Ports and connections
| Port / ID | Type | Connection |
|---|---|---|
Audioin | audio | Audio: audio input for Biquad. A source connection is required.Required |
b0 b1 b2 a1 a2coefficients | array | An Array of exactly five values: b0, b1, b2, a1, a2. The a0 coefficient is already normalized to 1.Required |
Outputout | audio | The audio result of Biquad, available to other nodes on every sample.Output |
An output can feed multiple inputs of the same type. An input has one source; Function also requires matching signatures. All connection rules →
Parameters
There are no fixed numeric parameters. Custom nodes, collections and C++ expose additional settings through their definition in the inspector.
How to use it
Input → Audio; Biquad Coefficients → coefficients; Output → Output / Audio.
Things to check
Exactly five coefficients are required. Arbitrary unstable coefficients can produce invalid DSP.
Check required inputs and matching types. Run Compile before auditioning; a validation failure preserves the previous working module. Troubleshooting →
