FftConvolver class

Reusable FFT-based convolution context for repeated calls.

Use this class when the same xMax/hMax configuration is reused across many calls; it keeps a single native context and internal buffers.

Constructors

FftConvolver({required int xMax, required int hMax}): Creates a reusable convolver with maximum input lengths xMax and hMax.

outLenFor(int nx, int nh) → int: Returns the output length for an input of size nx and kernel size nh.
process(Float32List x, Float32List h, {ConvMode mode = ConvMode.convolution}) → Float32List: Computes convolution/cross-correlation and returns a newly allocated output.
processInto(Float32List x, Float32List h, Float32List out, {ConvMode mode = ConvMode.convolution}) → int: Computes into caller-provided out to avoid allocating a fresh output.
toString() → String: A string representation of this object.
