So I’m wrangling Windows 10 get the best sound. Everyone’s saying “go bit-perfect,” which means using WASAPI exclusive or ASIO (actually, just ASIO for purists). The catch is, you can’t use a system wide equalizer (like equalizer APO) with either of those drivers. I use Equalizer APO because it’s a free parametric equalizer that recognizes the autoeq presets. You can, however, use WASAPI shared and use the equalizer. But, people say that driver is no better than the original mixer/directsound. But, that last point depends what how your audio sources are set up.
So, I set up Foobar with the SRC resampler component and set it to best sinc, with a 4x upsampling. I initially didn’t hear a difference, until I changed the Windows sampling rate from 44.1/24 to 176.4/24 (4x 44.1). That will make it on par with most of my music (44.1) and any of the higher res music will simply be downsampling to 176.4. I’m assuming Windows can’t fuck up downsampling audio (too much). If I’m wrong, let me know. It’s a learning experience.
So, when I changed it to 176.4, I heard a noticeable improvement. I guess that’s what they mean by less of an antialiasing filter.
