Algorithmic and Wavetable Synthesis in the MPEG-4 Multimedia Standard
Eric D. Scheirer, Ray Lee · 1998
this paper, we focus from an applications standpoint on the uses of these two methods for the very-lowbitrate transmission of sound. We will contrast the use of wavetable and algorithmic synthesis in various applications, describing the advantages and disadvantages of each technique. We will also present a discussion of hybridized audio synthesis in MPEG-4, in which elements of both the wavetable and algorithmic toolset are used. We will relate the very-low-bitrate coding techniques possible with MPEG-4 Structured Audio to the low-bitrate coding of natural sound in MPEG-4, and discuss new prospects for hybrid low-bitrate coding which makes use of concepts both from traditional compression and Structured Audio coding. The paper concludes with a discussion on the current state of implementation of the standard.
