example Vamp plugins, host and RDF generator

Vamp is an audio processing plugin system for plugins that extract descriptive information from audio data - typically referred to as audio analysis plugins or audio feature extraction plugins. This package contains the following example plugins: * Zero Crossings calculates the positions and density of zero-crossing points in an audio waveform. * Spectral Centroid calculates the centre of gravity of the frequency domain representation of each block of audio. * Simple Power Spectrum calculates a power spectrum from the input audio. Actually, it doesn't do any work except calculating power from a cartesian complex FFT output. The work of calculating this frequency domain output is done for it by the host or host SDK; the plugin just needs to declare that it wants frequency domain input. This is the simplest of the example plugins. * Amplitude Follower is an implementation of SuperCollider's amplitude-follower algorithm as a simple Vamp plugin. * Simple Percussion Onset Detector: estimates the locations of percussive onsets using a simple method described in "Drum Source Separation using Percussive Feature Detection and Spectral Modulation" by Dan Barry, Derry Fitzgerald, Eugene Coyle and Bob Lawlor, ISSC 2005. * Simple Fixed Tempo Estimator: calculates a single beats-per-minute value which is an estimate of the tempo of a piece of music that is assumed to be of fixed tempo, using autocorrelation of a frequency domain energy rise metric. It has several outputs that return intermediate results used in the calculation, and may be a useful example of a plugin having several outputs with varying feature structures. Also included is a simple host that can enumerate plugins, list their features, and process an audio file as well as a utility to generate Vamp plugin RDF templates.

audio analysis and feature extraction plugins (SDK)

Vamp is an audio processing plugin system for plugins that extract descriptive information from audio data - typically referred to as audio analysis plugins or audio feature extraction plugins. Just like an audio effects plugin (such as a VST), a Vamp plugin is a binary module that can be loaded up by a host application and fed audio data. However, unlike an effects plugin, a Vamp plugin outputs not processed audio but some sort of symbolic information. Typical things that a Vamp plugin might calculate include the locations of moments such as note onset times, visual representations of the audio such as histograms, or curve data such as power or fundamental frequency. Hosts using Vamp plugins include Audacity and Sonic Visualiser. This package contains C and C++ header files for developing Vamp plugins and hosts as well as source code of example plugins and a simple host.
