Urban morning birds singing in the distance with a few crows
Suburban air tone with a dog and plane and voices
Crowd in a bar or pub reacting with an expectant cheer
Sound design atmosphere dark powerful and modulating drone
Fast passenger train passes through open air station
Fast freight train passes through open air station, rattling noises, metal squeaks
Restaurant cafeteria ambience with the sound of people
Busy crowd in cathedral. Many reverberant footsteps and low murmur.
