Detailed Description

A Voice Processor class.

A virtual base class for a voice manager implementation.

The idea behind this class is to make it easier to support either single precision or double precision samples (float or double) or different channel layouts.

Example:

//------------------------------------------------------------------------
class MySynthProcessor : public AudioEffect
{
public:
    tresult PLUGIN_API setActive (TBool state);
    tresult PLUGIN_API process (ProcessData& data);

protected:
    VoiceProcessor* voiceProcessor;
};

tresult PLUGIN_API MySynthProcessor::setActive (TBool state)
{
    if (state)
    {
        if (processSetup.symbolicSampleSize == kSample32)
            voiceProcessor = new VoiceProcessorImplementation<float, Voice<float>, 2, MAX_VOICES, void> (processSetup.sampleRate, 0);
        else if (processSetup.symbolicSampleSize == kSample64)
            voiceProcessor = new VoiceProcessorImplementation<double, Voice<double>, 2, MAX_VOICES, void> (processSetup.sampleRate, 0);
        else
            return kInvalidArgument;
    }
    else
    {
        delete voiceProcessor;
        voiceProcessor = 0;
    }
    return kResultTrue;
}

tresult PLUGIN_API MySynthProcessor::process (ProcessData& data)
{
    return voiceProcessor->process (data);
}
