How To Fix vamp-rdf-template-generator: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu vamp-rdf-template-generator is provided by vamp-examples package.

vamp-examples is:

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.

To fix this problem, we can install more using the command below.

sudo apt-get -y install vamp-examples

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install vamp-examples.

sudo apt -y install vamp-examples

Or if you have aptitude installed you can use the following command.

sudo aptitude install vamp-examples
