According to Nyquist's work, you need a sample rate of 2f to represent a frequency f.
So with 44.1 kHz you could only represent audio up to 22 kHz. There are kids who can hear at these frequencies.
- Cyph0n 10y agoI am aware of the Nyquist rate. You're talking about very rare edge cases though. I believe the cut-off for an average young human is 20 kHz.
- macawfish 10y agoYeah, I get that, just saying, if we are going to worry about people with disabilities, I believe that we should care about the psychoacoustic wellbeing of "edge case" humans who can hear ultrasonic tones.
- Cyph0n 10y agoSo you're comparing disabilities, like not being able to walk or see, to a slightly annoying tone? Of course, it also depends on the estimated number of "edge cases" out there.
- colanderman 10y agoAnd even then, you need a few kHz bandwidth for the low-pass filter. Those high frequencies are greatly attenuated.
