Actual foghorn of detour reef lighthouse in upper peninsula, michigan. Starts loud then gets quieter as the compressed air runs out. Recorded with a sony pcm.
Sound generated with buzz generator in audacity, added some reverb to make sound it like in open air. Usable in games for some ship models if you want.
Atmo of a boat trip in the harbour of hamburg. Mostly wind sounds, but you can hear the ship motor and some voices as well. Recorded on a zoom h5 with x/y-head.
