In my view I need to visualize some audio data as waveform. I also want to make pinch-zoom in/out possible. how could that be realized? Is there any knowledge around?

Once you have the audio sample data, I use the approach here.
To display more or less samples than points, use interpolation or the peak sample value. Reserve a lot of time for optimization if you want good performance over many samples.
