I would like to know if there are options for custom kernels and music players optimized for bluetooth audio (and its codecs)? So far I see that the bluetooth device will have an audio class driver that will bind to codec in Windows (or the driver will come with its own codec), and I could pass...

I would like to know if there are useful guides available on PCB design for DACs (probably something oriented towards medical grade devices)? I have had formal education in certain branches of electronics if that helps and have also taken considerable time to learn designs online (few nice...

I realized that playback software's like foobar actually limit fidelity (even when using asio or wasapi). I switched to winyl a couple of months. Someone had measured it a while back couldn't find it now. Winyl is measurably superior to foobar. Don't get me started on stock players they are...

I'm pulling in a few technical posts, but nothing relating to measurements but rather relating to guessing what I'm hearing :: please let me know if it violates any rules. I received my supra cable 2 days ago and have been comparing with the stock cable on the apogee groove. I believe I'm...

My current setup looks like this Surface book -> Apogee groove -> burson fun -> shure srh1540. The apogee groove outputs 5v at 100%. It has its own driver for windows and it's master volume scale is there in db. I pulled it down by 8db in the apogee groove control panel. 8db down brings it to...
