Currently, iPadOS 17 only permits audio from a single source. This can be the iPad’s own microphone or one connected via a USB cable or USB hub. If you need multiple audio sources in your setup, e.g. you’re a gamer who wants to capture game sound along with your own commentary, there are a couple of options to capture both for your streaming or recording.
The first is to use an audio mixer. Once you connect both of your audio sources to the mixer, you can then select it as a single audio source within Camo.
A second option that works is using a two-transmitter wireless microphone system like the DJI mic. In a gaming setup, we slid the receiver into the shoe mount of our camera, with a cable into the camera’s sound input. We then attached one transmitter to the gamer/subject, and connected the second to the microphone/audio port on our gaming console via the same type of male-to-male 3.5 audio plug that connected the receiver to the camera. Both transmitters sent their signal directly into the receiver, and by selecting the camera’s capture card as our audio source, we were able to capture good sound from both sources.
We anticipate that future updates of either the iPadOS or Camo Studio for iPad will permit multiple audio sources to be connected more readily.
The best way to connect multiple devices to your iPad is through a hub or dock. To keep the iPad from being overtaxed, it’s helpful to use ones that’s powered, and - if you’re connecting more than a couple of peripheral - that uses the faster Thunderbolt standard. This will also enable you to keep your iPad charged while you use it.
