example Vamp plugins, host and RDF generator
DescriptionVamp 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.
Upload new screenshots
Thanks for uploading more screenshots. Please note:
- Your screenshot should contain a typical scene when working with it.
- Take only a screenshot of the respective application and not of your whole desktop (unless the screenshot is meant for a window manager).
- Your screenshots must be in PNG format.
- You can upload multiple images at once.
- Your screenshot need to be approved by the moderators first. You will already see your screenshot but it will not be visible to others instantly. If moderators reject your upload you will get notified next time you visit this site (requires cookies).
- Images larger than 800x600 pixels will automatically be reduced. So don't try to capture too much detail in a screenshot. It may become unreadable. Shrink the applications window if possible.
- Screenshots are made public and can freely be used by anyone.
- Useful programs for making screenshots are shutter, ksnapshot (KDE), gimp, xwd or scrot. See the Debian wiki for more information on how to make screenshots under Debian.
- Please set your language to english so that everybody understands it. If you don't use english by default please start your application from a shell using after setting "export LANG=C".
