The SoX Resampler library
High quality, one-dimensional sample-rate conversion library
The SoX Resampler library `libsoxr' performs one-dimensional sample-rate conversion—it may be used, for example, to resample PCM-encoded audio. It aims to give fast and high quality results for any constant (rational or irrational) resampling ratio. Phase-response, preserved bandwidth, aliasing, and rejection level parameters are all configurable; alternatively, simple `preset' configurations may be selected. An experimental, variable-rate resampling mode of operation is also included. -

SpecAnaSyn
Spectral Analysis and Synthesis of Sounds
This project provides two binaries, mostly identical in features: a command line application (using libpopt for option parsing), and a graphical application (using libgtkmm (version 2) for the GUI and libao for sound playing). It uses spectral modelling techniques for parameterized sound analysis and synthesis. For the analysis phase an STFT is done (using libfftw for doing FFTs), and then harmonic/sinusoidal analysis. For the synthesis phase additive synthesis is used. Using libsndfile for... -

Continuous choice of string resonance at each point live music in CPU
Nonlinearly change frequencies and echos for live music by CPU. I found a way to normalize 1d wavefunction amplitude so this hack and its random heat vibrations are still unitary, even while microphone vibrating adds energy to part of 1d string of position and speed scalar arrays. The sparse part is, while the arrays are perfectly dense and linear, time is sparse when some springs vibrate with a larger multiplier of position subtracted from speed. In other words, this hack is a quanta level... -

SINE Isochronic Entrainer
Free and Open Source Brainwave Entrainment application
SINE Isochronic Entrainer is a Free and Open Source Brainwave Entrainment application for PC, Android, and HTML5. Brainwave Entrainment is the practice of using sounds, visual stimuli or even electromagnetic fields to alter the frequency of brainwaves. It can be done for several reasons: people with insomnia can take great benefit from it, but it can also be used to improve your attention span, and even simulate the effects of some recreational drugs. The effect is not permanent, and... -

Kangas Sound Editor
Synthesizer, mixing, sound effects, music composition and production.
This kangaroo-themed program allows the user to create their own music and sound effects, effectively from scratch. There are two variants of the program: Kangas Sound Editor which requires MySQL for its database, and Kangas Sound Editor QI which does not (it uses an internal database - HSQLDB - instead). Kangas Sound Editor (QI) uses a system of boxes or cells, which are placed by the user onto a timeline using drag-and-drop, and which represent entities such as chords, repetition,... -

ApplPi
A stochastic noise machine
ApplPi is a stochastic noise machine that creates a soothing background noise for those who can't work in complete silence or need to mask distracting noise. It creates sound similar to any noise machine, but it's more musical and harmonic. Additionally, you can control the frequency (note) of the sound and choose from built-in presets of noise/sound. -

Maestro Project
Maestro is a Rethought Virtual Metronome
Maestro is a free open source multiplatform virtual metronome, totally rethought to provide new functionalities to the user and a much better and easy-to-use interface. We know: there are lots of virtual metronomes, and many of them are also free software. However, there are no one like Maestro. Our professional team have produced a more ergonomic interface, powerfull but simple and easy. The inovative features were created in consonance with professional musicians and reflect their... -

pyscope
Software oscilloscope using Python and tkinter
Software oscilloscope using Python and tkinter. Supports multiple sources: socket, file, audio, USB. Displays data by samples, time or frequency. Scales the input automatically or manually. It has been renamed "pdatascope" to avoid a name-clash with Pyscope, a scoping package on PyPi. See https://sourceforge.net/p/pydatascope/ for the latest code. -

Minaton
Minaton is a fat sounding mono subtractive software synthesizer
This is my first music software synthesizer project, developed over the last two weeks it's now in a usable state but there are still things I wan't to do, In using floating point values for all parameters I tried to get away from the steppy digital sounds you often hear on software synthesizers, I've used real analogue synthesizers since the late 1980s so know how they should sound, deep, warm, fluid and rich. The synth has three oscillators, two LFOs, One low pass resonant filter,... -

Simple Stop-motion Time-lapse Toolkit
Short bash script to create Stop Motion and Time-Lapse videos
This is a simple but powerful bash script to create stop motion and time-lapse videos from an Internet URL or an attached video device (see examples). Simply point it at an image source, set the capture frequency, and starting recording stillframes. You can view your stillframes as a video, or convert to a true video format at any point. Bad frames can be browsed/removed with the operating system file browser. -
