QCP

From Wikipedia, the free encyclopedia

The QCP file format is used by many cellular telephone manufacturers for providing voice ring tones. It is based on RIFF, a generic format for storing chunks of data identified by tags. The QCP format does not specify how voice data in the file is encoded. Rather, it defines sets of meta-data which identify the encoding scheme used, where individual chunks of the encoded voice data are stored in the file, and supplementary information such as indexing points and text labels. Typical encoding schemes used in QCP files are QCELP and EVRC.
