Find the highest representable frequency for a sample rate.
Any frequency above half the sample rate cannot be represented and aliases back into the audible band. Choosing a sample rate and its anti-aliasing filter hinges on keeping every wanted frequency below the Nyquist limit.
Nyquist Frequency
Nyquist = sample rate / 2
Nyquist = sample rate / 2 Any frequency above half the sample rate cannot be represented and aliases back into the audible band.
