The present invention discloses method and system of encoding audio information (e.g., music, speech, etc.) from an analog medium (e.g., vinyl recordings, cassette tapes, etc.) into a compressed, track-oriented, digital format using attribute information and silence detection. The invention generates an analog audio signal by reproducing the audio information recorded on the analog medium, which is recorded on a plurality of discrete analog tracks. The analog audio signal is then sampled to generate a digital audio file (i.e., WAV file). The digital audio file is filtered to correct defects and then separated into a plurality of discrete digital audio tracks. Attribute information, such as track length, is accessed and confirmed by silence detection techniques in order to provide separation. This separation is accomplished such that each of the discrete digital audio tracks contains audio information corresponding to each of the discrete analog tracks, and are thus, arranged in a track-oriented digital format. The discrete digital audio tracks are then compressed (e.g., MP3) and stored, thereby providing reliable and readily accessible audio information.
