  • Panning of audio objects to arbitrary speaker layouts
    Patent number: 9712939
    Abstract: A gain contribution of the audio signal for each of the N audio objects to at least one of M speakers may be determined. Determining the gain contribution may involve determining a center of loudness position that is a function of speaker (or cluster) positions and gains assigned to each speaker (or cluster). Determining the gain contribution also may involve determining a minimum value of a cost function. A first term of the cost function may represent a difference between the center of loudness position and an audio object position.

  • MULTI-CHANNEL AUDIO CODING
    Publication number: 20100153097
    Abstract: A multi-channel audio encoder (10) for encoding a multi-channel audio signal (101), e.g. a 5.1 channel audio signal, into a spatial down-mix (102), e.g. a stereo signal, and associated parameters (104, 105). The encoder (10) comprises first and second units (110, 120). The first unit (110) encodes the multi-channel audio signal (101) into the spatial down-mix (102) and parameters (104). These parameters (104) enable a multi-channel decoder (20) to reconstruct the multi-channel audio signal (203) from the spatial down-mix (102). The second unit (120) generates, from the spatial down-mix (102), parameters (105) that enable the decoder to reconstruct the spatial down-mix (202) from an alternative down-mix (103), e.g. a so-called artistic down-mix that has been manually mixed in a sound studio. In this way, the decoder (20) can efficiently deal with a situation in which an alternative down-mix (103) is received instead of the regular spatial, down-mix (102).
