Abstract

Claims (34)

1. A computing device, comprising:

a processor; and

an enhance audio mode executable on the processor, the processor configured to:

cause to be received, into a memory, a sample of an audio component of one or more digital media streams from a specific media streaming application;

cause conversion, with a digital-to-analog converter, of the one or more digital media streams into corresponding one or more analog media streams;

analyze an amplitude of the audio component of the one or more analog media streams from the specific media streaming application; and

cause a volume gain adjustment to be applied to the audio component of the one or more analog media streams from the specific media streaming application, the volume gain adjustment based on the analyzed amplitude of the audio component.

2. The device of claim 1 wherein the volume gain adjustment is applied by an audio codec.

3. The device of claim 1 wherein the volume gain adjustment is applied upon detection of playback of the one or more analog media streams by the specific media streaming application in a kernel space level.

4. The device of claim 1 further comprising one or more speakers, wherein the volume gain adjustment is further calculated based on the specifications of the one or more speakers.

5. The device of claim 1 wherein the enhance audio mode is further configured to detect playback of the one or more media streams from the specific media streaming application based on a system file update.

6. The device of claim 5 wherein the system file update occurs at a user space level.

7. The device of claim 1 wherein the volume gain adjustment increases the volume gain for all audio components of the one or more analog media streams played using the specific media streaming application.

8. The device of claim 1 wherein the enhance audio mode is further configured to operate with a plurality of specific media streaming applications, and each specific media streaming application of the plurality has a different corresponding volume gain adjustment.

9. The device of claim 8 wherein the volume gain adjustment for a specific media streaming application of the plurality of specific media streaming applications is retrieved from a table upon playback from the specific application.

10. The device of claim 1 wherein the enhance audio mode is further configured to apply a first volume gain adjustment if the audio component of the one or more analog media streams is being output to one or more speakers of the computing device, and a second volume gain adjustment if the audio component of the one or more media streams is being output to a headphone jack of the computing device.

11. The device of claim 1 wherein the enhance audio mode is user-configurable.

12. A non-transitory computer program product stored on a non-transitory computer-readable medium that includes a plurality of instructions that, when loaded into memory, cause a processor to perform a method, the method comprising:

in response to playback of one or more digital media streams from a specific media streaming application, invoke an enhance audio mode configured to:

sample an audio component of the one or more digital media streams from the specific media streaming application;

cause conversion, using a digital-to-analog converter, of the one or more digital media streams into corresponding one or more analog media streams;

analyze an amplitude of the audio component of the one or more analog media streams from the specific media streaming application;

apply a volume gain adjustment to the audio component of the one or more analog media streams from the specific media streaming application, the volume gain adjustment applied based on the analyzed amplitude of the audio component.

13. The non-transitory computer program product of claim 12 wherein the volume gain adjustment is applied by an audio codec.

14. The non-transitory computer program product of claim 12 wherein the volume gain adjustment is a single adjustment in the range of −10 decibels to +10 decibels.

15. The non-transitory computer program product of claim 12 wherein the process is further configured to apply a default volume gain in response to a stoppage in the playback of the one or more analog media streams from the specific media streaming application.

16. The non-transitory computer program product of claim 12 wherein the enhance audio mode is further configured to operate with a plurality of specific media streaming applications, and each specific media streaming application of the plurality has a different corresponding volume gain adjustment.

17. A non-transitory computer program product stored on a non-transitory computer-readable medium that includes a plurality of instructions that, when loaded into memory, cause a processor to perform a method, the method comprising:

sample an audio component of one or more media streams from a specific media streaming application;

analyze an amplitude of the audio component of the one or more media streams from the specific media streaming application;

update an entry in a system file in a user space level of the electronic device upon detection of the one or more media streams from the specific media streaming application;

perform a volume gain adjustment to the audio component of the one or more media streams from the specific media streaming application upon detection of the of the specific media streaming application in a kernel space level of the electronic device, the volume gain adjustment based on the analyzed amplitude of the audio component; and

forward the audio component of the one or more media streams to an audio output.

18. The non-transitory computer program product of claim 17 wherein the audio output is one of one or more speakers and a headphone jack.
