if only there were some good flows for attaching sound input / outputs & input devices over wifi

there are some technical means. one could use usb-ip[1] to bridge peripherals, for example. but few rise to the status of "flows", good well paved paths.

Netcat and sox works spendidly:

    rec -p | nc -l 7777

    nc 192.168.1.11 7777 | play -v 0.1 -

That can work, but probably not very well. Without real-time resampling some buffer in the path will underrun or overrun depending on whether the recording soundcard is sampling slower or faster than the playback soundcard. The clocks are not synchronized.

I wörks!. I have microphone outside soundproof windows and it is very synchronized, within 200 milliseconds. Good enuff for movies methinks.

Correccion. It is actually 3 seconds via Wifi. Previous test was direct loopback in the same machine. Good for music and other non-synchronized activities anyways.

Correccíon #2: If you manage to start both the server and client at the same moment, it is indeed 200 ms.

Is usbip finally usable?

In my experience, no. I would really love for it to be a thing as it's perfect for sharing devices on your computer to containers or VMs (i.e. program and debug your ARM MCU with a complex embedded toolchain and programmer running in a simple docker container). But in my experience USB over IP is still kind of a "here's a bunch of kernel modules and not a lot of documentation; good luck on windows" stage.

Sad, that was my experience too a few years back.
