Remote SPL Viewer works with SPL modules in AudioTools, to allow viewing SPL data that is being collected on one ore more iOS devices.
To begin, open the iOS device that you wish to use to send SPL data, and navigate to SPL Traffic Light or SPL Graph. On the setup page for those modules, there is a place to purchase a subscription for 1, 5, or 12 devices to send data simultaneously. Once subscribed, you will receive an ID number that can be entered in the Account Key field. All devices on the same subscription (up to the limit) will be shown on the viewer.
The dev-account is a public demo, connect to it in the viewer below and see if any data is currently streaming. If you have subscribed to Remote SPL Logging in the app, use the ID that is provided there for the Account Key.
