9.8 SUMMARY
In this Chapter, we reviewed sinusoidal signal models for low-rate audio coding. Some of the key topics we studied include the ASAC, the HILN algorithm, hybrid sinusoidal coders, and the STN model. The parametric representation of sinusoidal coders has the potential for scalable audio compression and delivery of high-quality audio over the Internet. We will discuss the scalable and parametric audio coding tools integrated in the ISO/IEC MPEG 4 audio standard in the next chapter.
