Vladimir Askold Bogdanov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods and apparatus for audio recognition
    Patent number: 8352259
    Abstract: Frequencies from a set of audio source files are extracted and measured across the set to determine a range of each of the frequencies. Stable frequencies of the frequencies are detected based on each range and used to create a stable frequency family. An unknown recording is mapped to the stable frequency family to form an audio fingerprint.

  • Digital audio track set recognition system
    Patent number: 7877408
    Abstract: A system and method are provided for matching a track set from a digital audio recording to metadata relating to the recording. Track duration data is obtained for the track set, and the track duration data is rounded. A search is performed for matching records in a first database based on the rounded track duration data, each resulting matching record having an identifier. Track duration data is retrieved from a second database based on the identifiers associated with the matching records. If more than one matching record is found, the track duration data retrieved from the second database is compared to the track duration data obtained for the track set to find a best matching record of in the second database. Metadata contained in the best matching record of the second database is output.

  • Methods and apparatus for audio recognition
    Patent number: 7567899
    Abstract: A method, apparatus and computer memory are provided for recognizing an audio fingerprint of an unknown audio recording. A database stores a plurality of audio recording identifiers corresponding to a plurality of known audio recordings, where the audio recording identifiers are organized by variation information about the audio recordings. A processor searches a database and identifies at least one of the audio recording identifiers corresponding to the audio fingerprint, where the audio fingerprint includes variation information of the unknown audio recording.

  • Methods and apparatus for identifying media objects
    Patent number: 7451078
    Abstract: A method, apparatus and computer memory are provided for generating an audio fingerprint of an audio recording. A memory stores stable frequency family data corresponding to a plurality of stable frequency families. A processor curve fits audio recording data to at least one of the stable frequency families, extracts at least one variation from the curve fitted audio recording data, and creates the audio fingerprint of the audio recording from the at least one variation.
