This method, known as swept-sine, log-chirp, swept-tone, or sine sweep uses an increasing frequency sinusoid to stimulate an acoustic device under test. The response is processed to compress the response to an impulse response. This method is robust against noise, time variance, and weak... Platforms: Matlab

This simulator creates a source to microphone impulse response in complex room environments. It's based on the image method by Steven Boll'79. You may select frequency dependent wall coefficients and orientation dependent sources. Please refer to the tutorial.pdf file for more information. To... Platforms: Matlab

The sound denoising algorithm is based on the popular spectral subtraction technique. Based on the spectrum of the vuvuzela sound, this denoising technique simply computes an antenuation map in the time-frequency domain. Then, the audio signal is restored by computing the inverse STFT. See [1-3]... Platforms: Matlab

Psychoacoustic Software Suite (PSS) goal is to assess the resolution (that is the minimal difference between tones a listener can detect) of the auditory system along various acoustic parameters (e.g., intensity, frequency). This is a platform that will allow user to present listeners with a... Platforms: Matlab

We present some basic programs written for the MATLAB environment for the analysis of optical and acoustic data and for signal processing. These programs exploit novel concept derived from a theoretical physics approach. These programs can be easily customized by the expert user, but they... Platforms: Matlab

Winaudio10 contains two Simulink/RTW libraries for processing real-time audio on Intel/Win32 platforms. The first library is WinAudio, which provides support for SoundBlaster and .wav file I/O. The second library is Buffered DSP, which includes various frame-based DSP blocks, as well as... Platforms: Matlab

horn.m is the main program which designs exponential and catenoidal horns. The user inputs the cutoff frequency (Hz) and the throat radius in (meters).horn.m calculates the required length and shape constant of the horn to efficiently radiate at the cutoff frequency. It is assumed that the cutoff... Platforms: Matlab

These files provide a fast implementation of the image-source model (ISM) for the simulation of room impulse responses (RIRs) in small-room acoustics. This implementation produces RIRs that are virtually identical to those obtained with the standard ISM, but the simulations are up to two orders... Platforms: Matlab

Removing back ground noise added to speech is a fundamental problem in mobile devices such as cell phones. There are several well studied methods to suppress noise.In this Simulink model, I model and simulate noise suppression using spectral subtraction. To better understand this method, please...

This is a very minimal, acoustic, multidimensional FDTD simulation in under 25 lines of code. The FDTD calculations are actually performed using very few commands (the number of dimensions of your simulation +1). The source is a d-de?hard sourced-deOao Gaussian pulse and there are no boundary... Platforms: Matlab

Chromaphone combines acoustic resonators to create drums, percussion, string, and synth-like instruments. Membranes, bars, marimbas, plates, strings, and tubes form pairs that get sparked into life by a mallet and a flexible noise source. The resonators' material, tuning, and coupling parameters...

Organisms must be sufficiently separated to be resolved as individual targets for valid TS measurements to be obtained. Pulse duration (?Ya*z, s) and sound speed (c, m*s-1) affect the separation of echoes through the relationship: Equation 18 [18] where ???a* R is the range between two... Platforms: Mac

We are often interested in the TSuNZ and SvNZ levels at different depths. This program determines what those values are given the frequency of the acoustic unit, ambient temperature, and the TS value at 1 meter or the Sv value at 1 meter. Platforms: Mac

Java OceanAtlas (or simply JOA) is a software application for viewing and manipulating oceanographic profile data. JOA was designed primarily for oceanographic sections but is also useful for looking at data also in the latitude-longitude domain. Here's a brief list of what JOA can do: * Open a... Platforms: Mac

In the beginning, when the Iser created Adium, the sound was a formless void, and quacks echoed through the deep. Then MrRoboto said, "Let there be Tokyo Train Station." And actually, C Major and Electric Dream came first, but people totally freaked out over the Train Station. And they saw how... Platforms: Mac
