Vinyl Restoration Suite is a free audio restoration plugin and standalone application for Windows, macOS, and Linux. It detects and repairs clicks and pops using crossfade and spline interpolation, and reduces noise with real-time FFT processing that can capture a noise profile. Its AI denoiser is based on RNNoise and supports DirectML and NPU acceleration. A 10-band graphic equalizer covers 31 Hz to 16 kHz, while separate filters address subsonic rumble from 5–150 Hz and AC power line hum from 40–80 Hz. The app can record audio and split tracks automatically at silence. Real-time waveform and spectral views help monitor audio, and Difference Mode plays the noise and clicks being removed. Use it as a VST3 plugin in a DAW or independently as a standalone app. Pre-built binaries are listed for all three desktop systems; the macOS DMG is described as universal for Intel and ARM. It is available under the MIT license at free.
