The Haas Effect

The history of the Haas effect   The precedence or Haas effect has first been discussed back in 1949 in the works of H. Wallach, E. Newman and M. Rosenzweig in their publication named “ The Precedence Effect in Sound Localization”. The authors discussed the...

Phase Shifting & Time Delay

What is Phase shifting?   Phase shifting is essentially in the core of every audio filter or equalizer. For example, all-pass filters are the heart of phase-shifting effects. They can create an artificial stereo from a mono sound source. Flanging effect is...

Grain Delay

Grain Delay Origins   Grain delay effect draws its roots from granular synthesis. It all started in 1946 when a physicist called Dennis Gabor published his work about applying quantum physics methods to the sound signal. With this work, he came up with the system...

Room Reverb

Room vs Hall   Room reverb, as the name suggests, is closely related to a Hall reverb. They are both designed to simulate the natural sound of acoustic spaces. The main difference between them is that rooms are smaller spaces, which means that sounds travel much...

Spring Reverb

Spring Reverb Device   The reverb effect essentially represents a collection of delayed sound repetitions. Bell Labs company invented and patented the original spring reverb device. The reason for its creation was because they wanted to simulate the delays which...

Tape Delay

The History of Tape Delay   The term “echo“ was first mentioned in 1950 when electronic devices came into the recording studios. Back then, producers tried to recreate the acoustic properties of different sound spaces. These devices were referred to as “echo“...
