Chris@115	44 <h3>2015–09–09 — jVamp v1.3 released</h3>
Chris@115	45
Chris@115	46 <p>Announcing v1.3 of jVamp, a Java/JNI interface allowing the use of native-code Vamp plugins from host applications written in Java or other JVM languages.</p>
Chris@115	47
Chris@115	48 <p>This release simplifies the API, removing an unnecessary dispose() call and eliminating a class of native-heap memory leak.</p>
Chris@115	49

Chris@115	52 <h3>2015–09–09 — Vamp Test Plugin v1.1 released</h3>
Chris@115	53
Chris@115	54 <p>Version 1.1 of Vamp Test Plugin, the world's least interesting Vamp plugin, is now available.</p>
Chris@115	55
Chris@115	56 <p>Vamp Test Plugin is the equivalent of a TV test signal: it produces a set of very simple static outputs intended to help the authors of Vamp hosts check that they are handling plugin output sample types correctly. This release adds an output which is calculated from the input (to facilitate testing that input blocks are provided correctly) and a frequency-domain version of the same.</p>
Chris@115	57
Chris@115	58 <p>See <a href="https://code.soundsoftware.ac.uk/projects/vamp-test-plugin" class="bbc_link" target="_blank">https://code.soundsoftware.ac.uk/projects/vamp-test-plugin</a> for more information.</p>

Chris@115	62 <h3>2015–09–09 — Vamp Plugin Tester v1.1 released</h3>
Chris@115	63
Chris@115	64 <p>Version 1.1 of the Vamp plugin tester, a program that loads and tests Vamp plugins for various common failure cases, is now available.</p>
Chris@115	65
Chris@115	66 <p>Info and downloads:</p>
Chris@115	67
Chris@115	68 <blockquote><a href="https://code.soundsoftware.ac.uk/projects/vamp-plugin-tester" class="bbc_link" target="_blank">https://code.soundsoftware.ac.uk/projects/vamp-plugin-tester</a></blockquote>
Chris@115	69
Chris@115	70 <p>Change log:</p>
Chris@115	71
Chris@115	72 <blockquote><a href="https://code.soundsoftware.ac.uk/projects/vamp-plugin-tester/repository/entry/CHANGELOG" class="bbc_link" target="_blank">https://code.soundsoftware.ac.uk/projects/vamp-plugin-tester/repository/entry/CHANGELOG</a></blockquote>
Chris@115	73
Chris@115	74 <p>The tester can't check whether you're getting the right results, but it can help you write more resilient and better-behaved plugins. It's a really good idea to run the tester on any new plugin before you release it.</p>
Chris@115	75
Chris@115	76 <p>There is some documentation in the README file, but the short version is that you run it at a command prompt with the library name and plugin name, colon-separated, as an argument:</p>
Chris@115	77
Chris@115	78 <pre>$ ./vamp-plugin-tester vamp-example-plugins:spectralcentroid</pre>
Chris@115	79
Chris@115	80 <p>... and see what it has to say about your plugins.</p>
Chris@115	81
Chris@115	82 <p>If it crashes in the middle of one of its tests, that probably means that your plugin has crashed when faced with some unexpected input. Run it in a debugger, or a memory checking utility if you have one, to find out where.<br>

Chris@115	126
Chris@115	127 <p>Version 2.5 of the Vamp plugin SDK is now available.</p>
Chris@115	128
Chris@115	129 <p>Vamp is a plugin API for audio analysis and feature extraction plugins written in C or C++.  Its SDK features an easy-to-use set of C++ classes for plugin and host developers, a reference host implementation, example plugins, and documentation.  It is supported across Linux, OS/X, and Windows.</p>

Chris@115	140 <h3>2012–11–23 — jVamp: Vamp plugins in Java applications</h3>
Chris@115	141
Chris@115	142 <p>jVamp is a JNI (Java Native Interface) library that permits Java applications to load and use Vamp audio analysis plugins.</p>
Chris@115	143
Chris@115	144 <p>jVamp is intended for application developers who are interested in adding capabilities to Java applications or a Java environment; it's not currently something that an end-user would normally wish to install. But if you are working in Java, you might well find it interesting.</p>
Chris@115	145
Chris@115	146 <p>Note that jVamp is intended to be compatible with the Android NDK as well as desktop Java, though it hasn't been tested there (and existing binary distributions of plugins do not usually include ARM builds).</p>
Chris@115	147
Chris@115	148 <p>See <a href="http://code.soundsoftware.ac.uk/projects/jvamp" class="bbc_link" target="_blank">http://code.soundsoftware.ac.uk/projects/jvamp</a> for more information.</p>

