| Overview: | D2's Low Complexity (LC) ADPCM voice coder algorithm module compresses either linear or codec voice data to 32 kbps at significantly lower complexity than ITU-T G.726 standard coders. The quality of the LC ADPCM meets the "toll quality" requirements of speech applications. Designed to the VP Open interface, the LC ADPCM voice coder module easily integrates with other VP Open modules, runs in real-time concurrently with other VP Open modules, and handles any number of voice ports assigned to the DSP. Like all of D2's algorithm modules, LC ADPCM voice coder consists of robust software that is rigorously tested. |
| Ideal Performance: | Integrated with other VP Open modules and tested for concurrent real-time processing on multiple voice ports. |
| Algorithm Verification: | * Code error tests for stationary and non-stationary errors * Mean Opinion Score (MOS) test according to ITU-T P.80 specification for Absolute Category Rating * VP Open interface validation |
| Availability: | Currently available for the TMS320C5x with a demonstration package for the TI EVM50 DSP board. Contact D2 for other products availability . |
| Operating System Used: | The host, voice data input and output, memory allocation, and module to module communication interfaces must conform to VP Open specs. |
| Tools Supported By: | TI, White Moutain, DSP Research, Go DSP, National Instruments |
