What is a .QCP file?
QCP holds Qualcomm PureVoice audio, recorded by older CDMA phones.
- Did you know
- QCP was the voice-recording format of many early Qualcomm-based phones.
- QCP is a container based on Microsoft’s RIFF structure and typically wraps speech encoded with Qualcomm’s QCELP or EVRC codecs.
- The format was designed to squeeze human voice down for CDMA cellular networks, with QCELP running at either 8 or 13 kilobits per second.
- What Analyser reads
- Identify many more audio formats: lossless/hi-res codecs (Monkey’s Audio, WavPack, TAK, True Audio, DSD/SACD, Musepack), pro containers (Core Audio, RF64/BW64, Wave64, Sun AU, Broadcast Wave with timecode), speech/mobile (Speex, AMR-WB, QCP, 3GA, M4R, GSM), MPEG Layer I/II, instrument banks (SoundFont, SFZ, DLS, RIFF MIDI, GigaStudio), ringtones (RTTTL, iMelody, SAP), tracker modules (MOD, XM, IT, S3M, OctaMED, 669, Oktalyzer), chiptunes (NES NSF, SNES SPC, VGM, Game Boy GBS, AY, YM) and Audacity projects.
- Depth of analysis
- .QCP is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .QCP file
- Drag a .QCP file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
