improved method for delivery and play back of sound and image files is provided. This new method includes the use of sound and / or image clips, which can be snippets or full files, as alerts for a variety of electronic devices or for playing on a handheld device, and for use as a promotion to sell items associated with the files. A collection or
library of uniquely selected and / or edited clips may also be provided to the
consumer in a manner far more conveniently on conventional
telephone equipment than previously available. Algorithms are provided for the delivery, storage and playback of the sound files, including a delivery method
algorithm (500), a parametric optimization and compression
