AMRWB Meaning and
Definition
-
AMRWB stands for Adaptive Multi-Rate Wideband, which is a digital audio codec. It is primarily used for speech compression and decompression in telecommunications systems like mobile networks and Voice over Internet Protocol (VoIP) applications.
AMRWB is an advanced version of the AMR (Adaptive Multi-Rate) codec and is designed to provide superior audio quality, especially in wider frequency ranges, compared to its predecessor. It supports a wider bandwidth of 50-7000 Hz, whereas the AMR codec has a narrower bandwidth of 200-3400 Hz.
The main purpose of AMRWB is to efficiently compress audio data in order to transmit it over limited bandwidth networks while maintaining a reasonable level of audio quality. By using various encoding techniques, such as variable bit rates and adaptive techniques, AMRWB is able to optimize the trade-off between bandwidth usage and audio fidelity.
AMRWB also offers different encoding modes or bit rates, ranging from 6.6 Kbps to 23.85 Kbps, depending on the desired audio quality and available network resources. This allows the codec to adapt to varying network conditions and adjust the compression level accordingly.
In summary, AMRWB is a digital audio codec that is specifically designed for speech compression and decompression in telecommunications systems. It provides improved audio quality in wider frequency ranges compared to its predecessor, AMR, by using various encoding techniques and adaptive bit rates.
