Noisy

Do you miss the days of typewriters, when you heard a distinctive sound each time you pressed one of the keys? Those days are back when you use Noisy Keyboard. This free system tray-based utility lets you hear seven different types of sounds as you hunt and peck your way through another computing...

Calculates the average log-spectral distance between CLEAN and NOISY signals. It has the capability of calculating this distance for a specified sub-band as well. This measure is used for evaluation of processed speech quality in comparison to the original speech.

Spectral Subtraction method proposed by berouti for enhancement of noisy speech signals.


Platforms: Matlab

Calculates the average log-spectral distance between CLEAN and NOISY signals. Has the option of calculating this distance for speech active periods only. Also you can select a frequency range to study the distance in a sub-band.

This function quickly finds local peaks or valleys (local extrema) in a noisy vector using a user defined magnitude threshold to determine if each peak is significantly larger (or smaller) than the data around it. The problem with the strictly derivative based peak finding algorithms is that if...

This landmark-based audio fingerprinting system is able to match short, noisy snippets to a reference database in near-constant time.This is my implementation of the music audio matching algorithm developed by Avery Wang for the Shazam service. Shazam can identify apparently any commercial music...

How to fit a 2D Gaussian function to noisy data in Matlab? Or data with another number of dimensions and arbitrary fit function?It took me a while to find out how Matlab does this by the functions lsqcurvefit, fmincon or fminsearch. This project demonstrates how to use these functions to fit ND...

The extended Kalman filter can not only estimate states of nonlinear dynamic systems from noisy measurements but also can be used to estimate parameters of a nonlinear system. A direct application of parameter estimation is to train artificial neural networks. This function and an embeded example...

cdspeed is an application that can decrease the speed of you cdrom. Modern cdrom drives are too fast. It can take several seconds on a 60x speed cdrom drive to spin it up and read data from the drive. The result is that these drives are just a lot slower than a 8x or 24x drive. This is especially...
