Install plugins through MuseHub, validate them in Audacity, and use them as realtime effects on a track or the master, or as one-off destructive edits — with the formats Audacity 4 loads, the mistakes that make a plugin ‘not work’, and free plugins to start with.
Audacity gets five AI tools — noise suppression, stem separation, transcription, music generation and audio upscaling — through the free OpenVINO AI Tools plugin. Here is what each one does, where to find it, and how to install it from MuseHub.
Remove hum, hiss and room noise in Audacity 4 — the three-step Noise reduction effect, what each slider does, denoiser plugins that run live on the track with no noise profile, the AI route that still needs Audacity 3, and the noises none of them can fix.
Ten free audio editors that are genuinely free — for Windows, Mac, Linux and mobile. What each one is best at, where the free tiers hide limits, and how to extend a free editor with plugins.
Digitize your vinyl with free software — which of the three hardware setups you have, why a phono preamp matters, the Audacity 4 settings that matter, and how to split a side into individual tracks.
