Dirac claims its software can improve the sound of any headphones
The best headphones aren't perfect.
In fact, I doubt that any company will ever make a set that are entirely without flaws. That's not because one of them does anything wrong per se, but mostly due to the fact that everyone's taste is different. Eve...
USB-C and Lightning headphones aren’t great news for everyone
The 3.5mm port is dying -- at least when it comes to smartphones. If the persistent Lightning headphone rumor wasn't enough to persuade you, the fact that Motorola beat Apple to the punch should be. Motorola's new Moto Z and Moto Z Force don't have t...
Is Qualcomm considering an AR benchmark as ‘the mother of all tests’?
Today at the Qualcomm mobile benchmarking workshop in San Francisco, Jon Peddie of Jon Peddie Research suggested that using augmented reality (AR) to test the performance of mobile devices could be "the mother of all tests." By stressing all processors and sensors on modern smartphones and tablets -- including CPU, GPU, DSP, ISP (image processor), GPS, gyro, compass, accelerometer, barometer, mic and camera -- the benchmark would represent the worst case scenario in term of computing load. While AR adoption is still in its infancy amongst consumers -- technology such as Project Glass still faces serious challenges -- Qualcomm's been very active in the field over the years and even provides and SDK for developers. Could this be a hint of what's coming from the company in terms of benchmarking beyond Neocore and Vellamo? Let us know what you think in the comments.

Dutch company NXP -- best known for it's NFC solutions -- introduced a new audio chip today that's set to significantly improve the sound quality of the micro-speakers commonly built into mobile devices such as smartphones and tablets. The TFA9887 integrated circuit combines NXP's CoolFlux audio DSP, a class-D amplifier with current sensing and a DC-to-DC converter to boost the output level of micro-speakers up to five times (up to 2.6W RMS) without damaging the driver. Class-D amplifiers are highly efficient and, when combined with a DC-to-DC converter, provide a strong and clear signal regardless of battery level. With current sensing, the chip uses feedback from the driver to optimize power delivery, allowing micro speakers to provide louder, richer sound with deeper, tighter bass over the entire lifetime of a mobile device. Are you ready to turn it up to 11? Check out the full PR after the break.
Update: Hit the break for NXP's PR video.
