Modulation Effects Part 2

“Modulation Effects Part 2” is a continuation of our first entry on this topic. In particular, modulation effects modify sounds in a peculiar way. Moreover, they can also alter sounds in a dramatic and bizarre manners. Many advanced effects have been available to the public for years, but recently, they’ve gained popularity especially in contemporary…

Modulation Effects (Part 1)

Modulation effects are a type of audio effect that modify sounds in a peculiar way. You can alter sounds with modulation effects by adding a time-delayed version of the sound itself while varying the size of that delay over time. In general, modulation provides a sense of dimension, motion, and depth. Modulators, also known as control…

Flanging Effect

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

Chorus Effect

The chorus effect occurs when various individual sounds, with similar pitch and timbre, play at the same time. It mimics pitch and timing variations, so an audience can perceive a single instrument source sound as if there were multiple instruments playing in unison. This effect is very common when a group of singers or violinists,…

Rotary Speaker

Donald Leslie created and manufactured the rotary speaker, which people also know as the Leslie speaker. This device refined the sound of the Hammond Organ and revolutionized electronic music. Leslie also invented a special speaker which intended to improve the sound of the Hammond Organ. This speaker rotated itself inside its own cabinet. The Theater…

Frequency Shifter

A frequency shifter is a device that lowers or raises the frequency of an input signal. Engineers achieve this process by using a technique that involves complex amplitude modulation. This shifter does not maintain a harmonic relationship between the tones and the harmonics found in an input signal. Hence, all sounds that are processed by…

Ring Modulator

At first, people employed the ring modulator for analog telephony. Specifically, they used it for frequency-division multiplexing. Its target was to carry a variety of voice signals over phone cables. Since this start, ring modulators were part of voice inversions, radio transceivers, and several electronic music effects. Ring Modulator: Its Context Ring modulators began to…

Phaser

A phaser is a modulation effect that includes phasers, flangers, and chorus. Phasing is a popular effect in electric guitars. These effects give the impression of movement and constant change. In this sense, modulation refers to as a moment in which a modulator alters a carrier. This carrier is always an audible signal. These three…

Low-frequency Oscillation (LFO)

Low-Frequency Oscillation, also known as LFO, is an electronic frequency that 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. Experts commonly use an LFO to create effects within the electronic music production universe. Low-frequency oscillation creates…
