Digitizing analog audio data
First Claim
1. An apparatus for digitally recording an analog audio signal derived from a commercial album, in which said album has a plurality of tracks, comprising:
- an analog to digital converter for digitizing said analog audio signal;
a digital storage device for storing a digital output signal from said analog to digital converter; and
a processing device for analyzing said digital output signal to identify individual tracks and writing individual digitized tracks of said digital output signal to said digital storage device, wherein said processing device is configured to;
produce a plurality of digitized segments;
obtain one or more track-titles from a remote audio finger-printing service for each digitized segment;
request an album-title for each album on which an obtained track-title appears to provide candidate albums from said remote audio finger-printing service;
generate a score for the each provided candidate album based on the number of obtained track-titles that appear on each said candidate album;
compare each track-title with the obtained track-titles wherein the respective score is incremented for each matched track title for each candidate album;
identify an album from said incremented scores, wherein the identified album has the highest incremented score from the candidate albums; and
store said digital output signal as individual tracks with reference to said identified album.

Abstract
A commercial album of analog audio recordings, having multiple tracks, is identified. An analog recording of the album is played to produce an analog audio input signal. The audio output signal is digitally sampled to produce digitized segments. One or more track-titles are obtained (1902) from a remote audio finger-printing service for each digitized segment to provide track-titles. For each obtained track-title, each album-title is requested (1905) upon which the obtained track-title appears, to provide candidate albums. A score is generated (1905) for each provided candidate album based on the number of obtained track-titles that appear on a provided candidate album in the correct order. An album is identified by comparing (2209) these scores.

11. A method of identifying a commercial album of analog audio recordings, in which an album has a plurality of recorded tracks, comprising the steps of:
-
playing an analog recording of said album to produce an analog audio input signal; digitally sampling said audio input signal to produce a digital output signal; storing said digital output signal; and analyzing said digital output signal to identify individual tracks and writing individual digitized tracks of said digital output signal to a digital storage device, by further comprising the steps of; (a) producing a plurality of digitized segments from said digital output signal; (b) obtaining one or more track titles from a remote audio finger-printing service for each said digitized segment; (c) requesting an album title for each album on which an obtained track title appears, to provide candidate albums from said remote audio finger-printing service; (d) generating a score for each provided candidate album based on the number of obtained track titles that appear on each said candidate album; (e) comparing each track title with the obtained track titles, wherein the respective score is incremented for each matched track title for each candidate album; (f) identifying an album from said incremented scores, wherein the identified album has the highest incremented score from the candidate albums; and (g) storing said digital output signal as individual tracks with reference to said identified album. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
