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. -

ISSE
An Interactive Source Separation Editor
In applications such as audio denoising, music transcription, music remixing, and audio-based forensics, it is desirable to decompose a single-channel recording into its respective sources. To perform such tasks, we present a new software tool to perform source separation by painting on time-frequency visualizations of sound. Initial results shows the software can achieve state-of-the-art separation results compared to prior work. -

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. -

CQT-FW
CQT-FW is an audio analisys tool for multiple pitch recognition
CQT-FW(Constant Q transform with Fixed length Window) is a time-frequency transform for multiple pitch recognition in audio signals(songs). The transform CQT(Constant Q Transform) provide analisys frequencies in a exponencial way, like music does, but it have problems with the time resolution. In CQT-FW we have the same frequency resolution as CQT, but with fixed length windows in time, what leads to a constant time resolution as well. -

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. -

Minaton
Minaton is a fat sounding mono subtractive software synthesizer
...The synth has three oscillators, two LFOs, One low pass resonant filter, oscillator sync, two ADSR envelopes which can be redirected to oscillator pitch. The mod wheel controls filter frequency. It uses jackmidi rather than alsa for good solid timing, future developments planned are a lv2 / ladspa plug in version, pitch wheel control to be added. Example sounds can be found on my blog, any suggestions and additions would be appreciated. -
