Hello all. I'm new to the Raspberry Pi (just got my first Pi, an RPi 3 Model B). I am looking to create an high-quality audio+video recorder out of my Raspberry Pi. (In a way, I'm basically trying to make a camcorder.) I want to add the Raspberry Pi Camera Module and the Cirrus Logic Audio Card to my Raspberry Pi. I require very-high quality recording.
I want to feed my line-level audio source (coming from my mixer via a 1/4" -> 3.5mm adapter) to the Cirrus Logic Audio Card line-level (pink) input. I'd like to also like to have a Raspberry Pi camera module connected and recording at the same time. I'd like to simultaneously record 1080p 30fps video from the camera module and 24-bit 96kHz audio from with the Cirrus Logic Audio Card. In other words, I'm looking to record very-high quality audio and video at the same time. I'd like both recordings to be in sync (in terms of the exact moment they start) and exactly the same length (in terms of the exact moment they stop). The audio and video do *not* have to be contained in a single file.
I've read about people recording high quality video or high quality audio, but haven't seen anyone doing it at the same time. My primary concern is whethter or not the Raspberry Pi will be able to process this much information in real-time, and have the ability to write all this information to my SD card fast enough (I happen to be using a Samsung Evo 64 GB Class 10 Mirco SD card). I know from hacking my DSLR camera for video using Magic Lantern software, the place where things fall apart on those systems is having enough speed writing to the card.
Has anyone tried to turn the Raspberry Pi into such a high-quality recorder? Were you able to record very high quality without any problems?
My goal is to eliminate (most) post-production work. If I could record audio and video directly to a Raspberry Pi, that would just about get me there for my needs. I know I can record to an external recorder (like a Tascam DR-05 audio recorder or an external HDMI video recorder, both of which I already own), but this would be so much easier.
