A software tool is presented for performing perceptual audio evaluation and psychoacoustic measurement, controlling the interaction with both the subject and the playback environment. For this purpose a repertoire of test procedures has been implemented, including popular qualitative and quantitative approaches. By using OpenSound Control commands, not only traditional multi-channel reproduction is supported, but also advanced spatial audio reproduction such as dynamic binaural synthesis or wavefield synthesis. WhisPER has been written in MATLAB to facilitate its further development within the scientific community. As opposed to existing libraries it provides a coherent graphical user interface system allowing easier access and configuration also for users without advanced programming experience.
