This FREEWARE package allows the user to view the time-wave and frequency spectrum LIVE from any Macintosh® sound input device. Real-time display is possible on faster Macintoshes; display rates of >110 frames per second are possible on a Power Mac 8100/100; 30 fps on a Quadra 950. A "Waterfall", or raster plot of previous spectral history, is presented in a separate window. Recording and playback of monophonic 8-bit sound is supported; a spectragram can be made of the captured data; whether recorded by SoundView, or imported from any sound file. A readout provides the frequency value of a point specified by the mouse cursor.
This package contains:
• This file: "SoundView ReadMe".
