Measurement of individual Head Related Transfer Functions (HRTFs) can be inconvenient, expensive and time consuming. User selected HRTFs can alleviate the complexity of individually measured HRTFs and make better quality 3D audio available to more listeners. This paper presents the results of a study designed to investigate the use of user-selected HRTFs augmented with customized interaural cues. In the study presented, subjects were asked to select HRTFs that resulted in an accurate percept based on three specific criteria: externalization quality, elevation and front/back discrimination. Subjective tests were conducted using three stimuli: Infrapitch signal, Speech and Music. Results of the experiment are presented.
