The Samsung Galaxy S III (a.k.a.GS3) was arguably last year’s second best-selling mobile phone, behind the iPhone 5, and the popularity of this non-Apple device—reportedly over 30 million units in consumers’ hands—in a sea of Android competitors speaks volumes. Smartphones do a lot, often serving as many folks’ primary media player, but they face the quandaries of all modern portable gear: Performance must contend with the realities of physical size and weight, as well as battery life. One such casualty is the diminutive digital-to-analog converter inside the phone, which turns the digital audio signals into analog audio that we can hear over headphones or the built-in speaker. As a GS3 user for the past 11 months, I have no major gripes about the onboard DAC (in this case built into the Qualcomm WCD9310 chip), but it is fair to say that it wasn’t selected only for audio quality, but perhaps partly because it’s tiny and it won’t overwhelm the phone’s battery.
