Then it was time to have a go at sending audio to it via Qlab. So now I had a working system, and all that was left to do was to find a way to attach all of this inside the radio (lots of glue and Velcro were involved here – not my finest prop making), and then plug in the IEM (for this project I used a Shure PSM300 personal monitoring system). The amp inside the radio, hooked up to the internal loudspeaker – IEM not pictured. Working The Processīack to the radio, I powered through and soldered the entire circuit board and tested it by plugging my phone into the mini-amp via a mini jack cable and hooking up two other loudspeakers (L/R) that also came free with the kit from the online shop. There are various other little tricks that can be set up, too, including the sound cutting out as a character lifts the phone to her ear, or no sound at all and just a text vibrate. Qlab is just sending OSC (Open Sound Control protocol) commands – all of the audio “lives” in the app.įrom there, the sounds can be triggered via OSC from the assigned Qlab file (with relevant IP addresses), and in the most recent version, the app allows setting up “heartbeat” pings so that it doesn’t become completely inactive and triggers precisely when it needs to.

To get the sounds onto the StageCaller app you’ll need to download them from Dropbox and upload them in the app.
The sounds need to be downloaded from Dropbox and uploaded to the app. Practical radios are almost two a penny in theatre, among other fan favorites such as doorbells, telephones, intercoms, etc., all of which would have their own tried-and-tested ways of being produced.įor instance we’ve had a couple of shows that require practical mobile phones, and for this we use an app called StageCaller that works over MIDI/OSC – an iPhone is needed to do this, as well as Dropbox, and for the best results, a stable Wi-Fi connection that’s used solely for the phone.
