I have been adding various game sounds to my library the last few weeks. Some of them are from using coin dropping sounds and music I've created and some have been from recording various coin and arcade machines from a wilmington pizza restaurant/arcade. Fortunately, the owner of the restaurant/arcade allowed me to come in early in the morning before customers and staff arrived to be able to acquire quiet recordings. I used a stereo pair of DPA 4060 mics along with my Zoom F8 recorder to capture the arcade sounds.
Below is a sample of a several of the game sounds that I'm offering for sale as a Bonus Point Pack.
