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 …

Human Audio Perception: Masking The human auditory system has, as mentioned in the introduction, some interesting properties, which are exploited in perceptual audio coding. We have a dynamic frequency range from about 20 to 20000 Hz, and we hear sounds with intensity varying over many magnitudes. The hearing system may thus seem

©Yao Wang, 2004 EE3414: Audio Coding 18 Basic Steps in MPEG-1 Audio Coding 1. Use convolution filters to divide the audio signal into 32 frequency subbands --> sub-band filtering. 2. Determine amount of masking for each band based on its frequency (threshold-in-quiet), and the energy of its neighboring band in frequency and time

sound (masker) elevates the threshold (changes the audibility or sensitivity) of another sound (target). The hearing threshold in the presence of a masking signal is called the masked threshold. The masked threshold is the threshold intensity, IT, of a target signal at frequency, fT, in the presence of a masking stimulus with the intensity, IM. When the masker intensity is

MPEG-2 Advanced Audio Coding (AAC) ([4], see the description in [5]). AAC is a second-generation audio coding scheme for generic coding of stereo and multi-channel signals. Figure 3 shows a generic block diagram of a typical AAC encoder. Comparing this to Layer-3, the most visible difference is the addition of a number of new blocks.
