Sample rate to Bit rate

We looked previously at the sampling theorem and the way that affects the frequencies which can be represented. Since the advent of audio compression algorithms all the talk has been about bit rate. Today we’ll look at these two terms … Continue reading

Two views of audio

There are two views, or domains, in which audio must be viewed to make any sense of it. Firstly, the time domain. This is the most common way of thinking of audio. Sampled audio is a time domain representation of … Continue reading
