Filter Node ​

The filter node holds a very basic two pole filter(12dB/oct), it has multiple filter types supported by the Web Audio API with adjustable Gain, Frequency and Q.

Each of the filters can be duplicated and chained in series to create a steeper rolloff filter. For example, to create a classic 48dB/oct rolloff filter, you need to chain 4 of them together.

Filter Types ​

The possible filter types are the following:

• allpass
• notch (band-stop)
• peaking (bell)
• highshelf
• lowshelf
• bandpass (band)
• highpass (lowcut)
• lowpass (highcut)

Notice ​

⚠️ The Q and/or Gain may not have an affect with certain types, and/or certain filters require a Q value of +1 to work as expected.
