  • Stereo enhancement
  • Echo cancellation and noise reduction
  • Voice recognition
  • Audio codecs

For our customers, the program reduces time-to-market with many plug-and-play features already integrated on CSR’s platforms, reduces costs by replacing dedicated hardware with software alternatives and improves product quality through collaboration with world-leading audio experts.
