Best Open-Source Audio Editors 2026: 6 Options Compared

Audacity is the name everybody reaches for, and for plain waveform editing it is still the safe answer: it is GPL-licensed, runs on Windows, macOS and Linux, and has more tutorials than any other editor on this list. The reason to look further is usually one of three things. You may dislike the direction the project has taken and want a community fork, which is what Tenacity is. You may want editing inside a full multitrack recording environment, which points to Ardour or Qtractor. Or you may not want a graphical editor at all, in which case SoX does conversions, trims and effects from the command line and slots into scripts. Kwave is a smaller graphical sound editor aimed at Linux and KDE users. Be honest about what you are doing before choosing. Cutting a podcast or cleaning a voice recording needs a destructive waveform editor with noise reduction, not a digital audio workstation, and the extra concepts of a DAW will slow you down. Mixing ten tracks with automation is the opposite case. One practical trap is the Linux-only tools: Qtractor and Kwave are described by their projects as Linux software, so Windows and Mac users should start with Audacity or Tenacity. Also note that Ardour's source is free but its pre-built downloads are paid, so check that before assuming it costs nothing.
