Is there a way to get real-time audio out from iPad to PC if iPad is doing usb audio?

Here’s my scenario…

iPad connected to digitone2 for audio and midi using AUM.
I can record audio from digitone using AUM.
No problem.

However, I’d like to be able to have the digital audio get from my iPad to my windows PC so I can use it as an audio source for streaming.

As iOS and windows can only have one audio interface live at the same time, I’m stumped on how this would be possible without sacrificing quality and going analog out of digitone (ie acting as audio interface for iPad) into another audio interface on the windows side.

This is going to result in a lot of latency and quality degradation.

Is there some solution, or hardware box that can address this?

    on Windows you can use ASIO4ALL to connect more than one audio interface. That's how I use both my audio interface and the TR6S via USB for a total of 14 channels

    Ok, but that still doesn't solve how to get audio from ipad world into the PC world...

    There ain't no way to do that without going through an audio interface on the Windows PC, unless you can put up with the latency of something like SonoBus over WiFi. If you can go over ethernet, the latency isn't too bad but it's bad enough to make it not usable for most live work.

    If you're streaming though, maybe the latency isn't as big an issue as it might seem. Unless you're doing your monitoring through the PC, maybe it doesn't matter if the audience gets the audio a bit after you. Just thinking out loud here, not knowing anything about what you're trying to accomplish.

  • If your iPad interface includes an ADAT port, I believe you can use it to create a direct digital audio connection between the iPad and a computer. There have been several threads on this over the years, including:

    Sonobus might be of interest to you. It allows for audio connections between devices via the network (works both in the LAN and over the internet). You get it for almost every platform. And for iOS there is an AUv3 version as well. Wireless networking is not recommended. With wired ethernet I get about 17ms latency between my two iPads that are connected to the same switch.

    I'll have to dig into that. Sounds promising
    Thanks

    One important thing to know: Always set the jitter buffers manually. There is an "auto" option, but in my experience this often results in crackling or it starts to increase the buffer size (latency) too much. Specially in the LAN, where you have a very consistent data stream compared to the internet there is no need for auto adjustment.

    One thing I was just thinking... The whole reason for doing this is so in an use my ipad as a midi processor. That's mainly what it's doing as I'm playing drums and any latency over a buffer of 64 is painful. My old air3 can do this fine.

    But since the endpoint is the digitone2 (I've the USB cable from ipad is connected to dn²) for audio and midi, I figured I needed to get the audio out from ipad to PC. And the pc would be the streaming box.

    And since the network is already gonna be hammer bandwidth-wise, your idea may not work.

    However, maybe I can use Bluetooth midi between drums and ipad for the midi work and USB the audio to the PC. BT midi surprisingly does not seem to impact latency as much as you'd guess. At least it doesn't feel like it when playing.

    Or I just ditch the ipad and rebuild the midi processes in the PC... But I really don't wanna do that.

  • As you mentioned above I think Bluetooth will work, but there will be some minor latency.
