The sampling frequency (or sample rate) is the number of samples per second in a Sound. For example: if the sampling frequency is 44100 hertz, a recording with a duration of 60 seconds will contain 2,646,000 samples.
Usual values for the sampling frequency are 44100 Hz (CD quality) and 22050 Hz (just enough for speech, since speech does not contain relevant frequencies above 11025 Hz; see aliasing).
