Thanks a lot for your help and i wait for your answer. have a nice day. Edgardo. 
There ways to minimize latancy, but multitasking computers require recording/playback buffering which means there are always recording and playback delays. If you make the buffer (latency) too small, at some point youâll start to get âglitchesâ. ASIO drivers can also help, but by default Audacity does not work with ASIO. (I doesnât look like there are any ârealâ ASIO drivers for your mic either, but you could probably use ASIO4ALL.)
But, your microphone has a headphone jack for direct zero-latency monitoring. Youâll have to figure-out how to monitor yourself and the background music through the micâs headphone jack, and I think there is some information in the micâs user manual to help with that.
Itâs always if you can bypass the computer for âlive monitoringâ. Higher-end audio interfaces often have zero-latency âhardware monitoringâ and in a pro studio you are likely to find an analog mixer as part of the monitoring setup.
They donât all do monitoring like that, but we certified three hardware devices that can do Perfect Overdubbing. All of them require plugging your headphones into the device and not the computer. Live sound from the computer will always be late.
