RavenViewer

RavenViewer is a free QuickTime audio visualization tool.

• Play AND visualize digital audio recordings (ours, and soon your own)
• Watch spectrograms (graphs of frequency vs. time), power spectra and waveforms. RavenViewer creates these views in real time and scrolls them as the recording plays
• Watch video and simultaneously visualize the sound track
• Control zoom, playback speed, resolution, & more
• Customize with your own colors, brightness, and contrast
• Inspect low-frequency sounds that are inaudible to humans
• Experience sound in a new way
