Samsung Galaxy S3 features a Wolfson audio chip, but not in North America


Published onJune 27, 2012

For the last few weeks, the Samsung Galaxy S3 has been in the news for all the wrong reasons, starting from the unexpected North American launch delays due to “unexpected demand” to an isolated case of the device catching fire.

This time, there’s finally some good news for Galaxy S3 owners. One of the speculations that made the rounds during the absolutely crazy pre-launch phase, was that the Samsung Galaxy S3 would feature a Wolfson audio chip. The rumor was confirmed by the reputable Scottish company themselves, in a press release issued yesterday.

The WM1811 audio chip is a 24-bit, two channel DAC (digital-to-analog converter) that includes active noise reduction circuits and a four-channel equalizer. According to Wolfson’s press release (see below), the WM1811 provides crystal-clear voice quality and enriched audio playback for music, along with minimum power consumption, to ensure a much longer battery life.

We all obviously prefer and appreciate high-quality audio in our devices, especially when we’re shelling out over $800 for it. That being said, I’m no audiophile, so in my completely amateurish comparison between the sound of the Samsung Galaxy S3 and the HTCOne X (with the much-hyped Beats Audio), I couldn’t really notice a difference with the headphones on. But there was a noticeable difference in volume and a slight difference in quality as well, when using the external speaker.

Unfortunately, it looks like North American consumers have pulled the short straw yet again, after losing out on quad-core processors due to LTE radio compatibility issues. According to Francois Simond (@supercurio), the US version of the Galaxy S3 uses a Qualcomm WCD9310 audio chip instead.

What are your thoughts? How glad are you that Samsung decided to use a Wolfson audio chip? How disappointed are you at the use of different DAC for the US variant? Does the 2GB RAM make up for this switch as well? Let us know in the comments section below.
