Signal Processing and Audio Effects
Audio Effects change the sound by processing the signal in a given way.
Distortion, chorus, flanger, and delay are just some of the ways an audio signal gets processed.
Types of Effects
Audio effects can be placed into one of four categories:
Time - Delays, Multi-Tap Delays, Reverbs, Chorus, Ensemble, Vibrato, Flanger, Phase Shifter, Resonator, Stereo Expader, Pitch Shifter, Intelligent Harmonizer, Doppler Effect (Increase in Pitch to Decrease in Pitch), Octave Divider.
Amplitude - Distortion, Overdrive, Exciter, Tremolo, Panner, Ring Modulator, Compressor, Limiter, Expander, Gate, De-Esser
Frequency - Vocoder, Talk Box, Formant Filter, Wah-Wah, Auto Wah, Graphic EQ, Parametric EQ
Hybrid - Rotary Speaker Simulator, Amp Simulator, Speaker Simulator, Vocal Canceler
Time Effect - Delay
Delay - Is the repeat of a signal source produced. Distance can vary between original sound and delay. Min delay=10 - 20 milliseconds. Max=240 - 250 milliseconds.
Time Effect - Echo
Echo - Is what you hear in very large spaces with reflective walls. Think of the Grand Canyon. Used in particular circumstances. Use it wisely.
