Audacity 4.0.1 Free Download for Windows

Important Features

1. Multitrack Recording and Mixing: Capture several sources at once from different inputs, then ride per-track gain, pan, and mute or solo until the balance is right.
2. Non-Destructive Editing with Undo History: Clips can be split, trimmed, moved, stretched, and re-arranged while the original file stays intact, and any step can be rolled back or A/B compared.
3. Low-Latency ASIO on Windows: New in 3.7.9, ASIO support talks directly to your audio interface for shorter round-trip delay, and the playback and recording device choice is now remembered for each host separately.
4. Built-In Effect Chain: Dozens of ready effects cover the everyday fixes, including noise reduction, click removal, equalisation, compression, reverb, and change tempo or pitch, with VST, LADSPA, and Nyquist plug-ins on top.
5. Wide Format Support: Work in WAV, AIFF, FLAC, MP2, MP3, and Ogg Vorbis out of the box, and add FFmpeg 9 to pull audio out of M4A, AAC, AC3, WMA, or video files.
6. Batch Processing: One queue applies the same chain of effects and export rules across a folder of files, which is how fifty interview clips get trimmed and normalised without clicking through them one by one.
7. Repair and Analysis Tools: Find silence, locate clipped samples, notch out a hum, mark beats, and label regions, so podcast editing becomes a search-and-delete job rather than a listening marathon.
8. Open Source and Genuinely Free: Released under the GPL by the Audacity Team, with no upsell screen, no watermark, and no account, while the community keeps pushing fixes and new builds.
