Crowd at a college graduation, you can hear the graduation march being played in the distance and the crowd chatting around you. Recorded on my tascam dr-40.
The ambiance recorded in the crowded cafeteria at siam paragon shopping complex in the heart of bangkok, thailand. Recorded with a cheap omni-directional condenser microphone.
A recording of the crowd at charing cross station. Not much that seperates them from other crowds, but the shape of the space might change the dynamic of the sound a bit. Not sure. Recorded on an iphone.
