I'm using 4 microphones to built a microphone array. To interface them with my PC (running Windows), I bought four USB sound cards and using a USB hub I connect them to my system. Is there any synchronization problem associated with this setup?? if any, How can I tackle it?
These are not particularly solid interfaces. I would recommend a multi-channel interface rather than four individual interfaces. You would be much more likely to get solid synchronization between all microphones than you would with separate interfaces of this variety.
