  • Delay creates a repeated echo of the original sound that decays over time
    • Achieved by recording an input signal to an audio storage medium and playing it back after a period of time
    • Includes simple single-tap delays to more complex multi-tap and rhythmic delays
  • Delay time determines the time between the original sound and the delayed sound (quarter notes, eighth notes)
  • Feedback controls the number of repeats by sending a portion of the delayed signal back into the delay input
    • Higher feedback settings result in more repeats that decay over a longer period
  • Mix control adjusts the balance between the original dry signal and the delayed wet signal

Modulation Effects

  • creates a sweeping, jet-like sound by mixing a slightly delayed signal with the original
    • Achieved by applying a very short delay time (typically 1-20ms) that is modulated by an LFO
    • Results in constructive and destructive interference, creating peaks and notches in the
  • produces a similar sweeping effect to flanging but with a more subtle and ethereal character
    • Achieved by splitting the signal into two paths and applying an all-pass filter to one path
    • The phase-shifted signal is then mixed back with the original, creating a series of peaks and notches
  • simulates the effect of multiple voices or instruments playing the same part with slight variations
    • Achieved by mixing one or more delayed and pitch-modulated versions of the signal with the original
    • Delay times for chorus are typically longer than flanging (20-50ms) with subtle pitch modulation

Spectral Effects

Pitch and Time Manipulation

  • Pitch shifting alters the pitch of a sound without changing its duration

    • Individual grains can be processed, rearranged, and layered to create unique textures and soundscapes
    • Offers creative possibilities for sound design, transitions, and abstract musical elements

Vocoding and Formant Manipulation

  • (voice encoder) analyzes the frequency content of one signal (modulator) and applies it to another (carrier)
    • Typically used to apply speech characteristics to a synthesizer or other instrument
    • The modulator is divided into frequency bands, each band controls the amplitude of the corresponding band in the carrier
  • allows for independent control of the frequency content (formants) and pitch of a sound
