146 <a class="el" href="classVamp_1_1Plugin.html" title="Vamp::Plugin is a base class for plugin instance classes that provide feature extraction...">Vamp::Plugin</a> is a base class for plugin instance classes that provide feature extraction from audio or related data.

148 In most cases, the input will be audio and the output will be a stream of derived data at a lower sampling resolution than the input.<p>
|
|
cannam@35
|
149 Note that this class inherits several abstract methods from <a class="el" href="classVamp_1_1PluginBase.html" title="A base class for plugins with optional configurable parameters, programs, etc.">PluginBase</a>. These must be implemented by the subclass.<p>

|
151 <a class="el" href="structVamp_1_1Plugin_1_1Feature.html">Feature</a> extraction plugins are managed differently from real-time plugins (such as VST effects). The main difference is that the parameters for a feature extraction plugin are configured before the plugin is used, and do not change during use.<p>
|
|
cannam@35
|
152 1. Host constructs the plugin, passing it the input sample rate. The plugin may do basic initialisation, but should not do anything computationally expensive at this point. You must make sure your plugin is cheap to construct, otherwise you'll seriously affect the startup performance of almost all hosts. If you have serious initialisation to do, the proper place is in <a class="el" href="classVamp_1_1Plugin.html#f26212cf5fc511b603a8b48034247822" title="Initialise a plugin to prepare it for use with the given number of input channels...">initialise()</a> (step 5).<p>
|
|
cannam@35
|
153 2. Host may query the plugin's available outputs.<p>
|
|
cannam@35
|
154 3. Host queries programs and parameter descriptors, and may set some or all of them. Parameters that are not explicitly set should take their default values as specified in the parameter descriptor. When a program is set, the parameter values may change and the host will re-query them to check.<p>
|
|
cannam@35
|
155 4. Host queries the preferred step size, block size and number of channels. These may all vary depending on the parameter values. (Note however that you cannot make the number of distinct outputs dependent on parameter values.)<p>
|
|
cannam@35
|
156 5. <a class="el" href="classVamp_1_1Plugin.html" title="Vamp::Plugin is a base class for plugin instance classes that provide feature extraction...">Plugin</a> is properly initialised with a call to initialise. This fixes the step size, block size, and number of channels, as well as all of the parameter and program settings. If the values passed in to initialise do not match the plugin's advertised preferred values from step 4, the plugin may refuse to initialise and return false (although if possible it should accept the new values). Any computationally expensive setup code should take place here.<p>
|
|
cannam@35
|
157 6. Host finally checks the number of values, resolution, extents etc per output (which may vary depending on the number of channels, step size and block size as well as the parameter values).<p>
|
|
cannam@35
|
158 7. Host will repeatedly call the process method to pass in blocks of input data. This method may return features extracted from that data (if the plugin is causal).<p>
|
|
cannam@35
|
159 8. Host will call getRemainingFeatures exactly once, after all the input data has been processed. This may return any non-causal or leftover features.<p>
|
|
cannam@35
|
160 9. At any point after initialise was called, the host may optionally call the reset method and restart processing. (This does not mean it can change the parameters, which are fixed from initialise until destruction.)<p>
|
|
cannam@35
|
161 A plugin does not need to handle the case where setParameter or selectProgram is called after initialise has been called. It's the host's responsibility not to do that. Similarly, the plugin may safely assume that initialise is called no more than once.

cannam@35

404 If this is FrequencyDomain, the host will carry out a windowed FFT of size equal to the negotiated block size on the data before passing the frequency bin data in to <a class="el" href="classVamp_1_1Plugin.html#e4aed3bebfe80a2e2fccd3d37af26996" title="Process a single block of input data.">process()</a>. The input data for the FFT will be rotated so as to place the origin in the centre of the block. The plugin does not get to choose the window type -- the host will either let the user do so, or will use a Hanning window.

458 A plugin may return 0 if it has no particular interest in the step size. In this case, the host should make the step size equal to the block size if the plugin is accepting input in the time domain. If the plugin is accepting input in the frequency domain, the host may use any step size. The final step size will be set in the <a class="el" href="classVamp_1_1Plugin.html#f26212cf5fc511b603a8b48034247822" title="Initialise a plugin to prepare it for use with the given number of input channels...">initialise()</a> call.

574 If the plugin's inputDomain is TimeDomain, inputBuffers will point to one array of floats per input channel, and each of these arrays will contain blockSize consecutive audio samples (the host will zero-pad as necessary).

575 If the plugin's inputDomain is FrequencyDomain, inputBuffers will point to one array of floats per input channel, and each of these arrays will contain blockSize/2+1 consecutive pairs of real and imaginary component floats corresponding to bins 0..(blockSize/2) of the FFT output. That is, bin 0 (the first pair of floats) contains the DC output, up to bin blockSize/2 which contains the Nyquist-frequency output. There will therefore be blockSize+2 floats per channel in total. The timestamp will be the real time in seconds of the centre of the FFT input window (i.e. the very first block passed to process might contain the FFT of half a block of zero samples and the first half-block of the actual data, with a timestamp of zero).<p>
