I once listened to a podcast where fourier transforms were used to generate sounds that otherwise don't exist.

Could you maybe share which podcast? Generating “sounds that otherwise don’t exist” does not sound particularly remarkable taken at face value. It’s basically what any synthesizer or audio processor does, and Fourier transforms are also a very commonly used in audio processing.

This podcast. The episode of Joseph Fourier.

What I meant by "sounds that otherwise don’t exist" are sounds that are too complex to be created by physical music instruments its easier to simulate them by computer.

> sounds that otherwise don’t exist.

hmmm
