dtln-rs

dtln-rs provides near real-time noise suppression for audio in web browsers.

Built on a Dual-Signal Transformation LSTM Network (DTLN) approach, this module provides a lightweight and portable noise reduction solution packaged as a WebAssembly module with ES module support for easy integration in web applications and WebRTC.

Installation

npm install dtln-rs

Usage

import DtlnPlugin from 'dtln-rs';

const handle = DtlnPlugin.dtln_create();
const input = new Float32Array(512);
const output = new Float32Array(512);

DtlnPlugin.dtln_denoise(handle, input, output);

DtlnPlugin.dtln_destroy(handle);

Build

To build from source:

npm run build

This will compile the Rust code to WebAssembly and generate the necessary JavaScript bindings.

Requirements

• Emscripten (for building WebAssembly)
• Rust toolchain with wasm32-unknown-emscripten target
