Client-Side Noise Suppression Library

Datadog developed and open-sourced dtln-rs, a real-time, client-side noise suppression library based on the Dual-Signal Transformation LSTM Network (DTLN). This library is designed to be embeddable in native clients and web applications, offering high performance without server dependencies. It leverages WebAssembly, Node.js native modules, and native Rust targets to integrate with WebRTC, enabling high-quality audio processing directly on the client device. The implementation focuses on optimizing STFT, phase information, and LSTM neural networks for efficient, real-time noise reduction.
