Overview of the MPEG-7 Standard: MPEG-7, formally named "Multimedia Content Description Interface", aims to create a standard for describing the multimedia content data that will support some degree of interpretation of the information's meaning, which can be passed onto, or accessed by, a device or a computer code. MPEG-7 is not aimed at any one application in particular; rather, the elements that MPEG-7 standardises shall support as broad a range of applications as possible.

A Small SHN and MD5 FAQ: Shorten (extension .shn) is an audio compression scheme written by Tony Robinson of SoftSound that can compact wav files without subtracting out any frequencies. It's "lossless"- everything in the original wav is there, so that full quality is maintained. For many traders of live music, Shorten files (shns) therefore have an undisputed advantage over "lossy" mp3-format files. A shn file made from a wav is quite a bit larger than the corresponding mp3, with a size perhaps ~50-60% of the orginal wav.

Some SHN Resources: Here are some communities that are either familiar with or actively promote trading music of trade-friendly bands in Shorten (SHN) format. If you know of other relevant sites or groups, please drop us a line. We will not list any resources for "trade unfriendly" bands. Please respect the artists, thanks!
