Hi, I’m looking for a solution to a audio recording problem. It might be a lot simpler then I think, but I’m not finding a straightforward answer.
I’m looking to create a recording device that can take 2 audio inputs and record them to a USB drive in separate tracks. Without any set time limit. The limiting factor being the size of the USB drive.
I would assume (probably incorrectly) that most microcontrollers should be able to handle a task like this with the correct components and programing.
My overall goal is to create a working prototype that I can use as a proof of concept for a funding campaign.
Sorry if I’m being a little vague, I just don’t know what questions to ask at this point. I would like to get in touch with someone that has a better grasp on this kind of equipment than me.
By the time you design and construct such a device, you could have spent a $2 more and got one off the shelf. This would be a fun project if you wanted to learn audio… But if this is a one time project, your going to get discouraged.
from what I know… you’d need a USB Host shield just to talk with the USB/flash drive… (thats roughly $20+ right there!)
I think the Adafruit WaveShield has a library that records audio… but I think it saves to a SD card instead…(and even then I’m not sure how much you can record in one go!)
Two comments have mentioned off the shelf devices. Could you put up a link to one or two of them for me, so I can see what you are suggesting. I haven’t been able to find what I’m looking for for under $300.00
