  • can now be fully enjoyed with aptX™ HD.
  • Typically used in professional broadcasting, the original aptX™ audio codec is widely used
  • for 16-bit near-CD quality sound.
  • The benefits of the aptX™ codec include superior compression, low computational cost,
  • and low transmission delay.
  • Launched in early 2016, the next-generation aptX™ HD codec is capable of transmitting up to
