  • Fundamentals of USB Audio
  • Microsoft is (finally) adding support for USB Audio 2.0 in Windows 10. "As you have found out, we have an initial version of a USB Audio 2 driver in the latest Windows Insider release!" http://answers.microsoft.com/en-us/insider/forum/insider_wintp-insider_devices/windows-support-for-usb-audio-20/0d633b9f-3193-4c63-8654-fb10b3614a04?page=19

  • Dual-voltage regulator meets USB-power needs
  • I don't think this circuit works if you are drawing any current from VBUS. If the load on the "5V" terminal is 50 ohm, for instance (drawing the standard unit load of 100 mA at startup), then the "5V" output never rises above the divided voltage of 2.5 V, so the 2N3906 never turns off, and the Si2335 never turns on.

  • Neil Young: Say Yes to 24-bit/192-kHz audio
  • The Frey effect is not "hearing microwave frequencies". It's literally hearing microwaves. As in radio waves, not acoustic waves. The microwaves are heating the insides of your ears, which produces a demodulated clicking sound at audible frequencies. You aren't hearing microwave frequencies. Humans can not hear any frequencies above 20 kHz, and trying to play them back on speakers *degrades* the sound through intermodulation distortion. Yes, you can hear a difference, because the 192 kHz version is WORSE.

  • Fundamentals of USB Audio
  • "O/S vendors can supply a single USB Audio driver that drives a multitude of devices" Except that Windows still doesn't support USB Audio Class 2.0. Are they waiting for someone else to do it? If someone else did it, it would work with any class-compliant device, right?
