Hearing aid algorithms

A method of operating an audio processing device for processing an electric input signal representing an audio signal and providing a processed electric output signal, the method comprising:

• receiving the electric input signal representing the audio signal;
• providing an event-control parameter indicative of changes related to the electric input signal and for controlling processing of the electric input signal;
• storing a representation of at least a part of the electric input signal;
• providing a processed electric output signal with a configurable delay based on the stored representation of the at least electric input signal or a part thereof and controlled by the event-control parameter, and
• playing the processed electric output signal back faster than it is recorded in order to catch up with the input signal.

An audio processing device, comprising

• a receiver for receiving an electric input signal representing an audio signal;
• a controller for generating an event-control signal;
• a memory for storing a representation of at least a part of the electric input signal;
• and
• a signal processing unit configured to provide a processed electric output signal based on the stored representation of the at least a part of the electric input signal with a configurable delay controlled by the event-control signal, wherein
• the audio processing device is configured to play the processed electric output signal back faster than it is recorded to catch up with the input signal.
