Automated detection of an active audio output
First Claim
1. A method for automatically detecting an active audio output of an audio playback device, comprising:
- playing back audio content on the audio playback device;
capturing sound during audio content playback using an audio capture device in communication with the audio playback device;
analyzing whether the captured sound matches the audio playing back on the audio playback device to generate an analysis; and
determining the active audio output of the audio playback device based on the analysis;
wherein the audio capture device is a microphone on the audio playback device.

Abstract
An active audio output detection system and method that automatically determines the type of audio output being used on an audio playback device. Embodiments of the system and method include playing back audio content on the audio playback device (such as a mobile phone) and capturing sound during playback using an audio capture device (such as a microphone). The captured sound is analyzed to determine whether the audio playing back on the audio playback device is contained therein. If the captured sound matches the audio playing back on the audio playback device, then the active audio output is a loudspeaker. On the other hand, if the captured sound does not match the audio playing back on the audio playback device, then the active audio output is headphones.

11. A method for determining a type of audio reproduction device in communication with an audio playback device, comprising:
-
playing back audio content on the audio playback device over the audio reproduction device; capturing sound during the audio content playback; listening for the audio content in the sound captured during the audio content playback using an audio capture device to determine whether the audio content being played back is present; determining that the type of audio reproduction device is a loudspeaker if the audio content is present; and determining that the type of audio reproduction device is headphones if the audio content is not present. - View Dependent Claims (12, 13)

14. A system for automatically determining a type of audio reproduction device connected to a mobile phone, comprising:
-
audio content that is played back on the mobile phone through the audio reproduction device; an audio capture device that captures sound while the audio content is being played back; an analysis processor that performs an analysis as to whether the audio content is present in the captured sound; and a selection processor that determines the type of audio reproduction device based on the analysis. - View Dependent Claims (15, 16)
