This website contains several hundred sound files. Each application has a few of these that must be downloaded before it will start. This all works best with a quality high-speed connection to the Internet. Although it has been designed to work with a modern smart phone, you'll need a good data connection. If you experience slow download speeds, try using a wifi connection. Thank you for using this free service. We hope you like it, and will consider making a small donation to help support our efforts.
