Method and System for Identifying a Media Program From an Audio Signal Associated With the Media Program |
摘要 |
A method of identifying a media program from its associated audio signal comprising dividing a portion of the range of human-audible frequencies in a quasi-logarithmic fashion into a plurality of spectral bands; recording a segment of predetermined length from the audio signal at a predetermined interval to obtain a plurality of analog audio samples, the predetermined interval being a fraction of the predetermined length; converting each analog audio sample to a plurality of digital audio samples at a first sampling rate; creating a frequency domain representation of each digital audio sample; determining spectral energy within each spectral band for each digital audio sample; reflecting whether the spectral energy within each spectral band went up between adjacent ones of the plurality of digital samples as a Boolean array; and representing the audio signal with a predetermined number of Boolean arrays. A confidence score for each value can then be calculated. |
