A dipole loudspeaker for producing sound at bass frequencies. The dipole loudspeaker includes: a diaphragm having a first radiating surface and a second radiating surface, wherein the first radiating surface and the second radiating surface are located on opposite faces of the diaphragm, and wherein the first and second radiating surfaces each have a surface area of at least 100cm 2 ; a drive unit configured to move the diaphragm at bass frequencies such that the first and second radiating surfaces produce sound at bass frequencies, wherein the sound produced by the first radiating surface is in antiphase with sound produced by the second radiating surface; a frame, wherein the diaphragm is suspended from the frame via one or more suspension elements, wherein the frame is configured to allow sound produced by the first radiating surface to propagate out from a first side of the dipole loudspeaker and to allow sound produced by the second radiating surface to propagate out from a second side of the dipole loudspeaker wherein the loudspeaker is for use with an ear of a user being located at a listening position that is in front of the first radiating surface and is 40cm or less from the first radiating surface.

A method for acoustic scene playback comprises: providing recording data comprising microphone signals of one or more microphone setups positioned within an acoustic scene and microphone metadata of the one or more microphone setups, wherein each of the one or more microphone setups comprises one or more microphones and has a recording spot which is a center position of the respective microphone setup; specifying a virtual listening position, wherein the virtual listening position is a position within the acoustic scene; assigning each microphone setup of the one or more microphone setups one or more Virtual Loudspeaker Objects, VLOs, wherein each VLO is an abstract sound output object within a virtual free field; generating an encoded data stream based on the recording data, the virtual listening position and VLO parameters of the VLOs assigned to the one or more microphone setups; and decoding the encoded data stream based on a playback setup, thereby generating a decoded data stream; and feeding the decoded data stream to a rendering device, thereby driving the rendering device to reproduce sound of the acoustic scene at the virtual listening position. A playback apparatus and a computer program for performing the method for acoustic scene playback are also described.

In a particular aspect, a multimedia device includes one or more sensors configured to generate first sensor data and second sensor data. The first sensor data is indicative of a first position at a first time and the second sensor data is indicative of a second position at a second time. The multimedia device further includes a processor coupled to the one or more sensors. The processor is configured to generate a first version of a spatialized audio signal, determine a cumulative value based on an offset, the first position, and the second position, and generate a second version of the spatialized audio signal based on the cumulative value.
