Abstract
An apparatus comprising: an input configured to receive at least two audio signals, the at least two audio signals having a relative displacement between them; an orientation determiner configured to determine an audio capture orientation based on a device orientation and information concerning microphone configuration in the apparatus; and an audio output generator configured to output the at least two audio signals based on the capture orientation, such that playback of the at least two audio signals is performed based on the capture orientation.
Claims21
A method comprising:
- generating at least two audio signals respectively from at least two microphones, a first of the at least two audio signals captured at a first microphone positioned at a first location and a second of the at least two audio signals captured at a second microphone positioned at a second location, the first microphone having a relative displacement with respect to the second microphone;
- determining an audio capture orientation based on location information of the at least two microphones, the audio capture orientation being associated with the at least two audio signals from the at least two microphones including the relative displacement between the first microphone and the second microphone,
- wherein the audio capture orientation or an indication associated with the audio capture orientation enables playback of the at least two audio signals to be processed based on the audio capture orientation or the indication associated with the audio capture orientation such that the playback of the at least two audio signals is aligned to an arrangement of the at least two microphones when capturing the at least two audio signals;
- and
- reproducing the at least two audio signals having the aligned arrangement during playback.
A method comprising:
- receiving, by a playback device, at least two audio signals respectively from at least two microphones with audio capture orientation information, the audio capture orientation information being associated with the at least two audio signals from the at least two microphones including a relative displacement between a first microphone and a second microphone, wherein a first of the at least two audio signals is captured at the first microphone positioned at a first location and a second of the at least two audio signals is captured at the second microphone positioned at a second location, the first microphone having the relative displacement with respect to the second microphone,
- wherein the audio capture orientation information or an indication associated with the audio capture orientation information enables playback of at least two speakers to be processed based on the audio capture orientation information or the indication associated with the audio capture orientation information
- such that playback of the at least two audio signals is aligned to an arrangement of the at least two microphones when capturing the at least two audio signals;
- and
- reproducing the at least two audio signals for outputting to the at least two speakers having the aligned arrangement during playback.
An apparatus comprising at least one processor and at least one memory including computer code for one or more programs, the at least one memory and the computer code configured to with the at least one processor cause the apparatus to at least:
- generate at least two audio signals respectively from at least two microphones, a first of the at least two audio signals captured at a first microphone positioned at a first location and a second of the at least two audio signals captured at a second microphone positioned at a second location, the first microphone having a relative displacement with respect to the second microphone;
- determine an audio capture orientation based on location information of the at least two microphones, the audio capture orientation being associated with the at least two audio signals from the at least two microphones including the relative displacement between the first microphone and the second microphone,
- wherein the audio capture orientation or an indication associated with the audio capture orientation enables playback of the at least two audio signals to be processed based on the audio capture orientation or the indication associated with the audio capture orientation such that the playback of the at least two audio signals is aligned to an arrangement of the at least two microphones when capturing the at least two audio signals;
- and
- reproduce the at least two audio signals having the aligned arrangement during playback.
An apparatus comprising at least one processor and at least one memory including computer code for one or more programs, the at least one memory and the computer code configured to with the at least one processor cause the apparatus to:
- receive at least two audio signals respectively from at least two microphones with audio capture orientation information, the audio capture orientation information being associated with the at least two audio signals from the at least two microphones including a relative displacement between a first microphone and a second microphone, wherein a first of the at least two audio signals is captured at the first microphone positioned at a first location and a second of the at least two audio signals is captured at the second microphone positioned at a second location, the first microphone having the relative displacement with respect to the second microphone,
- wherein the audio capture orientation information or an indication associated with the audio capture orientation information enables playback of at least two speakers to be processed based on the audio capture orientation information or the indication associated with the audio capture orientation information such that playback of the at least two audio signals is aligned to an arrangement of the at least two microphones when capturing the at least two audio signals;
- and
- reproduce the at least two audio signals for outputting to the at least two speakers having the aligned arrangement during playback.
