In digital audio, there are two main concepts that govern the quality of the audio: sample rate & bit depth. As the name implies, sample rate is the rate at which the digital samples are recorded. The higher the sample rate, the higher the maximum frequency the digital system can capture and/or reproduce. But what is bit depth? In this post bit depth and how it applies to audio will explained. By understanding how bit depth affects digital audio you will be able to make better decisions about your sessions resolution.
