pyroomacoustics.multirate module

pyroomacoustics.multirate.frac_delay(delta, N, w_max=0.9, C=4)

Compute optimal fractionnal delay filter according to

Design of Fractional Delay Filters Using Convex Optimization William Putnam and Julius Smith

Parameters:

• delta – delay of filter in (fractionnal) samples

• N – number of taps

• w_max – Bandwidth of the filter (in fraction of pi) (default 0.9)

• C – sets the number of constraints to C*N (default 4)
