HDTRACKS sample rate

I'm using WMP.

I know little about WMP. But one guess is your output device is now set up for hi rez, maybe because it is set to 16/44 in shared mode and that is limiting you. I would start by calling up Control Panel, Sound and select your output device. Hit Advanced. Check the 2 exclusive mode boxes. Then, select 24/96 from the pulldown and test to see if you can play 24/96. You may also want to select your output device and hit Configure. Some devices have you set allowed output characteristics.

I know websites that music producers and DJs can use to score free samples and loops for their games. The secret is knowing where to look. So, I’ve made the process even easier by compiling a list of websites that offer free samples and loops that you can use in your next project. Many of these sites vary from major sound databases like Freesound.org to small blog sites dedicated to a particular niche.

The best thing about being a tech type of person, is that once you learn to toggle up the ADC to the max sample rate, you can re-release all the old stuff from tape again at higher bitrates than anyone else is using.
Better than bitcoin mining, if you ask me.
