Sound waveMeasurementof amplitude

Sample is a single measurement of amplitude.

Minimum sampling rate should be at least twice the highest data frequency of the analog signal.

The larger sampling rate, the better accuracy of conversion

Encoding samples

Each sample is assigned a number according to its amplitude.
