What you're looking at above is a demo board carrying a next-gen Wolfson WM5110 audio chip for smartphones. This bit of silicon isn't in any market-ready handsets just yet, hence the DIY setup, but given Wolfson's well-cemented partnership with Samsung there's every chance this'll be the audio hub in the next Galaxy S, as well as potentially in other manufacturers' phones coming out in 2014.

One of the WM5110's headline features is the ability to handle high sample rate music tracks at 24-bit and 192KHz, aka "studio master" or "better than CD quality" sound. Such skills are generally reserved for pricey standalone DACs like iRiver's AK100, which allows Wolfson to claim that this is the first implementation for inside a smartphone. We have an ears-on video for you after the break, but it's not much use for judging audio quality -- the event was too noisy even for us to attempt that, so we'll just wait to do another audio round-up in more controlled conditions -- but at least there's some proof of principle. On the other hand, if you're unconvinced as to whether 192KHz is even a worthwhile spec to have in smartphones, then read on to learn about some of the WM5110's other abilities, which have a more practical bent.
