DesignWare® ARC® Audio Adaptive Multi Rate Wide Band Plus (AMR-WB+) software for the DesignWare ARC Sound AS211SFX and AS221BD audio processors consists of a speech system for devices such as tablets, mobile phones and voice over IP (VoIP) applications. Compared to AMR-WB, AMR-WB+ provides a wider bandwidth and higher sampling rates in order to deliver a better audio experience.  DesignWare ARC Audio AMR-WB+ Decoder
- Compliant to the following 3GPP (GSM) standards
- 3GPP TS 26.274 (test vectors)
- 3GPP TS 26.290 (audio speech codec)
- Supports all bitrates of the AMR-WB+ standard:
- 5.2 to 36 kbps (mono)
- 6.2 to 48 kbps (stereo)
- Supports all nine AMR-WB speech codec modes
- Sampling frequency 16-48 kHz with a sample size of 16 bits
- Voice Activity Detection (VAD)
- Comfort Noise Generation (CNG)
- Discontinuous Transmission (DTX)
- Robust to memory latency: 62 MHz processor load at 100 cycles latency
