clarity.enhancer.nalr module

class clarity.enhancer.nalr.NALR(nfir: int, sample_rate: float)

Bases: object

apply(nalr: np.ndarray, wav: np.ndarray) → ndarray

Parameters:

• nalr – built NAL-R FIR filter

• wav – one dimensional wav signal

Returns:

amplified signal

build(audiogram: Audiogram) → tuple[ndarray, ndarray]

Parameters:

• hl – hearing thresholds at [250, 500, 1000, 2000, 4000, 6000] Hz

• cfs – center frequencies of the hearing thresholds. If None, the default values are used.

Returns:

NAL-R FIR filter delay
