Methods

loadConvolverKernel(Float32List samples, int channels, int kernelId) → int

loadDdcCoefficients({required List<double> sections44100, required List<double> sections48000, required int sectionCount}) → void

Load DDC biquad-section coefficients. Each section is 5 floats: b0, b1, b2, a1, a2. sections44100 and sections48000 should each have length = sectionCount * 5.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.
