But it's not resolution, right? It's extra frequencies outside the audible range. Is there any natural process that would make those affect the audible components, if I were listening to the music live instead of a recording?
- sitharus 9y agoYes, you can get a beat effect (https://en.wikipedia.org/wiki/Beat_(acoustics) https://en.wikipedia.org/wiki/Beat_(acoustics)) as the ultrasonic frequencies interfere with the audible ones. It's generally not considered desirable.
- kazinator 9y agoOnly if the two are mixed in a nonlinear way (e.g. "heterodyned"). If a sonic and ultrasonic frequency are combined together, but a low pass filter doesn't pass the ultrasonic one, the ultrasonic one doesn't exist on the other end. Hence, there can be no beat.
