Abstract

A method of processing audio may include receiving, by a computing device, a plurality of real-time audio signals outputted by a plurality of microphones communicatively coupled to the computing device. The computing device may output to a display a graphical user interface (GUI) that presents audio information associated with the received audio signals. The one or more received audio signals may be processed based on a user input associated with the audio information presented via the GUI to generate one or more processed audio signals. The one or more processed audio signals may be output to, for example, one or more output devices such as speakers, headsets, and the like.

First claim

What is claimed is:

1. A method of processing audio data, the method comprising:
receiving, by a computing device, a plurality of real-time audio signals from a plurality of microphones communicatively coupled to the computing device, wherein the plurality of real-time audio signals collectively form a surround sound recording (SSR) of the audio data;
determining a type of location associated with the SSR;
determining, based on the type of location associated with the SSR, one or more noise suppression levels with respect to the received plurality of real-time audio signals;
outputting, to a display, a graphical user interface (GUI) that presents one or more noise suppression options corresponding to one or more noise suppression levels of the one or more noise suppression levels determined based on the type of location associated with the SSR;
receiving, via the GUI, a user input indicating a selected noise suppression option from the one or more noise suppression options presented via the GUI;
processing one or more of the received plurality of audio signals based on the respective noise suppression level of the selected noise suppression option to generate a noise-suppressed SSR of the audio data; and
outputting the noise-suppressed SSR of the audio data.

2. The method of claim 1 , further comprising detecting an amount of noise corresponding to one or more of the received plurality of audio signals, wherein determining the one or more noise suppression levels with respect to the received plurality of real-time audio signals comprises determining the one or more noise suppression levels further based on the detected amount of noise.

3. The method of claim 2 , wherein outputting the GUI comprises outputting the GUI to include information related to the detected amount of noise, and the one or more noise suppression options.

4. The method of claim 2 , wherein outputting the GUI comprises outputting the GUI to include a spatial presentation of the information related to the detected amount of noise via a dynamic graphical representation for an audio channel that is configured to change based on one or more changes to a portion of the detected amount of noise corresponding to the audio channel.

5. The method of claim 1 , wherein processing the one or more of the received plurality of audio signals comprises filtering the processed one or more of the received plurality of audio signals based on the respective noise suppression level of the selected noise suppression option.

6. The method of claim 5 , wherein filtering the processed one or more of the received plurality of audio signals comprises attenuating noise data in the processed one or more of the received plurality of audio signals.

7. The method of claim 1 , further comprising:
detecting a scene corresponding to a location of the computing device, wherein determining the type of location comprises determining the type of location based on the detected scene;
determining, based on the type of location, a noise suppression recommendation that corresponds to one of the one or more noise suppression options presented via the GUI; and
presenting the determined noise suppression recommendation via the GUI.

8. The method of claim 7 , wherein detecting the scene comprises detecting the scene based on one or more of an image captured by the computing device using a camera, audio data of one or more of the received plurality of audio signals, one or more global positioning system (GPS) coordinates corresponding to the location of the computing device, or one or more GPS coordinates corresponding to a location of one or more of the plurality of microphones.

9. An apparatus comprising:
an interface configured to receive a plurality of real-time audio signals from a plurality of microphones coupled to the apparatus;
a memory coupled to the interface, the memory being configured to store the received plurality of audio signals; and
one or more processors coupled to the memory, the one or more processors being configured to:
generate a surround sound recording (SSR) of audio data using the plurality of audio signals stored in the memory;
determine a type of location associated with the SSR;
determine, based on the type of location associated with the SSR, one or more noise suppression levels with respect to the plurality of real-time audio signals stored to the memory;
output, for display, graphical content of a graphical user interface (GUI) that presents one or more the noise suppression options corresponding to one or more noise suppression levels of the one or more noise suppression levels determined based on the type of location associated with the SSR;
receive, via the GUI, a user input indicating a selected noise suppression option from the one or more noise suppression options presented via the GUI;
process one or more of the plurality of audio signals stored to the memory based on the respective noise suppression level of the selected noise suppression option to generate a noise-suppressed SSR of the audio data; and
output the noise-suppressed SSR of the audio data.

10. The apparatus of claim 9 , wherein the one or more processors are configured to detect an amount of noise corresponding to one or more of the plurality of audio signals stored to the memory, and wherein to determine the one or more noise suppression of with respect to the plurality of real-time audio signals, the one or more processors are configured to determine the one or more noise suppression levels further based on the detected amount of noise.

11. The apparatus of claim 10 , wherein to output the GUI, the one or more processors are configured to output the GUI to include information related to the detected amount of noise, and the one or more noise suppression options.

12. The apparatus of claim 10 , wherein to output the GUI, the one or more processors are configured to output the GUI to include a spatial presentation of the information related to the detected amount of noise via a dynamic graphical representation for an audio channel that is configured to change based on one or more changes to a portion of the detected amount of noise corresponding to the audio channel.

13. The apparatus of claim 9 , wherein to process the one or more of the plurality of audio signals stored to the memory, the one or more processors are configured to filter the processed one or more of the plurality of audio signals stored to the memory based on the respective noise suppression level of the selected noise suppression option.

14. The apparatus of claim 13 , wherein to filter the one or more of the plurality of audio signals stored to the memory, the one or more processors are configured to attenuate noise data in the one or more of the plurality of audio signals stored in the memory.

15. The apparatus of claim 9 , wherein the one or more processors are further configured to:
detect a scene corresponding to a location of the computing device, wherein to determine the type of location, the one or more processors are configured to determine the type of location based on the detected scene;
determine, based on the type of location, a noise suppression recommendation that corresponds to one of the one or more noise suppression options presented via the GUI; and
present the determined noise suppression recommendation via the GUI.

16. The apparatus of claim 15 , wherein the one or more processors are configured to detect the scene based on one or more of an image captured by a camera coupled to the computing device, audio data of the one or more of the plurality of audio signal
