The EqualizerNode collects audio data from all of its inputs and applies several filters to it before passing it along to its outputs, allowing the user to control the loudness of frequencies in specific ranges.
Common Uses
- Controlling volume of specific frequencies for either a single sound or several sounds at once
Using the EqualizerNode
The EqualizerNode controls volume for five separate frequency ranges. The LowPassGain value adjusts the volume of frequencies below 80 Hz; HighPassGain adjusts volume above 5000 Hz; Band1Gain adjusts the volume of frequencies in a band centered at 150 Hz; Band2Gain adjusts the band centered at 600 Hz; and Band3Gain adjusts the band centered at 2500 Hz.
All five properties can be smoothly changed over time using the InterpolateAllBands method.
