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 …

Basic Audio Compression sound can be masked by other sounds and the resulting sound and Decompression Process cannot be detected by human ear. Because of this, psychoacoustic principles focus on removing the irrelevant sound and thus achieving compression.

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 …

Knowing how the hearing system interprets the sounds we make, we can creatively hijack that system by artifically recreating certain responses it has to particular audio phenomena. Here you’ll also gain some extra insights into how and why certain types of audio processing and effects are so useful, particularly EQ , compression and reverb ...

of psychoacoustic models. Audio compression methods try to represent the original audio with as low bit rate as possible. High audio quality is achieved by rendering quantization noise inaudible. The exploitation of psychoacoustic models in the design of audio coders has led to high compression
