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…

Sonic Trampoline: How Audio Feedback Impacts the User’s Experience of Jumping

Posted on January 30, 2016 by Matlab-Projects |

To investigate how auditory augmentation influences user jumping activity on an elastic trampoline, the authors developed a system to interactively augment the trampoline’s sound. The system’s sound design is inspired…

Review paper on text and audio steganography using GA

Posted on January 30, 2016 by Matlab-Projects |

Steganography is used to hide the secret information within a cover media in such a way that the existence of the message could not be noticeable. Here we are considering audio file…

Auditory Distance Rendering Based on ICPD Control for Stereophonic 3D Audio System

Posted on January 30, 2016 by Matlab-Projects |

In this letter, we propose a new auditory distance rendering (ADR) algorithm based on the interchannel phase difference (ICPD) control. In the conventional ICPD control, distance perception of the sound…

Emotion recognition and emotion based classification of audio using genetic algorithm – an optimized approach

Posted on January 30, 2016 by Matlab-Projects |

Music information retrieval (MIR) is one of the vast areas of research and it is gaining more and more attention from researchers, as well as from the music developing community.…

A feature selection algorithm of music genre classification based on ReliefF and SFS

Posted on January 30, 2016 by Matlab-Projects |

The feature selection algorithm can select the optimal feature subset from lots of music features about music genre classification, removing the irrelevant and redundant features to reduce the number of…
