The Audio Equalizer (3-Band) node allows you to adjust the bass, mid, and treble frequencies of an audio waveform. It applies three separate filters: a low shelf for bass, a peaking filter for mids, and a high shelf for treble. Each band can be independently controlled with gain, frequency, and bandwidth settings.

Inputs

ParameterDescriptionData TypeRequiredRange
audioThe input audio data containing the waveform and sample rate.AUDIOYes-
low_gain_dBGain for Low frequencies (Bass). Positive values boost, negative values cut. (default: 0.0)FLOATNo-24.0 to 24.0
low_freqCutoff frequency for Low shelf filter in Hertz (Hz). (default: 100)INTNo20 to 500
mid_gain_dBGain for Mid frequencies. Positive values boost, negative values cut. (default: 0.0)FLOATNo-24.0 to 24.0
mid_freqCenter frequency for the Mid peaking filter in Hertz (Hz). (default: 1000)INTNo200 to 4000
mid_qQ factor (bandwidth) for the Mid peaking filter. Lower values create a wider band, higher values create a narrower band. (default: 0.707)FLOATNo0.1 to 10.0
high_gain_dBGain for High frequencies (Treble). Positive values boost, negative values cut. (default: 0.0)FLOATNo-24.0 to 24.0
high_freqCutoff frequency for High shelf filter in Hertz (Hz). (default: 5000)INTNo1000 to 15000
Note: The low_gain_dB, mid_gain_dB, and high_gain_dB parameters are only applied when their value is not zero. If a gain is set to 0.0, the corresponding filter stage is skipped.
