I was under the impression that the #BMW “piped in engine sound” that has been a thing since the F3x/F8x generation (2013+) was actually amplifying sound taken from a microphone, but it turns out that the sound is entirely synthetic, simulated based on the engine RPM and other parameters using a dedicated amplifier that I assume is then mixed in with the rest of the audio system.

I know this because it turns out you can select which engine’s sounds you want to emulate using Bimmercode.
