Web Audio API
AudioNodeComposite: this is a convenient class for creating a custom composite/wrapping
AudioNodeclass. It is used internally and can be also used for creating your own custom composite/wrapping
AudioNode. As an additional goodie, the class provides a useful
bypass()method for temporarily bypassing the effect of the underlying
AudioNodeLimiter: these are just convenient wrappers for the regular functionality provided by the Web Audio API
DynamicsCompressorNodeclasses, providing the
bypass()functionality and some opinionated parameter defaults.
AudioNodeEqualizer: this is based on the Web Audio API
BiquadFilterNodeclass and provides a convenient multi-band parametric equalizer
AudioNodeMeter: this is based on the Web Audio API
AnalyzerNodeclass and continuously tracks and measures the overall volume in decibel of the audio stream. It is also the internal base building block for the
AudioNodeGate: this is based on the Web Audio API
GainNodeclass and measures the volume in decibel of the audio stream and drains the volume if it drops below a certain decibel threshold. It is intended to act as a Noise Gate.
AudioNodeSpectrum: this is based on
AudioNodeMeterand hence the Web Audio API
AnalyzerNodeclass to analyze the frequency/decibel spectrum of the audio stream and continuously render it in a (linear or logarithmic) scale to a
Canvaselement in the DOM.
AudioNodeVoice: this is based on
AudioNodeLimiterto provide a convenient single
AudioNodewhich acts as a reasonable filter chain for voice. Its opinionated parameters are intentionally hard-coded and are just based on some experiences of the author.
