(CELP, CodeExcitedLinearPredictive) coding technology and code rate above 16kbit/s. For example, 2~4kbit/s speech coding of 8kHz sampling frequency and 4~16kbit/s speech coding of 8kHz or 16kHz sampling frequency generally adopt parametric coding and 6~24kbit/s speech coding generally adopts code excitation linear prediction. The MPEG-4 study compares various existing audio coding algorithms and supports natural sound coding from 2 to 64 kbit/s. The MPEG-4 audio portion combines the synthesized encoding of audio with the encoding of natural sound and supports object features of audio. Compared to MPEG-1 and MPEG-2, MPEG-4 supports not only natural sounds (such as voice and music) but also synthetic sounds (such as MIDI). MPEG-4 includes the vast majority of MPEG-1 and MPEG-2 features and the strengths of other formats, and adds and extends support for Virtual Reality Modeling Language (VRML), object-oriented composite files (including Sound effects, video and VRML objects), as well as digital rights management (DRM) and other interactive features.
