Adaptive Multi-Rate Wideband

Adaptive Multi-Rate Wideband (AMR-WB) is a technology used in mobile phones to improve voice quality during calls. It dynamically adjusts the audio compression rate based on network conditions, ensuring clear sound even when bandwidth varies. By capturing a wider spectrum of sounds, AMR-WB produces more natural, richer audio compared to older systems. This adaptability helps maintain call clarity and stability, making conversations more pleasant and less prone to distortion or dropout, especially in challenging network environments.
