Abstract
One embodiment provides a method, including: receiving, at a device employing two or more audio capture devices, an audio signal; determining a distance between two of the two or more audio capture devices capturing the audio signal; and reducing, using a noise cancellation technique employing the determined distance, an amount of unwanted noise from the audio signal. Other aspects are described and claimed.
Claims19
A method, comprising:
- receiving, at a device employing two or more audio capture devices, an audio signal;
- determining, at substantially the time of receipt of the audio signal, a distance between two of the two or more audio capture devices capturing the audio signal, wherein the determined distance comprises a distance between the two or more audio capture devices at the time of receipt of the audio signal, wherein the determined distance is variable between receipt of audio signals;
- and
- reducing, using a noise cancellation technique that is based upon the distance being variable and that employs the determined distance, an amount of unwanted noise from the audio signal.
1 more element
An information handling device, comprising:
- two or more audio capture devices;
- a processor operatively coupled to the two or more audio capture devices;
- a memory device that stores instructions executable by the processor to:
- receive, at the two or more audio capture devices, an audio signal;
- determine, at substantially the time of receipt of the audio signal, a distance between two of the two or more audio capture devices capturing the audio signal, wherein the determined distance comprises a distance between the two or more audio capture devices at the time of receipt of the audio signal, wherein the determined distance is variable between receipt of audio signals;
- and
- reduce, using a noise cancellation technique that is based upon the distance being variable and that employs the determined distance, an amount of unwanted noise from the audio signal.
4 more elements
A product, comprising:
- a storage device that stores code, the code being executable by a processor and comprising:
- code that receives, at a device employing two or more audio capture devices, an audio signal;
- code that determines, at substantially the time of receipt of the audio signal, a distance between two of the two or more audio capture devices capturing the audio signal, wherein the determined distance comprises a distance between the two or more audio capture devices at the time of receipt of the audio signal, wherein the determined distance is variable between receipt of audio signals;
- and
- code that reduces, using a noise cancellation technique that is based upon the distance being variable and that employs the determined distance, an amount of unwanted noise from the audio signal.
