About Us


Qudelix is an audio system engineering company.

We deliver portable and affordable high-end audio solution for everyone. Based on the highly extensive background and experience of our R & D team, we design and implement the cost-effective high-end audio system. In a digital audio system, System-on-Chip (SoC) is one of the most important keys to the best product. We always keep up with the latest semiconductor technology and build the best application with optimized software and hardware.


Sony’s LDAC™ Official Technical Partner

As an Official Technical Partner of Sony's LDAC, we developed the LDAC solution for Qualcomm QCC512x platform, which is the best-in-class SoC for high-end Bluetooth application.

LDAC is a Bluetooth Audio Codec, which provides the best sound quality over the other codecs. Every Android device with Oreo or higher supports LDAC by default. Currently, over 38% of the total Android devices support LDAC, and the numbers are getting increased 

On the other hand, LDAC sink or receiver application does need Bluetooth SoC. QCC512x, the latest technology of Qualcomm, is the most advanced Bluetooth SoC, which is the best fit to LDAC receiver. QCC512x's ultra-low power consumption and the most powerful DSP capability enable the application devices to maintain high bitrate LDAC streaming more secure and for longer time.

We developed the LDAC solution for QCC512x SoC and support worldwide set makers integrate LDAC on their QCC512x applications.
