How it works: Active sounds loop continuously. The ramp raises volume slowly from 5% to your master volume setting. Press Stop when finished — no automatic cutoff in the free version.
Free version includes: Thunder, Fireworks, and Dogs Barking.
Full version ($12) adds Gunshots, City Traffic, Sirens, Crowd Noise, Jackhammer, session timer, adjustable start intensity, and custom sound recording.
