Audacity offers AI plugins powered by OpenVINO for audio editing workflows such as transcription, noise reduction, and music separation. It extends the free Audacity audio editor with local AI-assisted audio processing features.
Audacity is a free, open-source Audio Editing tool that brings local AI-powered effects—including music separation, noise suppression, transcription, and music generation—to its multi-track audio editor through OpenVINO-accelerated plugins, with pricing that remains 100% free. It targets podcasters, musicians, content creators, educators, and audio engineers who want offline AI processing without subscription fees.
Originally launched in 2000 and now stewarded by Muse Group since 2021, Audacity is one of the most widely adopted audio editors in the world, with over 100 million downloads across Windows, macOS, and GNU/Linux. The OpenVINO AI plugin suite, released in 2024, introduces five distinct AI-driven effects directly into the desktop editor: Music Separation (splitting tracks into Drums, Bass, Vocals, and Other Instruments stems), Noise Suppression (optimized for spoken word audio), Music Generation and Continuation (powered by Meta's MusicGen LLM), Whisper Transcription (using OpenAI's Whisper model with subtitle export support), and Audio Super Resolution (upsampling low-quality recordings such as 8kHz telephone calls to higher fidelity). All processing runs locally on the user's machine, leveraging Intel's OpenVINO toolkit for hardware-accelerated inference on CPUs, GPUs, and NPUs.
Based on our analysis of 870+ AI tools, Audacity stands out as one of the very few audio editors that delivers professional-grade AI features entirely free and offline. Compared to subscription-based competitors like Descript ($12-$24/month), Adobe Audition ($22.99/month), or LANDR Studio, Audacity requires zero recurring fees and never sends user audio to the cloud. The trade-off is a steeper learning curve, a dated interface compared to modern web-based editors, and the need to manually install the OpenVINO plugin bundle separately from the main installer. For users who prioritize privacy, ownership, and cost over polish, the OpenVINO release transforms Audacity into a serious AI-augmented production tool that competes with paid alternatives at every level.

Splits a mono or stereo mix into four individual stems—Drums, Bass, Vocals, and Other Instruments—directly inside Audacity's track view. This enables remixing, karaoke creation, sample extraction, and isolated stem editing without exporting to a separate tool like Spleeter or LALAL.AI. All processing is local, so unreleased masters never leave the user's machine.
Uses OpenAI's open-source Whisper model to transcribe spoken audio into a label track aligned with the waveform. Users can export these labels as subtitle files for direct use in video editors, replacing paid services like Otter.ai or Rev for many workflows. Multilingual support is inherited from the underlying Whisper model.
AI-driven background noise reduction optimized specifically for spoken-word recordings such as podcasts, interviews, and voiceovers. Unlike traditional spectral noise gates, the model learns to separate voice from non-voice content, producing cleaner results on hum, hiss, room tone, and environmental noise. Operates entirely offline through OpenVINO inference.
Integrates Meta's MusicGen LLM to generate original musical snippets from text prompts or to extend an existing audio clip with a stylistically consistent continuation. Useful for sketching ideas, filling transitional gaps, or producing royalty-free background music. Output length and quality depend on local hardware capability.
Upsamples low-sample-rate audio—such as 8kHz telephone recordings or archival material—to higher fidelity rates suitable for modern playback and broadcast. The model reconstructs plausible high-frequency content rather than simply interpolating, recovering clarity and intelligibility. Particularly valuable for podcasters working with phone-call guests or historians restoring legacy recordings.

The OpenVINO AI plugin suite continues to expand the free Audacity editor with five locally-run AI effects—music separation into stems, AI noise suppression, MusicGen-powered music generation and continuation, OpenAI Whisper transcription with subtitle export, and Audio Super Resolution for upsampling low-bitrate recordings—delivered through dedicated Windows and macOS installers separate from the main Audacity download.
