Audacity – A Free Audio Recording & Editing App

by Kim Sternish, Toolfarm

Audacity is a FREE easy-to-use, multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. Whether you’re editing a podcast, external audio for a video, or a voiceover, Audacity can handle it. If you really want to step up your videos, first you need to step up your audio — it makes a noticeable difference. If you’ve never worked with a DAW or edited audio in Premiere Pro, here are a few tips to get you started with Audacity.


  • Recording – Audacity can record live audio through a microphone or mixer, or digitize recordings from other media.
  • Export / Import – Import, edit, and combine sound files. Export your recordings in many different file formats, including multiple files at once.
  • Sound Quality – Supports 16-bit, 24-bit and 32-bit. Sample rates and formats are converted using high-quality resampling and dithering.
  • Plugins – Support for LADSPA, LV2, Nyquist, VST and Audio Unit effect plug-ins. Nyquist effects can be easily modified in a text editor – or you can even write your own plug-in.
  • Editing – Easy editing with Cut, Copy, Paste and Delete. Also unlimited sequential Undo (and Redo) in the session to go back any number of steps.
  • Effects – Real-time preview of LADSPA, LV2, VST and Audio Unit (macOS) effects. Plug-in Manager handles plug-in installation and addition/removal of effects and generators from the menus.
  • Accessibility – Tracks and selections can be fully manipulated using the keyboard. Large range of keyboard shortcuts.
  • Analysis – Spectrogram view mode for visualizing and selecting frequencies. Plot Spectrum window for detailed frequency analysis.
