Claims:1. A device, comprising:
an audio processor configured to perform audio processing during an audio communication connection between a first communication device and a second communication device;
a memory configured to store at least a first audio processor wakeup schedule in accordance with a first predefined audio communication connection event;
a controller configured to
set at least one second audio processor wakeup schedule based on a second predefined audio communication connection event being similar to the first audio processor wakeup schedule, and
send a wake up signal to the audio processor to wake up the audio processor based on at least one of the first audio processor wakeup schedule or the second audio processor wakeup schedule in response to at least one of the first or second predefined audio communication connection events;
wherein the audio processor is further configured to enter into a sleep mode after the audio processing is complete and to enter into a processing mode from the sleep mode in response to the wake up signal.
, Description:Technical Field
Embodiments described herein generally relate to devices and methods for processing audio data.
Background
Mobile phones are typically used for calls between their users. Such a call involves audio processing such as encoding and decoding of audio data carried out by some audio processing component. Typically, such an audio processing component has sufficient computational power to be able to perform the audio processing in short time intervals and can enter sleep mode between these intervals. In terms of power consumption, it is desirable to keep the number and the length of wakeups from sleep mode as low as possible.

Brief Description of the Drawings
