vs

Before distributing a song, most independent artists need to trim, normalize, remove noise, or otherwise clean up a recording. You don't need expensive software for that — these two free editors genuinely get the job done.

Audacity

Audacity is free and open-source, with a huge community and endless tutorials. It supports full multi-track recording and editing — record several instruments or microphones separately and mix them together — plus a wide range of plugin formats (VST, LV2, LADSPA). The tradeoff is its interface, which feels dated, and most effects work on an apply-listen-undo cycle rather than a live preview.

Ocenaudio

Ocenaudio is free (though not open-source), with a clean, modern interface and one standout feature: real-time preview — you hear an effect change as you adjust it, instead of applying it blind and undoing if it's wrong. It handles large files smoothly. Its tradeoff is that it's built around single-track editing, not multi-track recording or mixing.

Both are legitimate, real tools — not a trick to push you toward a paid app. Pick Audacity if you're recording multiple tracks or instruments and want to mix them yourself. Pick Ocenaudio if you just need to clean up, trim or normalize an already-mixed recording quickly. Either way, once your track is edited and exported, the next step is getting it out into the world.
