The Engadget Interview: Mike Hickey, CEO of Wolfson Microelectronics
Look at the prevalence of Wolfson's audio chips today, in everything from audiophile DACs to smartphones like the Exynos-powered Galaxy S III and Galaxy S 4, and it's hard not to be impressed. Factor in the company's humble beginnings in 1984 as a university offshoot in Edinburgh, Scotland, and the growth story becomes even more dramatic. The company shipped its billionth chip in 2008, its 2 billionth in 2012 and now expects to sell a billion per year by 2015. It's ironic, then, that at the start of its journey into mobile devices Wolfson actually failed to grow quickly enough, resulting in the loss of its biggest and most high-profile customer. With Apple using its chips in a number of iPods, the Scottish company just couldn't scale up to meet a sudden rush of demand. It missed some deadlines and Cuptertino left it out of the iPod Classic as it shifted its loyalty to Cirrus Logic, where it has stayed ever since. How did it recover? Where is it headed next? And how will it break Qualcomm's continuing grip on smartphone audio in the US? Read on for answers from CEO Mike Hickey.
Wolfson WM5110 audio chip outputs 'studio master' sound, may appear in next Galaxy S (ears-on)
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.
