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 AAC?
Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at many bit rates.

AAC has been standardized by ISO and IEC, as part of the MPEG-2 & MPEG-4 specifications. The MPEG-2 standard contains several audio coding methods, including the MP3 coding scheme. AAC is able to include 48 full-bandwidth (up to 96 kHz) audio channels in one stream plus 15 low frequency enhancement (LFE, limited to 120 Hz) channels and up to 15 data streams. AAC is able to achieve indistinguishable audio quality at data rates of 320 kbit/s (64kbit/s/channel) for five channels. The quality is close to CD also at 96 kbit/s (48kbit/s/channel) for stereo.

AAC's best known use is as the default audio format of Apple's iPhone, iPod, iTunes, and the format used for all iTunes Store audio (with extensions for proprietary digital rights management).

AAC is also the standard audio format for Sony's PlayStation 3 and is supported by Sony's Playstation Portable, latest generation of Sony Walkman, Sony Ericsson Walkman Phone, Nintendo's Wii (with the Photo Channel 1.1 update installed for Wii consoles purchased before late 2007) and the MPEG-4 video standard. HE-AAC is part of digital radio standards like DAB+ and Digital Radio Mondiale.
