

great video as usual. how about a teensy expression pedal (using an already existing generic passive expression pedal) for DAW's for controlling guitar effects like wah wah? i cant find an in depth and concise tutorial out there.

@NotesAndVolts Жыл бұрын

I believe those pedals are just a potentiometer in a special casing. Should work like a normal pot.

I'm building a band-pass and notch filter, which seems pretty straight forward using the Teensy audio library. But eventually I'd like to add a graphical display to show amplitude of the audio spectrum, as this would show the filter's affect on live audio as I make adjustments to filter parameters. Know any projects or code examples that have accomplished this? Or maybe this would be a project for a future video?

Can't deny, learnt from this, but still, with same money and effort could build multiple analog filters..

@nobodynoone2500 Жыл бұрын

Yeah, but you can have custom knob slopes, advanced processing. The simple filter is more of a proof of concept for making more complex devices. IF all you need is a resonant low-pass, I agree with you.

@NotesAndVolts Жыл бұрын

Yes, filters are not hard to build. But with this you could add chorus, delay, bitcrusher and more. It all depends on what you need.
