Qualcomm claims that the audio codec integrated into its flagship mobile SoCs can rival DACs produced by dedicated manufacturers. Its latest iteration of these are found in the new Snapdragon 730 mid-range chipsets. They are called the WCD9370 and WCD9375 Aqstic codecs.

Qualcomm develops audio codecs called Aqstic for its mobile-device SoC. The company claims that the current highest-end of these, the WCD9341, "measures better objectively compared to some of the best branded audio DACs out in the industry today". Its latest successor, the WCD937x series, is intended for more mid-range processors. Nevertheless,Qualcomm claims to have recruited expert help in their production.

This has apparently come from Golden Ears: individuals whose ability to "identify and classify even the slightest distortions in music, the characteristics of different digital filters, reverb, colorization, panning, harmonics, and more" is recognized with an accreditation saying the same. Qualcomm has reportedly recruited some of them to help tune the new Aqstic line.

It consists of the WCD9370 and WCD9375 codecs, which are available in the Snapdragon 730 and 730G SoCs. Therefore, the work done on this software (which includes a Golden Ears filter that now also applies to the WCD9341) may enhance the sound experience found on recently-launched devices, as well as those becoming prominent in leaks concerning upcoming smartphones. They include the Redmi K20, Samsung Galaxy A70 and Motorola Razr 2019.

I became a professional writer and editor shortly after graduation. My degrees are in biomedical sciences; however, they led to some experience in the biotech area, which convinced me of its potential to revolutionize our health, environment and lives in general. This developed into an all-consuming interest in more aspects of tech over time: I can never write enough on the latest electronics, gadgets and innovations. My other interests include imaging, astronomy, and streaming all the things. Oh, and coffee.
