Abstract: The present technology relates to an audio signal reproduction apparatus and a reproduction method, a sound pickup apparatus and a sound pickup method, and a program capable of matching listening timing from individual speakers at a listening position with a simpler configuration.There is provided an audio signal reproduction apparatus including: a reproduction unit that reproduces an audio signal supplied to a speaker installed to be directed to a listening position; and an adjustment unit that adjusts a delay amount of the audio signal supplied to a target speaker in accordance with an interval of a measurement sound obtained from a picked-up signal with another speaker. The picked-up signal is a measurement sound picked up by a sound pickup apparatus installed at the listening position and is a signal including the measurement sound corresponding to a measurement signal, and the measurement signal is a signal that causes a plurality of speakers installed to be directed to the listening position to output the measurement sound at a predetermined time interval. The present technology can be applied to an audio signal reproduction apparatus such as an AV amplifier device and a wireless speaker.

Abstract: Provided is a natural surround sound field balanced in volume in a multichannel surround reproduction environment, regardless of the positions of speakers actually disposed. Arrangement position information on real speakers is acquired. Based on the arrangement position information, a target position of a virtual speaker corresponding to a real speaker is set such that the virtual speaker is disposed in or near an ideal disposition area of the real speaker. The ideal disposition area of the real speaker is an area corresponding to the arrangement position of the speaker at the time of creation of a sound source. Based on the target position of the virtual speaker, the disposition of the virtual speaker is controlled.

Abstract translation: 提供了在多声道环绕重放环境中平衡体积的自然环绕声场，而不管实际放置的扬声器的位置如何。 获取有关真实扬声器的排列位置信息。 基于排列位置信息，设置与真实扬声器对应的虚拟扬声器的目标位置，使得虚拟扬声器设置在真实扬声器的理想配置区域中或附近。 真正的扬声器的理想配置区域是在创建声源时与扬声器的布置位置对应的区域。 基于虚拟扬声器的目标位置，控制虚拟扬声器的配置。
