PRUDHOMME2020 - Compute the effective SNR taking into account harmonic cancellation

Usage

[predicted_SNR] = prudhomme2020(target,targSpec,masker,meanf0,fs, jitter,fc_target)

Input parameters

target target
targSpec target spectrum
masker masker
meanf0 mean fundamental frequency [Hz]
fs sampling frequency [Hz]
jitter jitter
fc_target center frequency of the target [Hz]

Output parameters

wSNR weighted Signal-to-Noise Ratio

Description

PRUDHOMME2020 is a monaural model computing the effective SNR taking into account harmonic cancellation. It takes the target and interferer signals (sampled at fs) as input, along with the masker F0 and jitter info
