I used to think: Audio jitter in my Windows PC does not matter because the data are send by USB cable to an external DAC (digital to analog converter). But. I can hear it. I have done experiments with a software called ProLasso, putting Windows services on certain CPU kernels: I can hear differences. If low jitter: I hear thousands of more details and feel a much better rythm. This helps: - Disabling as many drivers as possible (dvd drive, network, graphics card). - Disabling DEP (data execution prevention). - Avoid as many services as possible. - Disable logging in Windows. - Disable BIOS functions that prevent totally absolutely top speed. (Cooling is a problem!) I could continue. However. An OS is what I need to remove? Then what about my HD TV, radio, gaming? What is the solution? That type of knowhow is a secret in the music industry?
