Open Source C++ Audio Analysis Software - Page 5

QTuneroid is an instrument tuner for linux, using Qt for its UI and ALSA for sound input. It is a fork of Tuneroid software for KDE, made because i cannot found good and recent tuner without KDE dependency.

QtOIDUA is a Qt-based graphical user interface for OIDUA, an Audiolist clone that catalogs audio files based on their location in a directory tree.

General C++ Library, with modules for Computer Vision, Pattern Recognition and much more.

RT Audio Processor is a free, cross platform, open-source, realtime audio processing library. The library exports a C++ API which is intended to offer flow-based programming framework for realtime audio processing.

Qt-based software for audio measurement (speaker parameters, frequency and phase response, etc).

Rhythm Feedback provides a visualization of played rhythms in realtime. The audio-input (mic) is used for the detection. Smooth tempo changes are tracked and displayed as a curve. Single notes are qualified as early, in-time or late.

The CPU RightMark suite is meant for objective measurement of performance of modern and future processors in different computational tasks such as numerical modeling of physical processes and solving of 3D graphic problems.

Spectral Orchestrator--A software tool for musicians and composers that creates harmonies/orchestrations from digitally recorded sound files. Currently compiles and runs in Linux and Mac OS X (and eventually Windows/Cygwin).

Automatic cutter and mp3 converter of captures from TV music channels

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

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

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

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.

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.

Speaker Workshop is an application for testing speaker drivers using a Windows sound card, then designing and simulating loudspeakers and enclosures and creating and optimizing crossovers.

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 tool for Native Instrument's Traktor which automates tagging WAV files purchased on popular dance music sites. Currently supported sites: www.trackitdown.net, Juno Download, and Beatport.

Timecode is a library for analysing timecode vinyls. After submitting samples, it returns commands like speed, direction and position for any media player which supports this library. It is written in operating system independent c++ code.

Catching a note by analyzing guitar sound. The final goal of this project is a program which draws a TAB automatically from guitar play.

The UIless Playlist Manager intends to be a generic music player, capable of managing multiple playlists based on different criterias, scalable to accomodate the needs of end users. UPM is an experiment in AI-using playlist management technology.

This project is a software oscilloscope for the Universal Software Radio Peripheral. It includes such features as maximum level triggers on any channel, a spectrum analyzer, and more.

Visore is a software project for the sound restoration of vinyl (gramophone) records. Visore filters the noise caused by scratches, dust and degradation and amplifies the sound where necessary.

VisualCube is a volumetric display out of 6*6*6 voxels, where each voxel get's represented by a 2-color LED. This project includes a bunch of tools used to control this peace of hardware, by taking advantage of the VisualCube library.

WMPBetterBars provides a set of interesting and accurate visualizations for Windows Media Player aimed at better representing the characteristics of the music more than simply being eye-candy.
