WildSpectra and WildSpectraLive

for Mac OSX

Keith Wiley and R. Haven Wiley
c 2000-2010

The WildSpectra programs record, display, and analyze spectrograms (also called sonagrams)
on any Mac computer.

WildSpectra opens a sound file (AIFF, WAV, or SD2 formats, 22.05 or 44.1 KHz digitizing rates,
monaural), including files from digital recorders, and displays spectrograms of the file.

It can open very big files and spread the spectrograms all over your screen (even a 30-inch screen).
You can also edit the file, save PICT files of spectrograms, display frequency and time sections,
log time-frequency points from the spectrograms by clicking your mouse, and if you are lucky
even collect data automatically.

WildSpectraLive records sounds on your Mac and displays spectrograms in real time.

You simply connect a microphone or a tape-recorder to a PowerMac, iMac, or PowerBook
(through the sound input port or through a USB interface),
use the Sound Preferences Panel to select the appropriate input, and then launch WildSpectra.
You can make the real-time spectrograms big and spread them all over your screen.

All of these options -- and others -- become clear after examining the "Help!" items in the menus.
The menus provide the "manuals" for both WildSpectra programs.

If you have used an earlier version of WildSpectra. . .
notice that some features have changed!
Read the information on the download page and study the "Help!" items in the menus.
