Linear Phase Equalizers

Linear phase equalizers have the most transparent sounding types of equalization. However, before delving into how they operate, we must understand its physics—which is where the name comes from. 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…

Binaural Sound

Stereophonic sound recording was first known as a binaural sound—and it all started with a talkie at a local cinema. A talkie was an early sound film that used a single speaker. When Alan Blumlein first discovered this device, he realized there was a way to follow the actors across the screen. This was the…

A/B Stereo Recording

The A/B stereo recording technique, aka Spaced Pair, captures the same sound source through the two microphones it has within. These mics are located from a range of three to ten feet apart from each other. In turn, the separation creates time-of-arrival (phase) and level (amplitude) differences from the input they receive. As they get…
