Amount of times the program converts analog to digital per second.
In digital audio, an analog continuous wave is "sampled" to discrete values. The sampling happens many times per second. In 16bit audio these discrete sample values represent values between -32768 and 32767. Each sample value represents the Amplitude value of the wave at that specific point.

In digital audio, an analog continuous wave is "sampled" to discrete values. The sampling happens many times per second. In 16bit audio these discrete sample values represent values between -32768 and 32767. Each sample value represents the Amplitude value of the wave at that specific point.
