A python wrapper for rnnoise

python wrapper for the rnnoise library.

Prerequisites

• Have rnnoise installed
• python (2/3)
• numpy

Example usage

It operates on RAW 16-bit (machine endian) mono PCM data sampled at 48 kHz.

Each frame of data must be in binary, and must be 480 int16s (i.e 2 bytes per sample.) This translates to 960 bytes per audio frame.

import rnnoise,sys
denoiser = rnnoise.RNNoise()
stream = sys.stdin.buffer
input_data = stream.read(480*2)
va_prob,denoised_data = denoiser.process_frame(input_data)
