Abstract
An apparatus comprising: a receiver configured to receive at least one audio signal from a recording apparatus; the receiver further configured to receive at least one orientation indicator from the recording apparatus, each orientation indicator associated with one at least audio signal; a recording direction determiner configured to determine a recording orientation of the recording apparatus dependent on the at least one audio signal; a relative distance determiner configured to determining a relative distance of the recording apparatus from a sound source dependent on the at least one audio signal; and a relative position determiner configured to determining a relative position of the recording apparatus dependent on the orientation indicator and relative distance.
Claims18
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:
- receive at least one audio signal from a recording apparatus;
- receive at least one orientation indicator from the recording apparatus, each orientation indicator associated with the at least one audio signal;
- determine a direction of the recording apparatus dependent on the each orientation indicator associated with the one at least audio signal;
- determine a sound direction vector for a sound recorded by the recording apparatus, wherein the sound direction vector is dependent on an energy spectrum for the at least one audio signal from the recording apparatus and the at least one orientation indicator received from the recording apparatus;
- and
- determine a virtual position of the recording apparatus from a sound source by the apparatus being caused to determine an average audio signal level of the at least one audio signal from the recording apparatus and at least one further audio signal from a further recording apparatus, and map the at least one audio signal to a relative distance dependent on a signal level of the at least one audio signal compared against the average audio signal level.
A method comprising:
- receiving at least one audio signal from a recording apparatus;
- receiving at least one orientation indicator from the recording apparatus, each orientation indicator associated with the at least one audio signal;
- determining a direction of the recording apparatus dependent on the each orientation indicator associated with the one at least audio signal;
- determining a sound direction vector for a sound recorded by the recording apparatus, wherein the sound direction vector is dependent on an energy spectrum for the at least one audio signal from the recording apparatus and the at least one orientation indicator received from the recording apparatus;
- and
- determining a virtual position of the recording apparatus from a sound source by the apparatus being caused to determine an average audio signal level of the at least one audio signal from the recording apparatus and at least one further audio signal from a further recording apparatus, and map the at least one audio signal to a relative distance dependent on a signal level of the at least one audio signal compared against the average audio signal level.
A computer program product comprising a non-transitory computer-readable medium bearing computer program code embodied therein, the computer program code configured to cause an apparatus at least to perform:
- receiving at least one audio signal from a recording apparatus;
- receiving at least one orientation indicator from the recording apparatus, each orientation indicator associated with the at least one audio signal;
- determining a direction of the recording apparatus dependent on the each orientation indicator associated with the one at least audio signal;
- determining a sound direction vector for a sound recorded by the recording apparatus, wherein the sound direction vector is dependent on an energy spectrum for the at least one audio signal from the recording apparatus and the at least one orientation indicator received from the recording apparatus;
- and
- determining a virtual position of the recording apparatus from a sound source by the apparatus being caused to determine an average audio signal level of the at least one audio signal from the recording apparatus and at least one further audio signal from a further recording apparatus, and map the at least one audio signal to a relative distance dependent on a signal level of the at least one audio signal compared against the average audio signal.
