Title
(EN) SOUND FIELD ADJUSTMENT
Abstract
(EN)

A device includes one or more processors configured to obtain sound information from an audio source. The one or more processors are further configured to select, based on a latency criterion associated with a playback device, a compression mode in which a representation of the sound information is compressed prior to transmission to the playback device or a bypass mode in which the representation of the sound information is not compressed prior to transmission to the playback device. The one or more processors are further configured to generate audio data that includes, based on the selected one of the compression mode or the bypass mode, a compressed representation of the sound information or an uncompressed representation of the sound information. The one or more processors are also configured to send the audio data as streaming data, via wireless transmission, to the playback device.
