Abstract (en)

Systems and methods for recording and synthesizing sound in a resolution-independent manner and infrastructures for distributing resolution-independent recordings for remote playback. In one embodiment, one system includes: a frame generator (130) that extracts fundamental frequencies and spectral envelopes from the sound and creates frames therefrom and a frame analyzer (140) that identifies a selected one of common spectra structures and common formant structures in the frames and creates a record containing the fundamental frequencies and the selected one. One infrastructure includes: a radio station having a recording database associated therewith, a plurality of recordings contained within the recording database, each of the plurality of recordings including the selected one, a request receiver, coupled to the recording database, that receives remote requests for ones of the plurality of recordings and a transmitter, coupled to the recording database, that transmits the ones of the plurality of recordings in response to the requests. <IMAGE>
