Hi, First of all I apologize for the irrelevance. This has little to do with Macs, although Linux is a Unix-like system I suppose. I film movies for a lot of personal projects, and I was hit with a big equipment failure. The XLR in 1 of my primary mobile recorder, the Zoom H4, doesn't work anymore. I tried all the contacts, the circuitry, etc. and couldn't find the short. (if anyone has an idea as to how to fix this feel free) Then I had an idea. Since the Raspberry Pi is so small and has USB ports, why not use it as a mobile recorder with my USB audio interfaces? I thought about the idea, and for it to work I'd need the following: 1. A real-time clock with the Raspberry Pi for proper time codes 2. A battery and a big SD card for prolonged mobile use 3. Maybe a keyboard or remote of some sort to initiate recording 4. A suitable program that can do multi-track, multi-interface recording at 24/96, and automatically save it as a separate file whenever the recording stops 5. A case to store the Pi (I'd be carrying the entire setup in something like a backpack) This would effectively give me an expandable, mobile-enough recorder with high quality audio and timestamps for under $120. Audio monitoring would be enabled by routing all audio out to one of the audio interfaces. Since I have 2 2-input interfaces, I'd be getting a Linux-powered 4-track recorder. Of course not many people have tried such a thing, and I was wondering how feasible this even sounds. Is it even doable? To give an example of what one would look like with this setup, here's a visual simulation.
