Noise Suppression for Voice

The plugin provides real‑time noise suppression for voice signals using Xiph’s RNNoise library. It supports multiple audio standards—including VST2, VST3, LV2, LADSPA, AU, and AUv3—and operates on 16‑bit, 48 kHz input, handling one or more channels. The built‑in GUI exposes parameters such as VAD threshold and grace periods, allowing users to balance noise reduction against latency.

Target users are developers and audio engineers who need on‑the‑fly background‑noise removal for microphones in environments like offices, homes, or travel. It is suitable for integration with DAWs, system‑level audio pipelines (e.g., PipeWire on Linux, Equalizer APO on Windows), and other host applications that accept the supported plugin formats.

Distinctive aspects include reliance on the open‑source RNNoise algorithm, a minimalistic diagnostic interface, and explicit guidance to maintain a 48 kHz sample rate for correct operation. Configuration examples are provided for both Windows and Linux, and the plugin is released under GPL v3 with a stable maturity level.
