Sampling

Yawi3D (Yet Another Wand for ImageJ 3D) is a software project for the implementation of tools uselful in the supervisioned sampling of tumoral masses in CT images. It enables and simplifies the selection of a tumoral region on each slice of a CT analysis, and computes the volume of the selected...

SoundPitch is a nice little tool for changing the tempo, pitch and sampling rate of a music file in realtime. Many musicans who want to learn a track uses theses features to slow down the playback of a song. Features: * plays all commonly used music formats like MP3, MP2, MP1, OGG, WAV, AIFF,...

The WAV audio recording applet SDK is designed to create the web audio recorder on the web site. It allows to record the audio in WAV format from the web site and upload audio file to the web server via HTTP.Also, it is possible to save recorded audio file on the client computer and open it from...

A Simulink model that generates and displays a simple cosine wave. The model computes the cosine function using the continuous phase method, which is based on Euler's formula for the complex exponential. The cosine generator is provided as a subsystem, which the user can copy-and-paste into other...

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself....