Chris@115	151 <h3>2009–10–28 — VamPy: Vamp plugins in Python</h3>
Chris@115	152
Chris@115	153 <p>VamPy, a Python wrapper for the Vamp plugin API, is now available.</p>
Chris@115	154
Chris@115	155 <p>Using VamPy you can write audio analysis or visualisation plugins for use in Vamp hosts with a quick and dynamic environment that is somewhat like working in Matlab or other high-level modelling environments.  VamPy has full two-way support for NumPy, an efficient numerical library for Python, and for the dynamic typing of Python.</p>
Chris@115	156
Chris@115	157 <p>You can download VamPy from :<br><a href="http://www.vamp-plugins.org/vampy.html" class="bbc_link" target="_blank">http://www.vamp-plugins.org/vampy.html</a></p>

Chris@115	160 <h3>2009–10–02 — New tutorials about how to get your first plugin to compile</h3>
Chris@115	161
Chris@115	162 <p>There are two new tutorials now available on the (also new) wiki at this site, both entitled "From Method To Plugin" and describing how to get your code compiled and running as a Vamp plugin.  One tutorial covers OS/X, the other Windows.</p>
Chris@115	163
Chris@115	164 <p><ul class="bbc_list"><li>Using OS/X command-line tools: <a href="http://vamp-plugins.org/wiki/mtp1" class="bbc_link" target="_blank">http://vamp-plugins.org/wiki/mtp1</a></li><li>Using Visual C++ on Windows: <a href="http://vamp-plugins.org/wiki/mtp2" class="bbc_link" target="_blank">http://vamp-plugins.org/wiki/mtp2</a></li></ul><p>I hope these are helpful!  If you find any errors, please let me know (or create an account on the wiki and correct them!)</p>
Chris@115	165
Chris@115	166 <p>The wiki homepage is at <a href="http://vamp-plugins.org/wiki/" class="bbc_link" target="_blank">http://vamp-plugins.org/wiki/</a>, and we'd welcome any contributions that might be interesting to other users or developers of plugins.</p>

Chris@115	169 <h3>2008–12–12 — Vamp plugin SDK v2.0 now available</h3>
Chris@115	170
Chris@115	171 <p>Version 2.0 of the Vamp plugin SDK is now available.</p>
Chris@115	172
Chris@115	173 <p>Vamp is a plugin API for audio analysis and feature extraction plugins written in C or C++. Its SDK features an easy-to-use set of C++ classes for plugin and host developers, a reference host implementation, example plugins, and documentation. It is supported across Linux, OS/X and Windows.</p>
Chris@115	174
Chris@115	175 <p>A documentation guide to writing plugins using the Vamp SDK can be found at <a href="http://www.vamp-plugins.org/guide.pdf">http://www.vamp-plugins.org/guide.pdf</a>.</p>
Chris@115	176
Chris@115	177 <h5>What's new in 2.0?</h5>
Chris@115	178
Chris@115	179 <ul>
Chris@115	180 <li>Each returned feature can now specify a proper duration as well as start time, value array, and label.</li>
Chris@115	181 <li>A new PluginSummarisingAdapter is provided in the host SDK, permitting hosts to easily obtain summary results such as averages based on a plugin's returned features.</li>
Chris@115	182 <li>An RDF ontology is provided for the description of Vamp plugin capabilities and configurations (see <a href="http://omras2.org/VampOntology">http://omras2.org/VampOntology</a>).</li>
Chris@115	183 <li>The SDK libraries have been reorganised so as to draw a clearer distinction between plugin and host SDKs.</li>
Chris@115	184 <li>Better platform-specific build documentation is provided (in the build directory), particularly for MSVC builds which now also feature project files for the example plugins.</li>
Chris@115	185 <li>Two new example plugins have been added (Simple Power Spectrum and Fixed Tempo Estimator).</li>
Chris@115	186 <li>The command-line host provided now has an extra-informative plugin information listing option (<code>--list-full</code>).</li>
Chris@115	187 </ul>
Chris@115	188
Chris@115	189 <h5>Backward compatibility</h5>
Chris@115	190
Chris@115	191 <p>A detailed compatibility statement is included in the SDK, but to summarise:</p>
Chris@115	192
Chris@115	193 <ul><li>Plugins and hosts built with 1.x and 2.0 SDKs are mutually compatible. You can load old plugins in new hosts and new plugins in old hosts.</li>
Chris@115	194 <li>Plugins written for 1.x can be compiled against 2.0 without modification.</li>
Chris@115	195 <li>Hosts written for 1.x will require some changes to #include directives, but most hosts should compile against 2.0 without other modifications.</li>
Chris@115	196 <li>Although the plugin binary interface is compatible with 1.x, the SDK libraries are not binary compatible with the 1.x libraries. Plugins and host code will need to be recompiled if they are to be updated to 2.0, not just re-linked.</li>
Chris@115	197 </ul>
Chris@115	198
Chris@115	199 <a name="20080709"></a>
Chris@115	200 <h3>2008–07–09 — Vamp plugin SDK v1.3 now available</h3>

