Abstract

The concept of masking in psychoacoustics has invaded the daily lives of almost every audio listener since the initial release of the MPEG-1 standard. With the ubiquity of the MP3, the consumption of perceptually coded audio is impossible to avoid. While many people understand the concept of perceptual coding, it can be diffi cult to visualize what is actually happening to the information in the audio files. PsychoMasker is an App that provides real-time visualization of the psychoacoustic principles used in MPEG encoding to anyone with an iPad. The PsychoMasker App shows the user how the encoding process affects any song in the user's iTunes library step-by-step.
