I grew up on clean, digitally produced music. Maybe lo-fi is just a fad but I love the character of lo-fi music.
I’m also completely in-the-box. Here’s some of what I do:
Convolution reverb. It’s a magical one-stop tool for changing the surrounding source and space of a sound. Get a decent recording of a loud noise in your favorite stairwell, your favorite speaker, your bedroom, etc. Trim it a bit if you’d like. Then use that as your impulse, and every sound you put through it will have the echoes and frequency response of that impulse.
You can also use this to smear sounds into ambient bliss
recommended impulse collections for the experimenters out there:
Unnatural spaces - echoes in small objects
The Threshold - funky impulses that destroy everything in a beautiful way
Shiru’s lofi impulse pack - IRs of cheap speakers
Any samples of cymbals, gongs, drums, or other percussive sounds (maybe something from disquiet0433 if the license allows) - try it out!
Databending. Usually more FSU and less lo-fi but you can find a balance if you look for it.
It would take a long time to fully explain the ideas and processes but I learned starting from these two sites: Intelligent Machinery and stAllio!'s way
also gotta mention Tesselode’s Flutterbird - wow/flutter effect. It’s simple but it works
