What is a QCP file?
A .QCP file is an audio file encoded with the PureVoice format. Qualcomm created the QCELP (Qualcomm Code Excited Linear Prediction) codec for these files to compress human speech. Mobile phone networks and early digital voice recorders commonly used this format to save storage space. Internally, most .QCP files use a standard RIFF container structure.
How to open QCP files?
Because .QCP is an older audio format, default media players on Windows and macOS often cannot play it natively. You can install third-party software like VLC media player to listen to the audio. For mobile users, finding a compatible app can be difficult because modern operating systems lack built-in PureVoice support.
Best practices and troubleshooting
If your media player cannot open a .QCP file, the file might lack the correct file header or require a specific codec. Instead of installing outdated software, you can convert the audio. We recommend using convert.guru to convert .QCP files into standard formats like .MP3 or .WAV for universal playback.
