What does sampling depth refer to in sound processing?

Sampling depth refers specifically to the number of bits used to store each sound sample in digital audio processing. This characteristic is crucial because it directly influences the dynamic range of the recorded sound, meaning the range between the quietest and loudest parts of the audio. A greater sampling depth allows for more precise representation of the audible sound waves, which translates to higher audio fidelity and less distortion. For example, a sampling depth of 16 bits typically provides 65,536 possible values for each sample, while 24 bits allow for over 16 million values, leading to significantly improved sound quality.

This concept is fundamental in understanding how audio recordings capture nuances in sound, impacting everything from clarity to the overall listening experience. Higher sampling depths are typically utilized in professional music production and sound design to achieve the best quality recordings.
