Here's a recording of somewhat heavy rainfall recorded toward the end of a storm. Occasionally subtle birds can be heard through the rain, especially when the rain calms a bit at times. Rain is often a preferred sound for relaxing, sleeping, and meditating because it occurs in nature, is calming, and masks sounds well due to its large coverage of the sound spectrum (similar to white noise, pink noise, and brown noise).
Virtual Crickets is the ambience and white noise focused pseudonym of Hayden Davenport, a freelance video game composer also known as Lo-Phi. The music posted here is entirely for sleep, study, relaxation, meditation and/or focus.
