Audacity is a desktop multi-track audio recorder and non-destructive editor with built-in effects (noise reduction, EQ, reverb, echo) and spectrogram analysis. It imports, exports and converts common formats like MP3, WAV, FLAC and AIFF, and supports VST3 and Nyquist plugins, with LV2 on Linux and Audio Units on macOS.
It is entirely free and open source, with no paid tier or feature gating. It fits a solo podcaster or content creator recording and cleaning up voice audio on a desktop, though it lacks MIDI editing or virtual instruments, and has no official mobile app.

Against. What to plan for.

Permanent free plan
Fully free and open source with no feature restrictions
Audacity remains a free open-source audio editor with no native AI, but third-party plugins (noise removal, transcription) are starting to attach to it without changing its philosophy as a manual, lightweight tool.
Can AI replace it?
Replace Audacity with an AI? No: manually editing audio (cutting, mixing, adjusting) remains a skill AI assists via plugins without fully replacing it. Verdict: AI augments certain technical tasks, manual editing remains possible and free.
