Quietly capable.

Nullwave stays out of the way until you need it, then remembers exactly how you like every sound.

Your sound, your volumes

Each sound remembers its normal level and, when enabled, a second level for when another app is playing audio. Nullwave lowers and restores itself smoothly.

Three favorites. Right there.

Choose up to three sounds for the menu-bar panel. Reorder them whenever your routine changes.

Preview without disruption

Explore another sound, then stop the preview or leave its page. Nullwave returns to what you were hearing before.

Controllable from the command line

Play, stop, switch sounds, and set Nullwave’s independent volume without launching another copy.

$ nullwavectl noise brown
$ nullwavectl volume 25

Native, thoughtful, small

A good Mac citizen.

Nullwave is a true native menu-bar app. It launches at login when you ask, uses the system accent color, follows light and dark appearance, and generates audio locally.

  • Headset call-mode detectionOptionally pauses when the same device handles input and output, then resumes afterward.
  • Generated locallyEvery sound is created in real time on your Mac, with no audio files or loops.
  • Adaptive volumeOptionally lower each sound while another app plays, without changing your Mac’s system volume.

Make some room to think.

Free, private, and ready for your menu bar. No account required.
