Sorry to hear that you’ve been having some latency/dropout problems. These sort of issues can be caused by a large variety of factors, particularly on Windows systems since these inherently involve a lot of components made by different manufacturers, all of which need to communicate effectively with each other in order for audio to stream successfully. This being the case, often all that’s needed are a few updates and a bit of system optimisation and this can drastically improve the performance of a computer.
Are you using a Windows or Mac computer? Which specific operating system are you using?
Have you tried increasing the buffer size? This increases the recording latency, though it will also take some strain off your computer’s CPU (your CPU overloading is one potential reason that you might see the error you are seeing).
