Audio Processing concepts:
- Delay: Apply a time delay or echo to a sound. Delay effects typically blend the original audio with delayed audio using a mixer. Delay effects sometimes also have a feedback function, which allows for the sound to repeat itself over and over, producing a reverb-like effect.
- Reverb: Simulates reverberation. Gives a sound a sense that it is occupying a space, like a concert hall. Reverbs can be physical (as in an echo chamber), electromechanical (as in a plate reverb or spring reverb), or electronic (through analog or digital signal processing).
- Compression: Changes the dynamic range of a sound. Compression can “lift” the quieter parts of a sound, reducing the dynamic range and making all parts of a sound louder and more present. While some compressors “color” the sound, typically the goal is to increase the loudness and presence of a particular sound without clipping or distorting the sound. Compression effects typically have an attack and decay setting, allowing you to change the sustain of transients.
- Distortion: intentionally clipping or altering the shape of a sound with gain, with the goal of ampilfying or adding harmonic information. Distortion effects rely on different methods of driving a signal to generate different clipping characteristics, such as using vacuum tubes or Germanium transistors.
- Filters/Equalizers: Cutting or amplifying different parts of the frequency range. A “wah wah” style effect changes the frequency that is being cut according to an expression pedal.
- Chorus/Flanging: Creates a “doubled” effect by applying a very fast delay. The delay time can be modulated to create a “shimmering” effect.
-
Tremolo/Vibrato: Like an LFO, modulating the volume (Tremolo) or pitch (Vibrato).
