Audio control based on orientation

A device, comprising:

• device orientation detection circuitry configured to determine device orientation with respect to a coordinate system;
• user head orientation detection circuitry configured to determine user head orientation with respect to the device;
• and
• audio adjustment circuitry configured to control the generation of an audio signal based on the device orientation and user head orientation.

A method, comprising:

• determining device orientation with respect to a coordinate system;
• determining user head orientation with respect to the device;
• and
• controlling generation of an audio signal based on the device orientation and user head orientation.

A system comprising at least one machine-readable storage medium having stored thereon, individually or in combination, instructions that when executed by one or more processors result in the following operations comprising:

• determining device orientation with respect to a coordinate system;
• determining user head orientation with respect to the device;
• and
• controlling generation of an audio signal based on the device orientation and user head orientation.
