- Description
- QCP (PureVoice Audio File) is a file format used for storing audio data in a compressed format. It was originally developed by Qualcomm for use in their CDMA phones and is optimized for low-bandwidth transmission. It is used primarily for voice recordings, such as voicemails and other audio messages.
- Compressed audio file similar to an .MP3 file, but offers several performance improvements; examples include a higher coding efficiency for both stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz; maintains quality nearly indistinguishable from the original audio source.
