A linear phase is a property of a filter where the phase response of the filter is a linear function of frequency. As a result, the entire input signals of the frequency are moved at the same time by the same constant amount, so there is no phase distortion. This is known as group delay.…

A/B Stereo Recording Technique

The A/B stereo recording technique, also known as Spaced Pair, is designed to capture the same sound source through the two microphones they have within. These mics are located from a range of three to ten feet apart from each other, which allows them to create time-of-arrival (phase), and level (amplitude) differences from the input…
