G10L 19/00 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)
Introduced: January 2000
Title
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
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)

Of 10 combined children, 7 exist in both systems.
3 codes are CPC-only extensions.
Note: 1 CPC extensions are marked as secondary classification only.
1 shared codes have differing titles between IPC and CPC.
