snex_shaper

A SNEX node that can be used to implement waveshaping algorithms.
If you're writing a waveshaper that transforms the audio signal, you can use this class. It gives you a special callback and also a display that shows the waveshaper function.
Be aware that if you export this node to C++, it will use this class as template to create a full node, but in SNEX you don't need to supply the ShaperType template parameter.
The default code template forwards all rendering functions to a single getSample(float input) method. As long as you your algorithm is stateless, you can just implement the logic there, otherwise you have to adapt the boilerplate process calls accordingly:

// this will be called for every sample in every channel
float getSample(float input)
{
    return input;
}

// these callbacks just forward to the method above
template  void process(T& data)
{
    for(auto ch: data)
    {
        for(auto& s: data.toChannelData(ch))
        {
            s = getSample(s);
        }
    }
}

template  void processFrame(T& data)
{
    for(auto& s: data)
        s = getSample(s);
}
