Effects

Chorus

Description:

• Creates a multiple copies of a signal, varying its pitch and then mixing the modulated copies with the original signal

Parameters:

• Delay time: Number of seconds from input signal to be storage and play back
• Depth: Length of the effect
• Feedback: The return of a portion of the output signal back into delay loop
• Speed: Frequency of oscillator that makes change in delay time

Code:

• chorus.js

Input-output type:

• Input & Output

Delay effect

Description:

• Multi-node effects in which an audio signal is recorded, reproduced at a time delay, then mixed with the original (main different from "Delay" module), non-delayed signal to create a variety of effects

Parameters:

• Wetness: Loudness of signal with full amount of an effect
• Delay time: Number of seconds from input signal to be storage and play back
• Feedback: The return of a portion of the output signal back into delay loop

Code:

• delayEffect.js

Input-output type:

• Input & Output

Distortion

Description:

• Multi-node effects in which waveform is deformed (clipped) creating a distorted or "dirty" signal

Options:

• Clipping type: Type of clipping

Parameters:

• Gain: Multiplication of sound volume
• Precut: Pre-distortion bandpass filter frequency
• Drive: Overdrive amount. Only in soft clipping
• Postcut: Post-distortion lowpass filter cutoff frequency

Code:

• distortion.js

Input-output type:

• Input & Output

Flanger

Description:

• Blends the signal with a copy of that signal at a slight time delay, then modifying the delayed copy, creating a "swirling" sound

Parameters:

• Delay time: Number of seconds from input signal to be storage and play back
• Depth: Length of the effect
• Feedback: The return of a portion of the output signal back into delay loop
• Speed: Frequency of oscillator that makes swirling sounds

Code:

• flanger.js

Input-output type:

• Input & Output

Reverb

Description:

• Creates persistence of sound after the sound is produced

Options:

• IR list: Different types of preloaded IR

Parameters:

• Dryness: Loudness of signal without any signal processing
• Wetness: Loudness of signal with full amount of an effect

Code:

• reverb.js

Input-output type:

• Input & Output

Tremolo (Gain)

Description:

• Makes a rapid shift in amplitue thus creating "shaking" musical effect

Parameters:

• Speed: Frequency of oscillator that makes trembling effect

Code:

• gainTremolo.js

Input-output type:

• Input & Output

Tremolo (Panner)

Description:

• Makes a rapid shift in pan thus creating "shaking" musical effect sliding from left to right channel

Parameters:

• Speed: Frequency of oscillator that makes trembling effect

Code:

• pannerTremolo.js

Input-output type:

• Input & Output

Vibrato

Description:

• Regular, pulsating change of pitch

Parameters:

• Width: Width of the sine wave used in vibrato. More make the sound more distorted
• Speed: Frequency of oscillator that makes change in simulated periodic variations of pitch

Code:

• vibrato.js

Input-output type:

• Input & Output

WahWah

Description:

• Altering the resonance of musical notes to extend expressiveness, sounding much like a human voice saying the syllable wah

Parameters:

• Speed: Frequency of oscillator that change bandpass inital frequency
• Q: Controls the width of the band. The width becomes narrower as the Q value increases
• Depth: Depth of the bandpass change from oscillator

Code:

• wahwah.js

Input-output type:

• Input & Output
