The flanging effect is an audio effect which combines two audio signals. Because the second signal is somewhat delayed, a swirling effect is produced. The electronic flanging effect is acquired from a natural acoustic phenomenon that occurs when a wide-band noise is perceived due to a combination of a direct and a delayed sound. The…

The chorus effect is created when various individual sounds, with similar pitch and timbre, play at the same time. The chorus audio effect mimics pitch and timing variations, so a single instrument source sound can be perceived as if there were multiple instruments playing in unison. This effect is very common when a group of…

A frequency shifter is a device capable of lowering or raising the frequency of an input signal. This process is achieved by using a technique that involves complex amplitude modulation. The frequency shifter does not maintain a harmonic relationship between the tones and the harmonics found in an input signal. Hence, all sounds that are…

At first, the ring modulator was used for analog telephony. It was employed specifically for frequency-division multiplexing and its target was to carry a variety of voice signals over phone cables. Since the beginning, ring modulators were involved in voice inversions, radio transceivers and in several electronic music effects. Ring modulators began to gain popularity…

Phasing is a popular effect used in electric guitars. A phaser is a modulation effect that includes phasers, flangers and chorus. These effects give the impression of movement and constant change, so modulation refers to as a moment in which a carrier is being altered by a modulator. The carrier is always an audible signal.…

Low-Frequency Oscillation, also known as LFO, is an electronic frequency which usually falls at the far end of the audio range. This frequency typically falls below 20Hz so it’s practically impossible for the human ear to hear it. An LFO is commonly used to create effects that are often used within the electronic music production…
