What Tsunami is

Tsunami is a free, GPL-3.0 open-source digital audio workstation for Linux, Windows, and macOS. It was mainly developed for personal home recording and includes multitrack mixing, multi-version recording, audio effects, synthesizers, samples, signal chains, MIDI editing, sequencing, and persistent sessions. Its plugin system uses a dedicated language and just-in-time compiler, allowing plugin classes such as audio effects; it supports x86_64 and aarch64 processors. Tsunami began as a Linux project, with build instructions requiring GTK 4, zlib, and FFTW3 and recommending PulseAudio and ALSA. Windows support is described as experimental and uses Visual Studio 2022 instructions. macOS support is also experimental: installation is unsupported, while an app bundle can be built. Repository documentation covers building, running, plugins, internal design, and development, but the usage guide currently says “TODO.”

Who it suits

Tsunami fits people seeking a free workstation for home recording, multitrack audio, MIDI work, and extensible plugins. Platform support is available across Linux, Windows, and macOS, with experimental status on Windows and macOS.

What it does well

  • Free and open-source under GPL-3.0
  • Multitrack mixing and MIDI editing
  • Effects, synthesizers, samples, signal chains
  • Persistent sessions for continuing work
  • Plugins support x86_64 and aarch64

What to know first

  • Windows support is experimental
  • macOS installation is unsupported
  • Usage guide currently says “TODO”
