MPEG-4 CELP

Features

• Encoder compresses linear PCM input signals (16 bits 2's compliment form) sampled at 8 kHz and 16 KHz to bitstream of 3.85%9623.8Kbps, Decoder decompresses compressed bit streams into 16 bit PCM samples.
• Support for MPE (Narrow band %96 8 Khz, Wide Band %96 16 Khz) mode of MPEG4-CELP
• Support for RPE (Wideband %96 16KHz) mode of MPEG4-CELP
• Support for variable bit rate mode of MPEG4-CELP (Fine Rate Control)
• Optimized DSP Implementation
• C callable interface for encoder and decoder
• Re-entrant multi channel implementation
• Supports CELP-cbr and CELP-vbr modes as defined by the ISMA Specification 1.0
• Supports Error Resilient CELP bit streams
• Supports VAD/CNG/DTX
