Speech vs music discrimination using Empirical Mode Decomposition

Posted on February 2, 2016 by Matlab-Projects |

This work explores the use of Empirical Mode Decomposition (EMD) for discriminating speech regions from music in audio recordings. The different frequency scales or Intrinsic Mode Functions (IMFs) obtained from EMD of…

Sound source identification for scene analysis

Posted on February 2, 2016 by Matlab-Projects |

The ability to recognize objects and events by interpreting sound signals is one of the fundamental qualities of human. The ability to categorize objects and events using auditory signals is…

Electrical network signal’s waveform and frequency logging for forensic

Posted on February 2, 2016 by Matlab-Projects |

In this paper we develop a framework for collecting the ENF (electric network frequency) variations in a database, which can be used in digital media authentication and time stamping. The…

GPU implementation of an audio fingerprints similarity search algorithm

Posted on February 2, 2016 by Matlab-Projects |

This paper describes a parallel implementation of a promising similarity search algorithm for an audiofingerprinting system. Efficient parallel implementation on a GPU accelerates the search on a dataset containing over 61…

Voice Activity Detection (VAD) using Bipolar Pulse Active (BPA) features

Posted on February 2, 2016 by Matlab-Projects |

This paper introduces a new method of extracting features of a signal called Bipolar Pulse Active (BPA) features. The BPA extracts information from signals and decomposes them, using a series…

An imperceptible and robust audio steganography employing bit modification

Posted on February 2, 2016 by Matlab-Projects |

Modification of bit values of samples in accordance with data to be embedded in audio steganography can have high payload at low complexity. Index of the bit modified in the stego signal,…

Posted on February 2, 2016 by Matlab-Projects |

Recently, people have been interested in sharing what they are watching on TV, allowing the development of Social TV Applications often based on mobile devices. In this context, this paper…

Classification of normalized healty and pathological lung sounds

Posted on February 2, 2016 by Matlab-Projects |

In this paper, lung sounds were classified as healthy and pathological. Means and standard deviations of Mel Frequency Cepstrum Coefficients were used as features and also parameters obtained by exponential…

Gun type recognition from gunshot audio recordings

Posted on February 2, 2016 by Matlab-Projects |

This paper describes an extension of an intelligent acoustic event detection system, which is able to recognize sounds of dangerous events such as breaking glass or gunshot sounds in urban…

Fetal phonocardiogram extraction using single channel blind source separation

Posted on February 2, 2016 by Matlab-Projects |

Frequent and long-term monitoring of fetal health status is still a challenging task in high-risk pregnancies. This paper presents a fully noninvasive method to extract fetal heart sound (FHS) from…
