Systems and methods for equalizing audio for playback on an electronic device
Embodiments are provided for equalizing audio data for output by a speaker of an electronic device based on a local position or orientation of the electronic device. According to certain aspects, the electronic device can determine ( 858, 868 ) its local position based on various sensor data, and identify ( 870, 872 ) an appropriate equalization setting. In some cases, the electronic device can modify ( 876, 880 ) the equalization setting based on acoustic and/or optical data. The electronic device can apply ( 882 ) the modified or unmodified equalization setting to an audio signal and cause the speaker to output ( 886 ) the audio signal with the applied equalization setting.

5. The method of claim 4 , further comprising:
determining, based on the data from the sensor, a change in the position tilt of the user relative to the speaker;
modifying, based on the change in the position tilt of the user relative to the speaker, the second equalization setting to generate a third equalization setting; and
providing, for output at the speaker of the electronic device, a third audio signal with the third equalization setting.
6. The method of claim 1 , wherein determining whether the speaker of the electronic device is facing substantially towards or away from the support surface comprises determining that a speaker grille of the speaker is facing substantially towards or away from the support surface.
