Lossy audio compression transforms the signal into a frequency representation by employing psychoacoustic models which remove information from the signal that is not perceptible to human listeners (e.g., due to masking effects). Although lossy compression has different goals than feature extraction, features may benefit from the psychoacoustically preprocessed signal …

The Psychoacoustic Model. The branch of psychoacoustics examines the concept of auditory masking and its effect on compression. Within each subband where blurring occurs the presence of a strong tonal signal can mask a region of weaker signals. This …

In MPEG 1, psychoacoustic model plays a crucial role in audio compression. In audio compression technology, compression will be achieved by exploiting the auditory masking characteristic of human ear. By applying psychoacoustic principles, it is possible to analyze the signal and computation of noise. Here, signal masking is a function of frequency.
