Generate center frequencies and sample rate pairs.
This function will return center frequency and corresponding sample rates to obtain similar pitch filterbank settings as described in . Instead of starting with MIDI pitch A0, we start with C0.
- tuningfloat [scalar]
Tuning deviation from A440, measure as a fraction of the equally tempered semitone (1/12 of an octave).
- center_freqsnp.ndarray [shape=(n,), dtype=float]
Center frequencies of the filter kernels. Also defines the number of filters in the filterbank.
- sample_ratesnp.ndarray [shape=(n,), dtype=float]
Sample rate for each filter, used for multirate filterbank.
This function caches at level 10.
