pix_spetrogram

I am developing this object for two reasons, a set of poems for victor zue and because many times I need to see a spectrogram in Pd and don't want to graph outside.

This object is still in development, I am mainly working on the help patch to have some manageable and interactive GUI. I hope to release a stable version in the following month, since it is a tool I am in need of using lately. However if you find yourself urging one of these, send me an e-mail and I'll send you what I have which is basically what you see here.

This object receives as input a black image and outputs a spectrogram.

The second crucial input (second inlet) is the result of an fft analysis. (the one you see prepended is the mode the object is in, mode 1 is black and white)

Finally it has other parameters for the quality of the image in its third through sixth inlet: brightness, contrast, saturation, alpha.

The interactive GUI I was talking about is briefly represented in the pictures on the left. The second one shows the spectrogram with no zoom.

The third shows some zoom and the fourth shows zoom and shift to the right.

These are the less developed features, mainly because of a lack of time. Other features on the work are interactive scales to get Hz and time.

Finally, I am also working in pix_invertspectrogram which will do the opposite, feed an image, adapt to ifft input and output a sound...
