176 <div class="textblock"><p><a class="el" href="classVamp_1_1HostExt_1_1PluginChannelAdapter.html" title="PluginChannelAdapter is a Vamp plugin adapter that implements a policy for management of plugins that...">PluginChannelAdapter</a> is a <a class="el" href="namespaceVamp.html">Vamp</a> plugin adapter that implements a policy for management of plugins that expect a different number of input channels from the number actually available in the source audio data. </p>
177 <p>A host using <a class="el" href="classVamp_1_1HostExt_1_1PluginChannelAdapter.html" title="PluginChannelAdapter is a Vamp plugin adapter that implements a policy for management of plugins that...">PluginChannelAdapter</a> may ignore the getMinChannelCount and getMaxChannelCount reported by the plugin, and still expect the plugin to run.</p>
178 <p><a class="el" href="classVamp_1_1HostExt_1_1PluginChannelAdapter.html" title="PluginChannelAdapter is a Vamp plugin adapter that implements a policy for management of plugins that...">PluginChannelAdapter</a> implements the following policy:</p>
179 <ul>
180 <li>If the plugin supports the provided number of channels directly, <a class="el" href="classVamp_1_1HostExt_1_1PluginChannelAdapter.html" title="PluginChannelAdapter is a Vamp plugin adapter that implements a policy for management of plugins that...">PluginChannelAdapter</a> will just run the plugin as normal.</li>
181 </ul>
182 <ul>
183 <li>If the plugin only supports exactly one channel but more than one channel is provided, <a class="el" href="classVamp_1_1HostExt_1_1PluginChannelAdapter.html" title="PluginChannelAdapter is a Vamp plugin adapter that implements a policy for management of plugins that...">PluginChannelAdapter</a> will use the mean of the channels. This ensures that the resulting values remain within the same magnitude range as expected for mono data.</li>
184 </ul>
185 <ul>
186 <li>If the plugin requires more than one channel but exactly one is provided, the provided channel will be duplicated across all the plugin input channels.</li>
187 </ul>
188 <p>If none of the above apply:</p>
189 <ul>
190 <li>If the plugin requires more channels than are provided, the minimum acceptable number of channels will be produced by adding empty (zero valued) channels to those provided.</li>
191 </ul>
192 <ul>
193 <li>If the plugin requires fewer channels than are provided, the maximum acceptable number of channels will be produced by discarding the excess channels.</li>
194 </ul>
195 <p>Hosts requiring a different channel policy from the above will need to implement it themselves, instead of using <a class="el" href="classVamp_1_1HostExt_1_1PluginChannelAdapter.html" title="PluginChannelAdapter is a Vamp plugin adapter that implements a policy for management of plugins that...">PluginChannelAdapter</a>.</p>
196 <p>Note that <a class="el" href="classVamp_1_1HostExt_1_1PluginChannelAdapter.html" title="PluginChannelAdapter is a Vamp plugin adapter that implements a policy for management of plugins that...">PluginChannelAdapter</a> does not override the minimum and maximum channel counts returned by the wrapped plugin. The host will need to be aware that it is using a <a class="el" href="classVamp_1_1HostExt_1_1PluginChannelAdapter.html" title="PluginChannelAdapter is a Vamp plugin adapter that implements a policy for management of plugins that...">PluginChannelAdapter</a>, and be prepared to ignore these counts as necessary. (This contrasts with the approach used in <a class="el" href="classVamp_1_1HostExt_1_1PluginInputDomainAdapter.html" title="PluginInputDomainAdapter is a Vamp plugin adapter that converts time-domain input into frequency-doma...">PluginInputDomainAdapter</a>, which aims to make the host completely unaware of which underlying input domain is in fact in use.)</p>
197 <p>(The rationale for this is that a host may wish to use the <a class="el" href="classVamp_1_1HostExt_1_1PluginChannelAdapter.html" title="PluginChannelAdapter is a Vamp plugin adapter that implements a policy for management of plugins that...">PluginChannelAdapter</a> but still discriminate in some way on the basis of the number of channels actually supported. For example, a simple stereo audio host may prefer to reject plugins that require more than two channels on the grounds that doesn't actually understand what they are for, rather than allow the channel adapter to make a potentially meaningless channel conversion for them.)</p>
198 <p>In every respect other than its management of channels, the <a class="el" href="classVamp_1_1HostExt_1_1PluginChannelAdapter.html" title="PluginChannelAdapter is a Vamp plugin adapter that implements a policy for management of plugins that...">PluginChannelAdapter</a> behaves identically to the plugin that it wraps. The wrapped plugin will be deleted when the wrapper is deleted.</p>

406 <p>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>
407 <p>Return any features that have become available after this process call. (These do not necessarily have to fall within the process block, except for OneSamplePerStep outputs.) </p>

932 <p>This is useful in situations where a plugin is wrapped by multiple different wrappers (one inside another) and the host wants to call some wrapper-specific function on one of the layers without having to care about the order in which they are wrapped. For example, the plugin returned by <a class="el" href="classVamp_1_1HostExt_1_1PluginLoader.html#a964689eb9688cd7e58e8c82ebb0d305f" title="Load a Vamp plugin, given its identifying key.">PluginLoader::loadPlugin</a> may have more than one wrapper; if the host wanted to query or fine-tune some property of one of them, it would be hard to do so without knowing the order of the wrappers. This function therefore gives direct access to the wrapper of a particular type. </p>
