Nokia Research Center: Clear Call Quality and the AMR-WB - Tampere

AMR-WB (Adaptive Multi-Rate Wideband) speech codec is a standard that was largely developed by Nokia Research Center. It is a speech codec, which means it captures your voice, compresses it and transmits it wirelessly over the network. Compared to earlier technologies, it can efficiently capture and transmit a much larger audio bandwidth, which makes your voice sound very natural on the other end. In order to demonstrate the benefit of this technology, we travelled around the world and recorded live calls in noisy places.
