welcome to the experts

Coding Technologies provides the best audio compression for mobile, digital broadcasting, and the Internet. Our technologies can be added to any perceptual audio codec to dramatically increase its bit rate efficiency multiple times.

We are tirelessly working to improve our existing technologies and audio codec systems, contributing to the most influential open standards bodies such as ISO/MPEG, 3GPP/2, DVB, or Digital Radio Mondiale. Our technologies are already in widespread use in consumers and professional audio products and systems. See our partners section for further reference.
