Ocean Waves generates a simulated sound of ocean waves.

Unlike the recorded sound of ocean waves, the simulated sound of ocean waves does not repeat for hours.

You can save the simulated sound of ocean waves as an audio file (up to 400 minutes), and burn a CD (up to 79.9 minutes with iTunes) or download to your iPod from iTunes.

I hope this helps you relax, sleep at night, and wake up in the morning.

• Timers: Wake up and sleep timers
• Noise generators: Pink noise and brown noise

NOTE: iTunes doesn't accept caf files. On OS X 10.8 and up, you can open the Ocean Waves caf file using QuickTime Player, and export directly to iTunes by choosing "Export To iTunes..." from the File menu. On OS X 10.7 and earlier, you can covert the Ocean Waves caf file to an m4a file using QuickTime Player, then add it to the iTunes Library. To convert, open QuickTime Player, open the Ocean Waves caf file, choose "Export..." from the File menu, save, and drag & drop the saved m4a file onto "LIBRARY" on the iTunes window or choose "Add to Library..." from the File menu in iTunes and select the saved m4a file.

This app does not work

THe application does not work reliably and often plays nothing at all. Have messed with this, and it produces no sounds whatsoever. The link for support is also bogus. STAY AWAY!

Great for concentration or sleeping!

I used this app extensively in college to help keep external noise at bay in the day (roommates) and to help me sleep at night (loud city). It’s the best “white noise” generator I’ve used on the Mac in many years. It combines pink noise and brownian noise (aka brown noise) for a very nice balance of random noise. Most apps will only let you listen to one at a time and usually include true white noise which is very high pitched and annoying. Both pink and brown noise sound lower and are more soothing to listen to.

To help keep external noise from distracting you I suggest turning off the “Amplitude Generator” which will keep the noise level consistent. When you want to relax or feel like you’re on the beach, turn the “Amplitude Generator” back on and feel the waves wash over you :)

It would be great if you could enable and disable this without having to go into the application’s preferences, but it’s not awful.

Must-have Productivity Tool

I bought version 1.0 of this app long ago and was a little annoyed at the thought of spending $1.99 to buy it again. Then I stopped to think about the hundreds of hours of work I have accomplished while gentle, realistic, crashing ocean waves rolled away in the background and hit the “Buy” button. If you enjoy the relaxing sound of ocean waves, stop here. Ocean Waves is the (genius) polar opposite of my second favorite Mac relaxation app, Sonic Mood. Instead of having a hundred possible settings, it has one good one: “Start Ocean Waves.” Together with the awesome option of exporting a core audio format file to take your waves with you wherever you go, you’ll need nothing else. Roll on, Katsura.
