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.

  • Can you please refer such an interface?? Since I couldn't find one with 4 or more than 4 inputs – Mathematicians Dec 6 '18 at 13:11

  • You will probably need condensor microphones with a very low noise floor and definitely a solid device such as the RME, possibly running at higher sampling rates. You are likely to need fairly long cable runs so an interface that uses balanced inputs is likely to be necessary. – Mark Dec 6 '18 at 13:33
  • over what sort of distances are you trying to localise sound? – Mark Dec 6 '18 at 13:35
