Application of a Physiological Ear Model to Irrelevance Reduction in Audio Coding
نویسنده
چکیده
A previously published physiological ear model is applied as perceptual model to an audio coder complying with the ISO/ MPEG-2 AAC standard. The achieved subjective sound quality is compared to results from an optimized psychoacoustical model. Significant deviations of the generated masked thresholds from the physiological ear model and the psychoacoustical model are evaluated with respect to psychoacoustical measurements.

Perceptual audio coding using adaptive pre- and post-filters and lossless compression
This paper proposes a versatile perceptual audio coding method that achieves high compression ratios and is capable of low encoding/decoding delay. It accommodates a variety of source signals (including both music and speech) with different sampling rates. It is based on separating irrelevance and redundancy reductions into independent functional units. This contrasts traditional audio coding w...

Recently, automatic affective state recognition has been noteworthy for improving Human Computer Interaction (HCI), clinical researches and other various applications. Little attention has been paid so far to physiological signals for affective state recognition compared to audio-visual methods. Different affective states stimulate the Autonomic Nervous System (ANS) and lead to changes in physi...

In order to investigate the effect of salicylic acid and humic acid to mitigate the impact of drought tension during pollination of forage maize, the present experiment was conducted as split plots based on randomized complete blocks design with three replications at Isfahan University of Technology. Drought tension levels included: without tension (control), mild tension (75 percent crop capa...
متن کامل"Sparsification" of Audio Signals Using the MDCT/IntMDCT and a Psychoacoustic Model - Application to Informed Audio Source Separation
Sparse representations have proved a very useful tool in a variety of domain, e.g. speech/music source separation. As strictly sparse representations (in the sense of l) are often impossible to achieve, other ways of studying signals sparsity have been proposed. In this paper, we revisit the irrelevance filtering analysis-synthesis approach proposed in (Balazs et al., IEEE Trans. ASLP, 18(1), 2...
