Description and detailed explanation on Fourier Transform, some FFT, LPC etc. Runable project demonstrates DCT transform on continuous audio, show and edit audio source with different zooming and view.

CoRoPa stands for Computational Rough Paths. The aim of CoRoPa is to provide a software framework for various ideas related to Rough Path Theory, including rough differential equations and the digital description of serial data streams.

C++ classes and function for signal synthesis and modification.

Yet Another Audio Feature Extractor is a toolbox for audio analysis. Easy to use and efficient at extracting a large number of audio features simultaneously. WAV and MP3 files supported, or embedding in C++, Python or Matlab applications.

CAMEL (Content-based Audio and Music Extraction Library) is an easy-to-use C++ framework developed for content-based audio and music analysis. The framework provides a set of tools for easy Segmentation, Feature Extraction, Domain Extraction, etc.

Easy-to-use platform-independent plugin API for the extraction of low-level features from audio data in PCM format, as required in the context of music information retrieval software.

A set of software components used to investigate and implement searching of music and audio. This covers content-based retrieval and meta-data based solutions, segmentation and content selection (summarisation) of audio and music (MIDI, MP3 and WAV).

Exscalibar is an EXtendable, SCalable Architecture for Live, Interactive or Batch-orientated Audio-signal Refinement.

iSense is an open source platform for real time video and audio signal processing for Mac OS X which features shared library filters and dynamic user definable scripting of application behavior.

FreeSP is an infrastructure for programming platform-independend online signal processing applications. Ports to specific platforms (like DSPs and microcontrollers) are made by simply exchanging the freeSP System-module.

Voice stress analysis tool. Sometimes used as an audio lie detector (ie. used for detecting stress in a person's voice to allow for the determination of truthfulness).

Ekstasis is currently a rapidly produced prototype version of a Digital Signal Processing (DSP) framework which seeks to provide signal/data processing modules which can be strung together via Boost library interprocess message queues. Tools for creating and destroying the communication queues, loading/saving PCM 44100 Hz to/from the signal processing chain, windowing the data (currently only a Hann windowing function module), performing a Discrete Fourier Transform (DFT) on the data (using...

Audio spectrum analyzer in software module and a hardware module to display the spectrum.
