SoundShape – Headphone Transfer Function Database
Abstract
This article introduces the SoundShape database, which contains measured headphone transfer functions (HTFs). Details of the various stages of SoundShape’s implementation, including project assumptions, software used, and the measurement environment, are shown. The measurement process is explained. Moreover, the construction and processing of signal files within SoundShape are discussed. The AKtools script in MATLAB is employed to derive the HpTF functions. Analyses of selected audio signal samples from the database highlight similarities and differences among the three headphone models tested. The paper concludes with a summary of the results, including recommendations on how the database can be utilized. The presented SoundShape HpTF database is publicly available from https://doi.org/10.34808/4wya-z425.
