CbProcessingVisual
Visual using the java processing API
I was asked to upload this project and give a short description here: It's based on java processing api. Then i used some fft analyzer which should be obvious looking at the code. There is a option to generate the fft file. this must be done first. Then the fft file can be used to render a movie. Not sure how the options worked to make arealtime fft analysis and show the video in realtime (it does not peprfform goog because some expensive framebuffer operations there) Ah ja, the demo video includes some effects that are not included in the source. ... -

WaveShop
Fast, bit-perfect audio editor that doesn't modify samples needlessly
WaveShop is an audio editor for Windows XP/Vista/7/8. Unlike many similar apps, WaveShop is bit-perfect, meaning samples aren't altered unless they need to be. Editing a portion of an audio file only affects that portion; the rest of the file is untouched. Blocks of audio can be cut and pasted without changing their contents at all. This is especially useful for patching a finished master without corrupting its dither. -

CoGA
R package for differential co-expression analysis
CoGA (Co-expression Graph Analyzer) is an R package to identify differentially co-expressed gene sets between two phenotypes. The software infers gene regulatory networks from gene expression data, and compares structural properties of the inferred networks based on their spectrum distributions. It also compares the networks in terms of their gene centralities, clustering coefficients and shortest path lengths. -

Xtreme Media Player
Xtreme Media Player is a free cross-platform media player.
...It provides the user with a graphical interface for choosing music files and playlists - and includes support for many audio file formats including .spx, .snd, .aifc, .aif, .wav, .au, .flac, .mp1, .mp2, .mp3, .ogg, .aac, and .m4a. The code is very modular to allow the straightforward extraction of core modules (such as the audio engine, the FFT analysis, the playlist management module, and several visualizations) to use in other projects as external libraries. A key feature of XtremeMP is the capability to view visualizations (on-screen graphics controlled by the music’s audio). These can have scientific/technical purposes such as depicting some properties of the audio (such as the Oscilloscope, Spectrum, Stereogram, and Spectrogram visualizations). -

SpeedScope
Spectrum Analyzer Software
SpeedScope 2014 is developed for use with doppler microwave sensor or any other sensor (like ultrasound doppler probe) which requires some kind of FFT processing (actually we do not use FFT but for the sake of simplicity...). Data is collected via PC sound card interface so sensor output parameters need to satisfy sound card input requirements. This application is portable, it does not write anything to registry (or anywhere else). This app does not 'phone home' or collect any user... -
