Useful Software “HROFFT”

This software was developed by Mr. Kazuhiko Ohkawa as I wrote. If you want to use this software, please contact me (address). Almost of Japanese observers use this software, and many observers in the wolrd also use this software. The biggest merit is to work under Windows operating system. I recommend that using computer has over 133MHz CPU and over 32MB ROM. This software works under Windows95, 98, Me, 2000, XP. Of course, this software analyzes Line-In sound, the soundbord (or card) is needed.
