Sample Rate
The sample rate is the number of times an analog signal is measured—or sampled—
per second. You can also think of the sample rate as the number of electronic
snapshots made of the sound wave per second. Higher sample rates result in higher
sound quality because the analog waveform is more closely approximated by the
discrete samples. Which sample rate you choose to work with depends on the source
material you’re working with, the capabilities of your audio interface, and the final
destination of your audio.
For years, the digital audio sample rate standards have been 44,100 Hz (44.1 kHz) and
48 kHz. However, as technology improves, 96 kHz and even 192 kHz sample rates are
becoming common.
