摘要： Examples of the disclosure relate to apparatus, methods and computer programs for enabling audio zooming. The apparatus can comprise means for determining, for an audio signal, if sound energy in at least one first direction is different to sound energy in at least one second direction by at least a threshold amount. The means may also be for controlling an amount of headroom provided based on whether or not sound energy in at least one first direction is different to the sound energy in at least one second direction by at least a threshold amount.

摘要： According to an aspect, there is provided an apparatus for a wearable terminal device comprising means for performing the following. The apparatus receives, via a bone conduction sensor, a bone conduction signal and, via at least one microphone over the air, an audio signal. The bone conduction signal and the audio signal are, at least in part, substantially concurrently recorded signals. The apparatus calculates a value of a similarity metric for evaluating an extent of similarity between the bone conduction and audio signals. In response to the value exceeding a predefined threshold, the apparatus causes performing one or more actions comprising executing, in response to detecting a voice command, the voice command and/or modifying, if the audio signal is received via a plurality of microphones over the air, one or more audio focusing parameters of the plurality of microphones for increasing the value of the similarity metric.

摘要： Audio data and associated classification data from a plurality of user devices as part of a conference call is provided, the plurality of user devices including at least a first user device and a second user device. The classification data is indicative of one of a plurality of predetermined sound types represented by the associated audio data in a current time frame. Determining that the audio data provided by the first user device is associated with a prioritised dominant speaker. Controlling transmission of the audio data as part of the conference call and preventing transmission of audio data provided by at least the second user device based on its associated classification data being indicative of a restricted sound type for example silence, background noise, coughing, emotive sound, singing or interjections type of sound and the first user device being associated with the dominant speaker.

摘要： An apparatus comprising means configured to: obtain an object track and an ambience track; obtain a control value configured to control the relative levels of the object track and the ambience track; estimate a leakage between the object track and the ambience track; determine at least one leakage level gain control value based on the control value and the leakage; and apply the at least one leakage level gain value to at least one of: the object track; and the ambience track, the application of the at least one leakage level gain value is such that a rendered audio signal is based on the application of the at least one leakage level gain control value to at least one of: the object track; and the ambience track.
