Sampling rate

This value shows how many times per second the data is sampled (recorded). For example, music CDs use a sampling rate of 44.1 kHz, so the sound is sampled (recorded) 44,100 times per second.

The higher the sampling rate, the higher the sound quality, but also the larger the volume of data.
