    Teensy 3.2 with Prop Shield lightsaber SFX

    Something I've been playing with lately. It sounds pretty good to my ear but seems like it's missing something. What do you think?

    Cool. Hopefully when you feel you are at a stopping point, you will post the code.

    Sounds much better than my attempt at the same thing. Do you have any random modulation on your hum? I found rolling the base of the hum up and down a bit over a time of a couple of seconds added a bit of life. You can do it on a slow sine, or get a bit more creative and execute a random walk (pick freq, slew to it slowly, pick new random freq within sensibe range). Or get really clever and use perlin noise, either generated or from an array long enough the ear doesn't pick the pattern.

    Your hum is much better than anything I've got so will be interested to see how you constructed that.

    Edit: also impressed you can wave a breadboard around without firing the wires out of it!

    No random modulation on hum. I have some oscillation on the buzz gain (square wave) to give it some depth while not swinging. Using 2 fm sine's(hum) and a square wave(buzz). Thinking I may add another high frequency fm sine for some more depth.
