The Auditory Pitch Tracking (APT) is a specialized Windows Presentation Foundation (WPF) application designed in C# to facilitate voice pitch task experiments in behavioral science research. Designed by the Biocomputing (Singh) lab and the Human Brain Research Lab, this software emphasizes precise, real-time pitch detection and tracking, offering researchers an intuitive and robust platform for exploring various aspects of pitch control. The APT features five unique voice pitch tasks, each tailored to assess specific dimensions of pitch behavior, such as sustainability, elevation, lowering, and continuous modulation. Researchers can present these tasks using two auditory target options: pre-recorded voice pitch targets or subject-generated targets. The latter utilizes the Audapter package to create customized voice pitch targets based on a 5-second sustained "ah" recording. Upon completing an experiment, APT generates a comprehensive output that includes the subject's detected pitch data, the generated pitch targets, a full session recording, and detailed time-stamped event logs. With support for a 48,000 Hz sampling rate, APT is optimized exclusively for Windows PCs, ensuring a seamless experience for researchers in behavioral science and auditory studies.
