Units in Audio Plugin Interface

1 view (last 30 days)
Is there any way to set up the decimal precision to be shown in a audio plugin interface? Eg I don´t want the value of a parameter displayed as 3.7277 dB but 3.7 dB.

If you do a classdef yourself like is shown in https://www.mathworks.com/help/audio/ref/audioplugininterface.html#d117e26333 then you can define your own display() method for that class.

When I use the example at https://www.mathworks.com/help/audio/ug/plugin-gui-design.html then the relevant portion appears to be the call to parameterTuner . That in turn is a method inside ParameterTunable.m . The important step that takes a built-up description of an interface and builds the interface, is createParameterTuningController . Unfortunately that is a .p file. The operation of the interface is hidden inside .p files, so I do not know how to change the behavior.
You will need to open a technical support request with Mathworks.

Answer from TS is "int" definition in audioPluginInterface works only inside Matlab environment (eg audioTestBench as Matlab Code or parameterTuner). When creating a vst (eg trough audiotestBench as VST or generateAudioPlugin command) the definition is lost (at least for display purpose). This will be raised to development team to be considered in future rel.
