Abstract

The most precise digital-domain method for the generation of arbitrary periodic audio signals was presented. Advantages of this method are: highest available precision with a given D/A converter, and low requirement on the speed of hardware and software, because synthesis of waveform is not performed in real-time. Hardware and software only have to be capable of doing real-time looping through sound file generated in the RAM buffer. Details of the waveform synthesis should be sufficient for easy implementation of this algorithm on different computer platforms
