rnnoise-nodejs

Node.js bindings to Xiph's RNNoise denoising C library.

RNNoise is a project showing how deep learning (Recurrent Neural Networks/RNNs) can be applied to noise suppression.

Install

Use

const rnnoise = require("rnnoise");

const denoisedBufLength = rnnoise.suppress(
  "babble_15dB.wav",
  "babble_15dB_dn.wav"
);

console.log(`Denoised buffer length: ${denoisedBufLength} bytes`);

API

Noise Suppression Functions

rnnoise.suppress(input: string, output: string)

suppress operates on 16-bit RAW audio format (machine endian) mono PCM files sampled at 48 kHz. The output is also a 16-bit RAW PCM file.

• input is a required string of the path to RAW PCM file input.
• output is a required string of the path to output RAW PCM file.
