This paper presents a novel approach to enhancing college popular music education by incorporating an elite teaching optimization algorithm into customized model. A key feature of the proposed model is utilization high-fidelity wideband audio coding algorithm, which employs time-frequency analysis module based on MDCT fast reduce storage requirements. The psychoacoustic takes advantage high fre...

Dereverberation is a growing area of research with many new algorithms appearing in the literature. However, there are still no unanimously accepted tools for evaluation of these algorithms. In this paper, we introduce the Multichannel Acoustic Reverberation Database at York (MARDY) containing real measured multichannel room impulse responses. We demonstrate its use for the evaluation of dereve...

Chord progressions are the building blocks from which tonal music is constructed. Inferring chord progressions is thus an essential step towards modeling long term dependencies in music. In this paper, a distributed representation for chords is designed such that Euclidean distances roughly correspond to psychoacoustic similarities. Graphical models observing chord progressions are then compare...

Acoustic signal representations used in current audio coding algorithms can be improved by the incorporation of biorthogonality into Malvar's Extended Lapped Transform (ELT). Biorthogonality allows more exibility in the design of the analysis and synthesis windows by increasing the number of degrees of freedom. This paper examines this increase for two special cases and demonstrates the importa...

A method to implement digital audio watermarking in the frequency domain is presented. The embedding is performed by using chaos based sequences to increase the signature hiding properties. The proposed scheme takes into account the MPEG psychoacoustic model I to improve the robustness against the MP3 compression. Some tests have been performed to verify the system robustness against the MP3 co...

The paper proposes a performance evaluation and comparison of recent ITU-T and ETSI voice activity detection algorithms. The comparison was made using both objective and psychoacoustic parameters, so as to have reliable judgements that were close to subjective ones. A highly varied speech database was also set up to evaluate the extent to which VADs depend on language, the signal to noise ratio...
