What is QCP?
Qualcomm PureVoice QCELP recoder and player voice file. Qualcomm's PureVoice® products offer a range of superior voice and audio enhancement software for CDMA products. Optimized for Qualcomm's Mobile Station Modem (MSM™) device platforms, the PureVoice product suite consists of voice recording technology, voice recognition software and audio automatic gain control.

PureVoice Voice Recording technology provides landline-quality voice transmission that operates at variable encoding rates in order to take advantage of natural pauses in human speech. The high-quality, high-compression solution is useful for store-and-forward as well as streaming applications, and the technology accommodates erasures (dropped data), resulting in better performance on real-time applications.

PureVoice Audio Automatic Gain Control (AGC) provides the highest quality stereo enhancement software available for Qualcomm's MSM platforms, enabling CDMA handset manufacturers a simple "drop-in" solution for enhancing the sound quality and usability of their phones. PureVoice AGC is most effective in adverse noise conditions where background noise would otherwise prevent intelligible phone conversations.

What is AWB?
Adaptive Multi-Rate Wideband (AMR-WB) is a patented speech coding standard developed based on Adaptive Multi-Rate encoding, using similar methodology as Algebraic Code Excited Linear Prediction (ACELP). AMR-WB provides excellent speech quality due to a wider speech bandwidth of 50-7000 Hz compared to narrowband speech coders which in general are optimized for POTS wireline quality of 300-3400 Hz.

AMR-WB is codified as G.722.2, an ITU-T standard speech codec, formally known as Wideband coding of speech at around 16 kbit/s using Adaptive Multi-Rate Wideband (AMR-WB). G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB. The corresponding 3GPP specifications are TS 26.190 for the speech codec and TS 26.194 for the Voice Activity Detector.

A common file extension for AMR-WB file format is .awb. There also exists another storage format for AMR-WB that is suitable for applications with more advanced demands on the storage format, like random access or synchronization with video. This format is the 3GPP-specified 3GP container format based on ISO base media file format. 3GP also allows use of AMR-WB bit streams for stereo sound.

The AMR-WB bitrates are 6.60, 8.85, 12.65, 14.25, 15.85, 18.25, 19.85, 23.05 and 23.85 kbps. Compared to narrowband speech codecs (like AMR) optimized for traditional telephone voice quality of 300-3400 Hz, the AMR-WB codec's wider bandwidth of 50-7000 Hz provides excellent speech quality.
