摘要： A playback apparatus includes a forming section which, on the basis of an audio signal to be played back, forms audio signals on a plurality of channels for emitting sounds from a pair of sound sources, and a signal processing section which, on each of the audio signals formed by the forming section, performs signal processing for forming a targeted sound field. The signal processing section inclines a sound pressure distribution so that, for each sound source, sound pressure levels of sounds emitted from the sound source to a listening position increase in inverse proportion to angles formed between emitting directions of the sounds emitted from the sound source to the listening position and a straight line connecting the pair of sound sources.

摘要： A sound reproduction apparatus capable of providing a target sensation of sound localization to a listener by using a standard head-related transfer function is provided. In a microphone amplifying section, only the high frequency components of a left sound pickup signal and a right sound pickup signal, which are input from a dummy head microphone, are delayed by a delay circuit. Consequently, since the reproduction sound of the low frequency components having small individual differences can be output earlier, a listener in a reproduction sound field space can perceive the sensation of sound localization by the reproduction sound of the low frequency components that arrive earlier. As a result, even when a standard head-related transfer function is used, it becomes possible to enable the listener in the reproduction sound field space to perceive the target sensation of sound localization.

摘要： A sound field reproduction apparatus generates sound field synthesizing parameters according to a relative positional relationship between the listener and the sound source and performs frequency conversion on sound data according to the relative positional relationship. A convolutional operation is conducted on the sound data that are subjected to the frequency conversion and the generated sound field synthesizing parameters in order to synthesize the sound of the sound source of each channel. The synthesized sound is subjected to wave front synthesis for the synthesized sound by using n-channel sound sources to reproduce a sound field in a predetermined area.
