Most music comes with some visualization, generally in the form of an album cover. The files at freesound.org come with waveform graphics, as shown below. The freesound.org site is a community for field-recording enthusiasts and, in the site’s dedicated “Remix! tree” section, the people who love to remix the publicly available source material. A recent case in point is this elegant waveform, which looks like the declining moments of a guest at your local ICU:
In fact, what’s shown above is a stereo recording of scratching, as posted on the site (freesound.org, MP3) back in March 2005 by a member who goes by Edgar.
