Hello

I am using raw amplitude and frequency (env~ and fiddle~ respectively) to make real time adjustments to images. My problem is that the changes being made are either to drastic in a very short amount of time or hardly any change at all. So what I end up with is almost a strobe light effect or the changes are so minimal it is almost not noticeable.

The image sources are in jpeg

The audio sources are a microphone and a wav file

I am feeding the data into these objects to manipulate the pictures:

pix_lumaoffset
pix_convolve 3 3
pix_contrast
pix_bitmask

and possibly others...

Is there any way to take a value range of 0.1 to 3.0 and exaggerate the top half of the value range. So that lets say 1.5 to 3.0 seem to be far greater then they really are after being scaled? Finally I would like everything below the threshold of around 1.5 to be literally 0.1 to 1.5.

Thank you!

maybe have a look at [mapping/exponential_curve].

AudioLemon,

Thank you so very much! I was able to achieve the exact effect I am looking for.

You just helped me get around a huge roadblock to my project.

I was able to get an exponential curve going to the input data however the changes were still not drastic enough. I resolved this by creating a second

[mapping/exponential_curve] object to control the first one's

double-exponential seat control parameter using the same input data, from the RMS Amplitude of an audio source.

Thank you again!,
