A real-time headphone compensation system for spatial audio is presented in this thesis. To achieve optimal spa- tial audio accuracy it is necessary to know the listener’s personal ear re- sponse. Ear response has previously been measured using complex setups that are impractical for regular con- sumer applications. So, The purpose of this project was to develop a simple compensation system using affordable components.
Based on results from the a small ear response study, a prototype system was developed. The hardware com- ponent of the system was based on a modified AIAIAI TMA-2 headphone, while the software component was di- vided into three subsystems imple- mented in Matlab Simulink. Prototype system evaluation showed promis- ing results, however, the convergence speed of the adaptive subsystems as well as the accuracy of the magnitude estimation in the peak EQ subsystem could be improved.
