About QCELP files

The .QCELP file contains audio data compressed using the Qualcomm Code Excited Linear Prediction algorithm. These files are typically wrapped in a RIFF structure and were designed by Qualcomm to compress human speech for early CDMA cellular networks. The legacy Qualcomm PureVoice software was originally used to handle these recordings. Today, the .QCELP format is completely outdated and proprietary. Modern operating systems, web browsers, and default media players cannot read or play these files natively. Users attempting to open a .QCELP file will encounter errors unless they install legacy software or specific, hard-to-find codec packs. To actually listen to the audio, you must convert the file to a ubiquitous standard like WAV or MP3. Because the codec aggressively discards non-speech frequencies, you should expect low-fidelity voice audio; conversion will not restore lost quality. Standard online converters often fail with this format because they lack the proprietary decoding libraries required to unpack the audio stream.

Convert.Guru analyzes your QCELP file, detects the exact format, and lets you read the text inside.
