AudioTools Wireless is an app that acts as a wireless transmitter to send the microphone audio to AudioTools running on another iOS device, using the local LAN. It also functions as a remote Generator, controlled by the host app. (Note: Requires AudioTools 6.6 or later). Set up your mic in the front of the theater, and do your testing in another room, or put AudioTools Wireless and the mic inside a loud car or club, or set it up outside, monitoring the sound outside of the building. Set up several units and switch between them from a single AudioTools app, to check the sound in different locations without having to physically be there.