Chris@115	203
Chris@115	204 <p>Vamp is a plugin API for audio analysis and feature extraction plugins written in C or C++.  Its SDK features an easy-to-use set of C++ classes for plugin and host developers, a reference host implementation, example plugins, and documentation.  It is supported across Linux, OS/X and Windows.</p>
Chris@115	205
Chris@115	206 <p>Version 1.3 is a maintenance release, with several bugfixes (almost all of which only affect hosts, not plugins) and no new features.</p>
Chris@115	207
Chris@115	208 <p>Changes since 1.2:</p>
Chris@115	209
Chris@115	210 <ul class="bbc_list"><li> PluginBufferingAdapter has several important fixes to bugs that could cause incorrect timings or output descriptors to be returned</li><li> Conversion between real-time and frames has been improved to avoid rounding error in round-trip calculations</li><li> Plugin lookup no longer relies on non-portable DT_REG</li><li> The SDK now compiles with gcc 4.3</li></ul><p>Plugins and hosts remain binary compatible with those built using the 1.0 version of the SDK.</p>

Chris@115	213 <h3>2008–03–05 — New developer documentation available</h3>
Chris@115	214
Chris@115	215 <p>A new guide to writing Vamp plugins in C++ is now up on the website.
Chris@115	216 You can get to it from the developer documentation page:</p>

Chris@115	223
Chris@115	224 <p>No big claims for how well organised, written, or (especially!) illustrated it is, but there is a decent amount of information in it and it's likely to be mostly right.</p>
Chris@115	225
Chris@115	226 <p>There is also a recent introductory presentation available here:</p>

Chris@115	232
Chris@115	233 <p>Version 1.2 of the Vamp plugin SDK is now available.</p>
Chris@115	234
Chris@115	235 <p>Vamp is a plugin API for audio analysis and feature extraction plugins written in C or C++.  Its SDK features an easy-to-use set of C++ classes for plugin and host developers, a reference host implementation, example plugins, and documentation.  It is supported across Linux, OS/X and Windows.</p>
Chris@115	236
Chris@115	237 <p>Version 1.2 contains a further addition to the host extension classes introduced in 1.1: a buffering adapter that hosts may use to avoid having to negotiate the plugin's preferred input step and block sizes.  This release also includes a Visual C++ project file as well as Makefiles tailored to Linux and OS/X.</p>
Chris@115	238
Chris@115	239 <p>Plugins and hosts remain 100% binary compatible with those built using the 1.0 version of the SDK.</p>

Chris@115	249
Chris@115	250 <p>The prior version 1.1 of the SDK introduced a new set of classes designed to make it very simple for an application to use Vamp plugins, without needing to do complicated plugin lookup or audio processing themselves.</p>
Chris@115	251
Chris@115	252 <p>Plugins and hosts remain 100% binary compatible with those built using the 1.0 version of the SDK.</p>
