I want better than bit perfect: a high performance digital filter engine to correct my room modes below Schroeder or to equalize (i.e. Was the limiter at the input of Windows audio engine, the output, or both? Do all sources needed to have volume reduced or would Windows' global volume work? I decided to find out.Ī commonplace sledge hammer detente is to just give up and use ASIO or WASAPI exclusive and bypass Windows' audio engine all together, for bit perfect operation. But I've seen no study on what to do about it. Mathew Van Eerde showed that Windows has an embedded limiter (CAudioLimiter) that can cause distortion if the signal is near full scale.Archimago showed that the Windows 10 upsampler (as of 2015) had significant performance issues.This is fixed by adding some Windows' volume loss Benchmark popularized that upsampling causes intersample-overs and clipping distortion within DAC chips.Over time, pieces of the "Windows audio sucks" puzzle emerged, but never a complete picture: I'm including supporting objective test evidence in keeping with the spirit of ASR. Sorry for the long post but my motivation is to share how to get effectively perfect audio from Windows, to save folks money and headaches, and to help end the endless debates. I decided to investigate this as I kept hearing issues with Windows, even after following common practice to (controversially) supposedly make it clean. Sceptics counterargued that bits are bits and Windows audio degradations are a figment of an over-active audiophile imagination. A debate has been long raging in the audio community that Windows isn't fit for use in a high resolution audio system.
