Conventional channel-based room equalisation can reduce overall colouration caused by the response, however it cannot separately correct late and early parts of or consider reverberance in source signal. A compensation method is developed here for a signal which dry sound associated target reverberant response are encoded separately, possible an object-based audio framework. The modified using ...

Bark-scale warped linear prediction [WLP] is a very potential core for a monophonic perceptual audio codec [2]. In the current paper the WLP scheme is extended for processing complex valued signals (CWLP). Three di erent methods of converting a stereo signal to one complex valued signal are introduced. The philosophy behind the coding scheme is to integrate some aspects of modern wideband audio...

Homomorphic signal processing techniques are used to place information imperceivably into audio data streams by the introduction of synthetic resonances in the form of closely spaced echoes These echoes can be used to place digital identi cation tags directly into an audio signal with minimal objectionable degradation of the original signal

In this paper, we present the study of audio signal denoising, recognizing its audio type and retrieving similar signals from the database. Primarily the signal is denoised to remove any noise present in the unknown signal. Time Frequency Block Thresholding is used to achieve this. Removing the noise from audio signals requires processing of time-frequency coefficients in order to keep away fro...

This paper describes an application specific signal processor (ASSP) designed for miniature, ultra low-power, audio signal processing applications. The ASSP includes a high-fidelity weighted overlap-add (WOLA) filterbank, a 16-bit DSP core, two 14-bit A/D converters, a 14-bit D/A converter and a flexible set of peripherals. This design excels in applications that require efficient frequency-dom...

The internet Audio Rendering System (iARS) is an Internet browser extension extending the browser’s capabilities with real-time signal processing. The proposed system allows to receive audio streams from the Internet and apply various audio algorithms with no additional computational power needed from the server. iARS is part of the Internet Archive of Electronic Music (IAEM) project which is a...

AbstractIn this research paper a new audio watermarking scheme is proposed using Arnold transformation with DCT-DWT. In audio watermarking embedding firstly, the audio convert signal was divided evenly, the audio segments were selected from the divided audio, then by doing the DWT and DCT embedded the watermark to the low frequency coefficients of those audio segments which were selected. Water...

The current generation of mobile devices is capable of producing polyphonic sounds, has enough processing power for real-time signal processing, and much better sound quality than their predecessors. The importance of audio is increasing as we are moving towards multimodal user interfaces where audio is one of the major components. In this paper, we present new ways of using audio feedback more...

This paper proposes an audio signal segmentation and classification method using fuzzy c-means clustering. Recently, high performance of the audio signal segmentation and classification is required for audio-visual indexing because of the popular use of the Internet, higher bandwidth access to the network, widespread of digital recording and storage; and several methods have been proposed. They...
