This innovation is made possible using new audio formats optimized for conversational spatial audio experience.

While it significantly enhanced call quality, like all previous codecs, it only offered a monophonic listening experience.
A key issue is noise reduction, crucial for enhancing speech clarity in parameters like concerts or nature.
Wind interference also poses a challenge by introducing unwanted noise and causing fluctuations in audio levels.
However, recent advancements in machine learning and intelligent noise reduction have addressed these issues.
This ensures that the essential sounds are transmitted while minimizing unwanted background noise.
Immersive audio setups with multiplemicrophonesand loudspeakers also face a major obstacle acoustic echo.
This happens when microphones pick up sound from nearbyspeakers, causing unwanted feedback.
Traditional Acoustic Echo Cancellation (AEC) methods often do not work well in these complex environments.
This improves audio quality, especially for spatial audio in real-time voice applications.
Importantly, the IVAS codec maintains full backwards compatibility, ensuring seamless interoperability with existing voice services.
The IVAS codec integrates a built-in renderer that supports head-tracked binaural audio and multi-loudspeaker playback using the MASA format.
This technology enables true 3D immersive audio experiences for various types of voice calls.
This scalability empowers service providers to support more users while delivering rich audio experiences.
Looking to the future, it is expected that voice-based user behavior will continue to evolve.
