Member Enumeration Documentation
| Enumerator | |
|---|---|
| OneSamplePerStep |
Results from each process() align with that call's block start. |
| FixedSampleRate |
Results are evenly spaced in time (sampleRate specified below) |
| VariableSampleRate |
Results are unevenly spaced and have individual timestamps. |

Member Data Documentation
| std::string Vamp::Plugin::OutputDescriptor::identifier |
The name of the output, in computer-usable form.
Should be reasonably short and without whitespace or punctuation, using the characters [a-zA-Z0-9_-] only. Example: "zero_crossing_count"

Referenced by FixedTempoEstimator::D::getOutputDescriptors(), AmplitudeFollower::getOutputDescriptors(), SpectralCentroid::getOutputDescriptors(), ZeroCrossing::getOutputDescriptors(), PowerSpectrum::getOutputDescriptors(), and PercussionOnsetDetector::getOutputDescriptors().
| std::string Vamp::Plugin::OutputDescriptor::name |
The human-readable name of the output.
Example: "Zero Crossing Counts"

Referenced by FixedTempoEstimator::D::getOutputDescriptors(), AmplitudeFollower::getOutputDescriptors(), SpectralCentroid::getOutputDescriptors(), ZeroCrossing::getOutputDescriptors(), PowerSpectrum::getOutputDescriptors(), and PercussionOnsetDetector::getOutputDescriptors().
| std::string Vamp::Plugin::OutputDescriptor::description |
A human-readable short text describing the output.
May be empty if the name has said it all already. Example: "The number of zero crossing points per processing block"

Referenced by FixedTempoEstimator::D::getOutputDescriptors(), AmplitudeFollower::getOutputDescriptors(), SpectralCentroid::getOutputDescriptors(), ZeroCrossing::getOutputDescriptors(), PowerSpectrum::getOutputDescriptors(), and PercussionOnsetDetector::getOutputDescriptors().
| std::string Vamp::Plugin::OutputDescriptor::unit |
The unit of the output, in human-readable form.

Referenced by FixedTempoEstimator::D::getOutputDescriptors(), AmplitudeFollower::getOutputDescriptors(), SpectralCentroid::getOutputDescriptors(), ZeroCrossing::getOutputDescriptors(), PowerSpectrum::getOutputDescriptors(), and PercussionOnsetDetector::getOutputDescriptors().
| bool Vamp::Plugin::OutputDescriptor::hasFixedBinCount |
True if the output has the same number of values per sample for every output sample.
Outputs for which this is false are unlikely to be very useful in a general-purpose host.
Definition at line 239 of file vamp-sdk/Plugin.h.
Referenced by FixedTempoEstimator::D::getOutputDescriptors(), AmplitudeFollower::getOutputDescriptors(), SpectralCentroid::getOutputDescriptors(), ZeroCrossing::getOutputDescriptors(), PowerSpectrum::getOutputDescriptors(), and PercussionOnsetDetector::getOutputDescriptors().
| size_t Vamp::Plugin::OutputDescriptor::binCount |
The number of values per result of the output.
Undefined if hasFixedBinCount is false. If this is zero, the output is point data (i.e. only the time of each output is of interest, the value list will be empty).

| std::vector<std::string> Vamp::Plugin::OutputDescriptor::binNames |
The (human-readable) names of each of the bins, if appropriate.
This is always optional.
Definition at line 253 of file vamp-sdk/Plugin.h.
| bool Vamp::Plugin::OutputDescriptor::hasKnownExtents |
True if the results in each output bin fall within a fixed numeric range (minimum and maximum values).
Undefined if binCount is zero.

Referenced by FixedTempoEstimator::D::getOutputDescriptors(), AmplitudeFollower::getOutputDescriptors(), SpectralCentroid::getOutputDescriptors(), ZeroCrossing::getOutputDescriptors(), PowerSpectrum::getOutputDescriptors(), and PercussionOnsetDetector::getOutputDescriptors().
| float Vamp::Plugin::OutputDescriptor::minValue |
Minimum value of the results in the output.
Undefined if hasKnownExtents is false or binCount is zero.
Definition at line 266 of file vamp-sdk/Plugin.h.
Referenced by FixedTempoEstimator::D::getOutputDescriptors().
| float Vamp::Plugin::OutputDescriptor::maxValue |
Maximum value of the results in the output.
Undefined if hasKnownExtents is false or binCount is zero.
Definition at line 272 of file vamp-sdk/Plugin.h.
Referenced by FixedTempoEstimator::D::getOutputDescriptors().
| bool Vamp::Plugin::OutputDescriptor::isQuantized |
True if the output values are quantized to a particular resolution.
Undefined if binCount is zero.
Definition at line 278 of file vamp-sdk/Plugin.h.
Referenced by FixedTempoEstimator::D::getOutputDescriptors(), AmplitudeFollower::getOutputDescriptors(), SpectralCentroid::getOutputDescriptors(), ZeroCrossing::getOutputDescriptors(), PowerSpectrum::getOutputDescriptors(), and PercussionOnsetDetector::getOutputDescriptors().
| float Vamp::Plugin::OutputDescriptor::quantizeStep |
Quantization resolution of the output values (e.g.
1.0 if they are all integers). Undefined if isQuantized is false or binCount is zero.
Definition at line 285 of file vamp-sdk/Plugin.h.
Referenced by FixedTempoEstimator::D::getOutputDescriptors(), ZeroCrossing::getOutputDescriptors(), and PercussionOnsetDetector::getOutputDescriptors().
| SampleType Vamp::Plugin::OutputDescriptor::sampleType |
Positioning in time of the output results.
Definition at line 302 of file vamp-sdk/Plugin.h.
Referenced by FixedTempoEstimator::D::getOutputDescriptors(), AmplitudeFollower::getOutputDescriptors(), SpectralCentroid::getOutputDescriptors(), ZeroCrossing::getOutputDescriptors(), PowerSpectrum::getOutputDescriptors(), and PercussionOnsetDetector::getOutputDescriptors().
| float Vamp::Plugin::OutputDescriptor::sampleRate |
Sample rate of the output results, as samples per second.
Undefined if sampleType is OneSamplePerStep.
If sampleType is VariableSampleRate and this value is non-zero, then it may be used to calculate a resolution for the output (i.e. the "duration" of each sample, in time, will be 1/sampleRate seconds). It's recommended to set this to zero if that behaviour is not desired.

| bool Vamp::Plugin::OutputDescriptor::hasDuration |
True if the returned results for this output are known to have a duration field.
