Hi, I have an audio mixing desk that has a USB audio input / output (via the usual USB "B" connector).
I was wondering whether the Pi would make a good device to use as a sound recorder. The idea being, to leave the Pi connected to the desk during a gig, writing to the SD card. At the end of the gig - just pull the USB card out, read it in a PC to get the files out (or else transfer the files via ftp I suppose).
I thought about also adding a simple LED display via the I/O ports just to give confidence that the recording is working OK.
Just wanted to ask the experienced people on this forum for a few tips as I begin the project:
- If I need specific USB drivers, where to go for those?
- Do I need to upgrade my Pi? (it's got the first version of Raspbian on it)
- Do you expect a problem with latency or dropped samples at 44.1kHz stereo via USB?
- For simple I/O to drive LEDs on/off, can we use the pins on the Pi directly, or is a Gertboard (or something similar) a good idea?
If anyone else is interested in the project, let me know and I'll blog it as I go along.
