Copy-move detection of audio recording with pitch similarity

Posted on January 30, 2016 by Matlab-Projects |

The widespread availability of audio editing software has made it very easy to create forgeries without perceptual trace. Copy-move is one of popular audio forgeries. It is very important to identify audiorecording with duplicated segments.…

TCD-TIMIT: An Audio-Visual Corpus of Continuous Speech

Posted on January 30, 2016 by Matlab-Projects |

Automatic audio-visual speech recognition currently lags behind its audio-only counterpart in terms of major progress. One of the reasons commonly cited by researchers is the scarcity of suitable research corpora. This paper…

Multiple constant multiplication implementations in near-threshold computing systems

Posted on January 30, 2016 by Matlab-Projects |

Modern applications, such as video and audio processing, employ many licnear transforms and filters, such as the discrete cosine transform (DCT) and fast Fourier transform (FFT). There is a need to drastically…

Foreground suppression for capturing and reproduction of crowded acoustic environments

Posted on January 30, 2016 by Matlab-Projects |

Traditionally, sensor arrays and spatial filtering aim to enhance individual sources by suppressing ambient noise and reverberation. In this paper, the exactly opposite problem is examined, that of suppressing individual…

Multichannel Wiener filtering via multichannel decorrelation

Posted on January 30, 2016 by Matlab-Projects |

Extracting a target source signal from multiple noisy observations is an essential task in many applications of signal processing such as digital communications or speech and audio processing. The multi-channel Wiener filter is able…

On the Modeling of Rectangular Geometries in Room Acoustic Simulations

Posted on January 30, 2016 by Matlab-Projects |

This paper is concerned with an acoustical phenomenon called sweeping echo, which manifests itself in a room impulse response as a distinctive, continuous pitch increase. In this paper, it is…

Latency and cost requirements of systems for teaching MAC protocols

Posted on January 30, 2016 by Matlab-Projects |

Over the past decade, the physical (PHY) layer of communication systems has evolved with the addition of techniques such as orthogonal frequency division multiplexing (OFDM) and multi-carrier aggregation. This has…

Audio Watermarking Based on Fibonacci Numbers

Posted on January 30, 2016 by Matlab-Projects |

This paper presents a novel high-capacity audio watermarking system to embed data and extract them in a bit-exact manner by changing some of the magnitudes of the FFT spectrum. The key idea…

Detection and Classification of OFDM Waveforms Using Cepstral Analysis

Posted on January 30, 2016 by Matlab-Projects |

Cepstral analysis has been widely used in audio and speech processing applications because of its ability to reveal periodicities in a signal. The presence of cyclic prefix (CP) in orthogonal frequency division multiplexing (OFDM)…

An Efficient Cascaded Filtering Retrieval Method for Big Audio Data

Posted on January 30, 2016 by Matlab-Projects |

Fast audio retrieval is crucial for many important applications and yet demanding due to the high dimension nature and increasingly larger volume of audios in the internet. Although audio fingerprinting can greatly reduce its dimension while…
