Convolution

upols_convolver

Uniformly partitioned overlap-save convolver.

sparse_upols_convolver

Uniformly partitioned overlap-save convolver with a sparse frequency delay line (FDL) on the filter.

Frequency Delay Line

• dense (mdarray)
• sparse (csr_matrix)
• sparse static mixed bit-depth (Nx csr_matrix, fixed non-overlapping slices)
• sparse dynamic mixed bit-depth (Nx csr_matrix, overlapping slices)
• sparse adaptive dynamic-depth (individual scalar for each FDL row)
