Parameters and Inputs

(1/1)

Nordhal:
Hello,
I have a question concerning the parameters , and inputs for a vamp plugin.
Can we have parameters which are not numeric values?
For example, if I want to analyze audio source using a configuration file, will it be possible to add this file, or the name of the file , as a Vamp plugin parameter?

Thanks in advance

No, I'm afraid there is no support for this at all in Vamp as it currently stands.

One possible workaround for some situations may be for the plugin to scan a location in which configuration files are to be stored (e.g. a special directory) and then offer the configuration files found in there as named programs using the getPrograms/getCurrentProgram/selectProgram mechanism in PluginBase.

Nordhal:
This is a great idea to use the Program mechanism of a Vamp plugin. It could be a way for retrieving some input files.

Thank you for you answer,

I have another question.

My project is to align a score with audio performance, using the match vamp plugin.
A score would be related to another audio , let's call this the reference audio.

So the process should be :
- Import audio file (artist performance)
- use the plugin
- set the parameters : Score, and audio reference if exists
- align the performance  and the audio reference.

Can I, during the initialization step (from my vamp plugin) , influence the behavior of the vamp host? For example, after retrieving the audio reference, can I set up a new channel for this file, and begin the alignment? If not, is there a possibility to use two different audio files at the same time, just using a vamp plugin?
