Spectrometer software for school use. Application reads from "web camera" as input spectrograph patteren.

Visualization plugin for XMMS, the X Multimedia System. Plugin uses OpenGL for rendering and scripts to define visualization types you want.

Scratchlib is a platform independent C++ library to detect the position, speed and direction of the timecode records "Stanton Final Scratch" and "Mixvibes v1"

Sculptor is a phase-vocoder-based package with real-time capabilites. You can use it to fiddle with soundfiles in the frequency domain, changing pitch and duration independently.

Guitar Effect Pedal on PandaBoard and/or BeagleBoard, the Gui is SDL

Segfried is an audio feature extraction and segmentation utility

SetFon focus is an interface web based for Praat resources (www.praat.org) wich focus speech sound annalysis; it is a gerent program for acoustic analysis PHP/Mysql based. Developed with the framework SIMP.

A general tool for creating and processing sound in a general manner. The plug-in system makes it possible to create a complete software studio with all kinds of cool little boxes.

Simpl is an open source library for sinusoidal modelling written in the Python programming language and making use of SciPy.

The Simple Network Enhanced Zulu-time Device (SNEZ-D) or Aftermarket CHU Decoder (A-CHU) is a complete radio-to-interface time reference in-a-box with software that decodes the CHU radio signal, and can be interfaced to NTP servers.

A simple playlist generator made primarily with portable mp3 devices in mind. Will support a custom path to be used in the playlist, to ensure that the playlist actually works with all types of devices. Will only support m3u for now, but probably other f

Software provides two features, 1. To identify the musical notes in a given audio file which the singer is singing at. 2. To let a user practice singing individual notes of Indian music, with graphical representation of his performance.

Sonogram and waveform display programm for Unix using different algorithms like FFT and LPC to display musical features or potential artefacts that you may no be able to hear. Superimposed tuneable Staff-Lines allow for easy transcription of music.

Sonic Flow are C/C++ libraries for dataflow-oriented audio signal processing. Advanced features: feedback, multirate and hierarchical networks; signal processing block library. High-quality chorus/flanger, compressor/expander, param.EQ etc. example code.

Sound Orgy is a suite of command line tools for the purpose of sound production and modification as well other misc sound related functons. Sound Orgy consists of components which use command line piping to connect to each other much like patch cords.

A set of Qt/C++ classes enabling cross-platform sound recording and pitch recognition. Can be used in software (e.g. instrument tuners, sound dictation, music teaching and tests) as a user input method. Includes a guitar-tuner example.

Real-time audio feature extraction and similarity matching in C++. PD and Max/MSP support via FLEXT.

A visualization of the fourier transform applied to sound data. Analyzes a time-domain sound sample using the Fourier Transform, and graphically displays the results and sound in real time. Attempts to audio into sheet music.

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 sound loading and saving allows to support many uncompressed sound file formats (WAV, AIFF, AU, headerless RAW, ...), and also OGG and FLAC, but MP3 isn't supported. Available parameters include window type, size, and overlapping; sinusoid discarding; equalization; time strechting, frequency scaling and shifting; frequency and amplitude interpolation; normalization; dynamic range compression and expansion, etc. It can be used to obtain new sounds, from existing sound files.

A simple Java GUI tool for looking at the Spectrum and Cepstrum of a sound clip.

Speech Made Visible is an experiment in showing some of the qualities of speech in printed text. Analyze a recording for attributes like pitch, intensity (loudness), and speed; then style the words in a transcript to suggest those characteristics.

The concept of Computer Aided Music Composition emerged as a natural sequel to the music hardware/software revolution dating back to early 50s. STOCASTICVS aims to grow into the best CAMC software yet, truly unleashing individual’s creative potential.

This software generates a distorted version of an audio file that can give a required audio quality. This is for use with subjective tests, such as MUSHRA, where an anchor is required of a particular quality.

SuperWillow is a Music Generation program. Artists have many influences which they have accumulated over the years by listening to countless pieces of music, this principle is reflected in SuperWillow.
