System and method for adaptive sound playback during physical activities

The invention provides an audio system for adaptive audio playback during physical activities comprising: an audio player (2) having one or more audio sources (3, 4) and being configured to output an audio signal (AS) based on one or more source signals (S1, S2) provided by the one or more audio sources (3, 4); and a control device (5) configured to control one or more settings (VS, ES, SO, CS1, CS2) of the of the audio player (2), which affect the audio signal (AS); wherein the control device (5) comprises a user interface (8) configured to input user preferences (UP) for the one or more settings (VS, ES, SO, CS1, CS2) of the audio player (2); wherein the control device (5) comprises a processor (9) configured to correlate user preferences (UP) and values of one or more sensor signals (SE1, SE2) corresponding to a physical strain of a user of the audio system (1), further configured to store the user preferences (UP) and the correlated values of the one or more sensor signals (SE1, SE2) in a memory (10) of the control device (5) and further configured to control the one or more settings (VS, ES, SO, CS1, CS2) of the audio player (2) based on the one or more sensor signals (SE1, SE2) and based on the user preferences (UP) and the correlated values of the one or more sensor signals (SE1, SE2) stored in the memory (10).
