comparison layer/SpectrumLayer.cpp @ 592:a13aa5320221 sonification

Extends the audio feedback of the piano scale to the Spectrum layer (horizontal piano keyboard).

Increase of the piano keyboard width (SpectrogramLayer) and height (SpectrumLayer) for layout purposes. A get method should be added to obtain the scale size parameter outside the layer class.
