about

the twetieth synthesis techniques challenge - In this weekly series we'll explore the myriad of ways one can synthesize sound.
This week, we're covering something i use daily and you should too: digital noise! digital noise is effectively random pulse waves, but there's a lot of ways to create that and they all sound different. The easiest would be to put a comparator on a noise source, creating a random pulse train. This would be excellent, except most people don't have basic utilities like comparators in their rack. You can also sum 6-8 highly detuned pulse waves, which is how old drum machines made the noise required for cymbals... but most people don't have 6 spare oscillators. Most people do have a shift register in their rack, however, and those can also spit out a random pulse train when clocked at audio rate. Bonus points for using a linear feedback shift register! If you don't have any of that, you can also run noise through an extremely heavy distortion. This will create a hard clipped noise, which is similar to random pulses. Feel free to experiment with other ways to make random square waves! I would prefer we focus on creating the sound this time, so minimal/no modulation and effects please. Have fun, and I'll have a new one next Friday!
