Introduced: January 2013

Full Title

Full titles differ between systems:

IPC:

Speech or audio signal analysis-synthesis techniques for redundancy reduction, e.g. in vocoders; Coding or decoding of speech or audio signals, using source filter models or psychoacoustic analysis > using predictive techniques > Vocoder architecture

CPC:

Speech or audio signals analysis-synthesis techniques for redundancy reduction, e.g. in vocoders; Coding or decoding of speech or audio signals, using source filter models or psychoacoustic analysis (in musical instruments G10H) > using predictive techniques > Vocoder architecture

CPC subdivides this area 3x more granularly than IPC with 2 additional codes.

2 codes are CPC-only extensions.

IPC defines codes here since 2013.
