The available digital audio stream depends on your device and operating system. For a list of compatible devices please visit http://www.extreamsd.com/USBAudioRecorderPRO/

The MicroStreamer is simple to use and provides a level of improvement in sound quality that must be heard to be believed. To improve your computer's sound quality, the microStreamer takes over the job of processing the digital music stream from the computer, critical for producing great sound.
Do not be fooled by its modest cost or small size: its ability to transform the sound of your computer’s or other hosts’ music files or streaming audio into a state-of-the-art musical experience will make a believer out of even the most critical listener. As with other HRT products, the set up and operation of the microStreamer is super-easy: simply use the included USB cable and hook the input of the microStreamer into any available USB port on the host computer or other compliant host, and select it as the default output device.
Now you are ready to experience your music with the best sound possible. Operating essentially jitter-free via the use of its high performance asynchronous USB transceiver, the microStreamer, when plugged in, automatically performs an "electronic handshake" with the computer or other host and tells it that the microStreamer is to get all audio signals sent to it instead of the Digital-to-Analog converter (DAC) that is built into the computer, and that it, the microStreamer, is in charge of all data-transfer timing instructions.
Then, to enjoy music in your home entertainment system, just use a good quality set of interconnects that have a 1/8” (3.5 mm) stereo male plug on one end (for the microStreamer) and standard RCA plugs on the other end to connect the fixed-output side of the microStreamer to any available line-level analog input on your integrated amplifier, preamp, receiver, or powered loudspeakers with an analog attenuator. For headphone listening, simply insert the 1/8” stereo plug from the ‘phones into the variable-output port of the MicroStreamer; analog volume control of its OCL (output capacitor-less) headphone amplifier is accomplished by using the digital “slide” control on the host computer’s music playback software to adjust the internal analog volume control of the microStreamer. This clever arrangement allows the full audio quality of the microStreamer to remain intact, without the known sonic degradation potential of digital attenuators. The signal remains pure, clean, and full-range without the high-pass filtering that is inherent in any power amplifier that is capacitor-coupled at its output.
With its jitter-free asynchronous interface, combined with processing power that allows native-resolution (no up-sampling) playback of digital music data up to a maximum of 24-bit/96k material, the microStreamer will transform your computer, tablet, or Smartphone into a better-than-CD quality source. Utilizing native Audio Class 1.0 drivers (present in all modern PC, Mac & Linux computers) there are no extra drivers or software to install. LED indicators on the side of the microStreamer’s aluminum housing show the current sample rate (32k, 44k1, 48k, 88k2 & 96k), as well as the state of its built-in mute circuit; you will always know at a glance your systems operating mode.
As with other HRT products, as firmware improvements become available, HRT's UpStream utility allows the Music Streamer II to be updated right from the computer's desktop in a matter of seconds. The High Resolution Technologies microStreamer, along with all the other products in the HRT lineup, is designed and manufactured with pride in Southern California.
