Abstract: Techniques for providing acoustic feedback are disclosed. Several audio clips (21-23) have a synchronized beat. A sensor signal (16) received from a sensor has a sensor signal range divided by first and second thresholds (11, 12) into at least three sensor signal sub-ranges (13-15). An audio signal is output in response to the received sensor signal (16), the output audio signal comprising one or more of the audio clips. If the received sensor signal (16) exceeds the first threshold (11), at least one (21) of the one or more audio clips is discontinued and/or at least one additional audio clip (22) of the audio clips is initiated in synchronization with the one or more audio clips (21). If the received sensor signal (16) falls below the second threshold (12), at least one (21) of the one or more audio clips is discontinued and/or at least one additional audio clip (23) of the audio clips is initiated in synchronization with the one or more audio clips (21).
