DSP Sona-Graph, Model 5500

The DSP Sona-Graph is a dedicated (i.e., not computer-based), real-time, audio spectrum analysis instrument which was designed "from the ground up" for high speed signal analysis and display. In terms of raw processing power, the DSP Sona-Graph is unmatched in Kay's acoustic analysis product line. The instrument is the current iteration of many generations of Sona-Graph which Kay has manufactured since the early 1950s.

Though supplanted by computer-based systems (i.e., CSL) for some applications since its introduction in 1987, the DSP Sona-Graph continues to be widely acclaimed for its unique capabilities in real-time signal scanning, editing, analysis, and teaching in the diverse fields of bioacoustics, linguistics, speech pathology, forensics, singing analysis/training, and signal/intelligence.

The 5500 contains a computer interface which allows data to be exported to a computer and then analyzed with other programs such as the KayPENTAX Computerized Speech Lab (CSL). For information on related acoustic analysis products from KayPENTAX, see:
