QCP - Qualcomm PureVoice Audio File

What is a QCP file

The QCP file extension is a PureVoice Audio File. Qualcomm created the audio file and it has primarily been used for different types of recordings. QCP files are used to record both human voices and has also been extensively used for managing ringtones for mobile phones. It was designed to be able to handle most voice frequencies, as well as the normal types of pauses that happen during normal speech patterns. QCP files are frequently distributed via a simple email attachment. The attachment can be heard by using Qualcomm’s PureVoice Player-Recorder, which is a standard plugin that is a part of most email applications.

A QCP file can always be heard via the PureVoice Player and you can also embed the PureVoice SDK, provided by Qualcomm, into your device if you would like that functionality added. You can also convert QCP files into a PCM file to make them available on more devices. QCP is a container format, which means the file itself does not determine how the voice and audio files are encoded in the file. Files with the QCP extension usually use EVRC or QCELP encoding. It is also based on RIFF, which is a frequently used generic format for these types of files that stores chunks of data. This data is identified within the file by various tags.
