Auditory masking and MPEG-1 audio compression Abstract: In high-quality digital audio coding, a great deal of attention is focused on the auditory perception process, as the goal of audio compression is to attain perceptually-transparent compression and reproduction.

In this way, quantisation noise can be made almost inaudible at the receiver. In this paper, the psychoacoustic phenomenon of auditory masking is described. This is followed by a review of the MPEG-1 (Moving Pictures Experts Group) international standard for audio compression, including an outline of the psychoacoustic models used.

1.1 MPEG/audio Features and Applications MPEG/audio is a generic audio compression standard. Unlike vocal-tract-model coders specially tuned for speech signals, the MPEG/audio coder gets its compression without making assumptions about the nature of the audio source. Instead, the coder exploits the perceptual limitations of the human auditory system.

MPEG-I Audio Features PCM sampling rate of 32, 44.1, or 48 kHz Four channel modes: Monophonic and Dual-monophonic Stereo and Joint-stereo Three modes (layers in MPEG-I speak): Layer I: Computationally cheapest, bit rates > 128kbps Layer II: Bit rate ~ 128 kbps, used in VCD Layer III: Most complicated encoding/decoding, bit rates ~ 64kbps, originally intended …

An embedded audio coder (EAC) is proposed with compression performance rivals the best available non-scalable audio coder. The key technology that empowers the EAC with high performance is the implicit auditory masking. Unlike the common practice, where an auditory masking threshold is derived from the input audio signal, transmitted to the decoder and used …

INTRODUCTION The availability of high performance audio codec brings digital music into reality, and revolutionizes our audio experiences. The most popular audio compression technology today is probably MP3[4], which stands for layer III of …
