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.
