Vamp plugins are almost by definition not real-time safe (strictly speaking there’s no reason an actual plugin can’t be, but it’s seldom practical for significant plugins and in any case the C++ wrapper in the SDK is not RT safe) and SV expects to operate on audio file data. What’s much less likely to happen in the near future is real-time analysis or recording. Sonic Visualiser will probably get JACK transport support pretty soon – it would be a handy feature generally. Vamp has documentation and a C++ SDK, and I’d be happy to help out in any way if you’re interested in using it. colours or curves based on timbral content), key estimation, etc. Natural applications for Vamp plugins in Ardour would include things like beat and onset detection, audio-to-MIDI, alternatives to waveforms for visualisation (e.g. (Sonic Visualiser’s own spectrogram view does not use a plugin.) It is possible to write a spectrogram Vamp plugin (you can get one from the Mazurka project), but it isn’t terribly efficient. note onset points, pitch tracking curves, tonal histograms). a high-resolution spectrogram) from audio, but more appropriate to lower volume slightly structured data (e.g. Vamp is not a format for “visualisation plugins”, in the sense that the plugins themselves don’t get to draw anything – they just return data that the host determines how to display.Īlso, the format is aimed at analysis more than visualisation in the sense that it’s far from optimal for extracting large quantities of data (e.g. two or three dimensional irregularly sampled floating point data. The outputs can be moderately complex, e.g. Vamp is an API for non-realtime plugins in C or C++ that take audio as input and return something other than audio as output. It’s not 'bout recording … It’s 'bout freezing time … Why reinvent the wheel, do you think is there someway to embed this as the “Analize” function in ardour2? perhaps another Idea would be to add support for VAMP plugins for waveform views and analysis views, it just have to be seen how is their performance.Īn idea I saw in this visualizer that shouldn’be that difficult to add in ardour is the possibility of annotate the waveforms … I mean metadata as you’re editing is not that bad, isn’t it? doesn’t the WAVE format support this in a kind of metadata chunk? ![]() This has the greatest FFT views I’ve ever seen and also a plugin architecture for Visualizing plugins (VAMP), and there are a bunch of ready-to-go visualizing plugins already, spectral views, note name views, etc. In no event shall the author be liable for any direct, indirect, incidental, special, exemplary, or consequential damages (including, but not limited to, procurement of substitute goods or services loss of use, data, or profits or business interruption) however caused and on any theory of liability, whether in contract, strict liability, or tort (including negligence or otherwise) arising in any way out of the use of this software, even if advised of the possibility of such damage.I’ve just got to finally compile Ardour2 on my gentoo (for Gentoo users a Hint: emerge dev-libs/glib-2.10.3, get also the pro-audio layman repository, easy as a cake) and tried the FFT view, nonethless is a work in progress it seems quite useful to me … anyway, as the developer wanted ideas … well, there’s this guy who has wrote the greatest analysis program I’ve ever seen: This software is provided by the author ''as is'' and any express or implied warranties, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose are disclaimed.
