A downloadable desktop program for Windows and Linux

a looping sound player. add your own favourite noises and blend them to create your ideal ambience.


  • block out irritating background noises
  • create a feeling of being in a particular space, e.g. for meditation or roleplaying
  • create a relaxing atmosphere
  • find a comforting mix of sounds to help you drift off to sleep

getting started

add sounds by clicking "manage sounds". a file manager window will appear and you can add/remove sound files here. you can use the provided sound pack (lull-sounds.zip) or choose your own. you will need to restart lull to see your changes.

lull supports mp3, wav, flac and ogg audio files.

to find more sounds I recommend freesound.org!


I will probably redo the UI for the windows version to make it smaller and simpler!

I'm not sure if a Mac port is possible but I hope to look into it at some point.

I aim to add more sounds to the base sound pack too!


if you experience any issues with lull, please let me know! (twitter, email)
