The name librnnoisevstdll isn't exactly catchy, but it tells us exactly what the file is if we break it down:

In short, librnnoisevstdll is the Windows VST wrapper for the RNNoise library. It acts as a bridge, allowing you to load the powerful RNNoise engine directly into your audio software as a plugin.

Windows audio plugins generally live in specific folders. If you don't have one, create a folder named VST Plugins on your hard drive (e.g., C:\Program Files\VST Plugins). librnnoisevstdll

#include "rnnoise.h"
#include <stdio.h>
int main() 
DenoiseState *st = rnnoise_create(NULL);
if (!st)  printf("Failed init\n"); return 1; 
float noisy[480] = 0;
float clean[480];
// ... fill noisy with 48 kHz mono audio ...
float vad = rnnoise_process_frame(st, clean, noisy);
printf("VAD probability: %f\n", vad);
rnnoise_destroy(st);

cl /I. /Fe:test.exe test.c rnnoise.lib

RNNoise is incredibly lightweight. It was designed for low-latency communication. Unlike some heavy AI plugins that require massive GPUs, librnnoisevstdll runs smoothly on almost any modern CPU, making it perfect for live streaming or live recording.
