  • Patent number: 8966394
    Abstract: System, method and computer program for facilitating media playlist generation based at least in part on media library inventory information provided by a plurality of program participants. Data is transmitted from a program participant's client device indicative of media inventory in a media library of the program participant. Media item similarity ratings are received at the client device that have been compiled based on cumulative data collected from a plurality of program participants, including identification data of individual media items contained in media libraries of the program participants regardless of each individual media item's source. Similarity ratings compilation includes processing the cumulative data to determine an incidence of co-occurrence of pairs of individual media items in different program participants' media libraries and making an assignment of a similarity rating based on the determined incidence of co-occurrence.

  • Patent number: 8914384
    Abstract: System, method and computer program that encompasses one or more client devices cooperating with a program host's on-line data processing center to generate media playlists. Data is transmitted from a program participant's client device to the processing center and is representative of media inventory in a media library on the client device and includes identification data of contained individual media items. Data is further received from a plurality of program participants representative of each respective program participant's media inventory, regardless of the source of the members of the inventory. Co-occurrence of pairs of individual media items in different program participants' media libraries is determined and a similarity rating is assigned between the pairs of individual media items based on the determined incidence of co-occurrence in the different program participants' media libraries. From this, a media playlist is generated.

  • Publication number: 20080077262
    Abstract: Distortion free stitching of two temporally adjacent digital media files of any format or origin is described. Two digital media files are selected and placed temporally adjacent to each other. A determination is then made of the direction of each of the waveforms and an associated delta value between a last audio sample of a first to be played media file and a first audio sample of a next to be played media file. A stitching operation is performed, or not, based upon the respective directions of the waveforms and the associated delta value.

  • Patent number: 7177431
    Abstract: A system and method are described for rendering a left rear surround input signal at a left rear virtual speaker location and rendering a right rear surround input signal at a right rear virtual speaker location. The method includes phase shifting the left rear surround input signal by a first phase shift. The right rear surround input signal is phase shifted by a second phase shift. The phase shifted left rear surround input signal is phase shifted using an HRTF selected to render the left rear surround input signal at the left rear virtual speaker location. The phase shifted right rear surround input signal is transformed using an HRTF selected to render the right rear surround input signal at the right rear virtual speaker location.
