HD audio (24bit, 192KHz and upwards) is something that many audiophiles rave about. Having used IQ Audio's Pi-DAC+ in my home, I wanted to replicate the audio-goodness in my new car, especially as it had a USB power source and AUX input in the driver's armrest! Enter the Raspberry Pi Car Audio Player
In this project, I use the Raspberry Pi Zero, Pimoroni's pHAT DAC, UUGear's Zero4U USB hub and MoOde Audio to create a HD audio player that runs in my car.
Once you have soldered the headers to your Pi Zero and the pHAT DAC, it is quick to assemble by popping the pHAT DAC onto the Pi's GPIO pins, and then securing UUGear's Zero4U as per their instructions here (http://www.uugear.com/doc/Zero4U_UserManual.pdf).
MoOde Audio, AirPlay and WiFi Access Point
As I am going to be using my Pi in my car, I needed a way of controlling my Raspberry Pi car audio player so when I found out that mOode now creates a WiFi Access Point (AP) that you can connect to as a way of accessing the user interface – all from a fresh install – I was suitably impressed! This is such a cool feature and solved my next problem before it even started!
Controlling the audio
As the Pi creates its own WiFi Access Point, thanks to MoOde's excellent built-in feature, I simply connect to this using my iPhone (any smart phone works) and open up the UI by navigating to moode.local in my browser. I can then queue up songs (before I drive away of course!) and enjoy the high-end sound during my journey.
