AudioXplorer lets you analyze sound in MacOSX. It can show a sonogram, spectrum, and the sound itself in a visual format. It can generate new sounds, or record a sound to be manipulated. It can export the data in graphics formats, export the audio in AIFF format, and import in sounds in all the major types that you can think of (mp3, mp4, wav, snd, etc). Very cool little application for those that need to generate and manipulate sounds with this Mac. Freeware due to it being discontinued. The source code is available for download under the BSD license.
