There are many reasons why this can occur. Here are a few to mention:
1. Try using a different audio interface if possible and see if the problem can be isolated to a hardware device. If so, try plugging the device into a different power source. If you can isolate the issue to an audio device, visit the manufacturer's web site and download the latest driver.
2. Try increasing the ASIO Buffer Size/Device Block Size for your audio interface. If you are on a Windows machine, do this prior to opening Studio One.
3. Make sure that you are not using a 5400 rpm hard drive. You will want to use a 7200 rpm hard drive or faster. SSD drives are recommended if possible.
4. Some VST plug-ins create white noise when they are not activated. Make sure that you have activated all of your plug-ins.
5. Try using a different Mic and see if you can isolate the issue to a particular mic that might need to be serviced or replaced. You might want to also check your cables.
