摘要： There is provided a method, comprising: receiving (905) an input audio signal (X) comprising a left input channel (XL) and a right input channel (XR); generating (910) a spatially enhanced left channel (YL) and a spatially enhanced right channel (YR) by: dividing the left input channel (XL) and the right input channel (XR) into left subband components and right subband components, and converting the left subband components and right subband components into a side channel including side subband components and a first mid channel including mid subband components, each of the side subband components corresponding to one frequency band from a group of frequency bands, each of the mid subband components corresponding to one frequency band from the group of frequency bands; generating a spatially enhanced side component and a spatially enhanced mid component by, for each frequency band of the group of frequency bands, applying a first gain and a first delay to a side subband component of the frequency band and a second gain different from the first gain to a mid subband component of the frequency band; and converting the spatially enhanced side component and the spatially enhanced mid component into the spatially enhanced left channel (YL) and the spatially enhanced right channel (YR); generating (915) a left crosstalk channel by filtering and time delaying the left input channel (XL); generating (915) a right crosstalk channel by filtering and time delaying the right input channel (XR); generating (940) a left output channel (OL) by mixing the spatially enhanced left channel (YL) and the right crosstalk channel; and generating (940) a right output channel (OR) by mixing the spatially enhanced right channel (YR) and the left crosstalk channel.

摘要： Embodiments relate to providing a conference for client devices with spatialized audio. Input audio streams are received from the client devices. For each client device, placement data defining spatial locations of other client devices within a sound field is determined. A mixed stream including a left mixed channel and a right mixed channel for the client device is generated by mixing and panning input audio streams of the other client devices according to the placement data. A spatially enhanced stream including a left enhanced channel for a left speaker and a right enhanced channel for a right speaker is generated by applying subband spatial processing and crosstalk processing on the left mixed channel and the right mixed channel of the mixed stream.
