When a LISNR tone is broadcasted simultaneously with music (overlayed), our signals will still work as they are at a higher frequency, hence there will be no interference with LISNR communication.
For example, LISNR tone files created by the Tone Creator on the LISNR Portal OR by using the LISNR Tone Service API will output a tone mp3 or wav file. This file can be mixed with any additional desired audio output and played on your broadcasting speaker/device.
By default, the Radius SDK for Desktop (macOS, Windows, Linux) will mix audio streams. If music is playing from a music application out of the desktop speakers, broadcasting a tone with the Radius SDK for Desktop will result in the Radius tones being played simultaneously.
By default, the Radius SDK for Android and iOS does not allow audio streams to be shared. If music is playing from a music application such as Spotify or Youtube, broadcasting a tone with the Radius SDK for Android/iOS will result in the music stream pausing and allowing the Radius broadcast to complete.
