A quick question:
In Vanilla, is it possible to bias solely the display of a waveform in an array in such a manner, that lower volumes visibly appear louder than they are?
Or can i only do that by copying the data into a second array and altering such data to fit my display needs?
Very dynamic audio often would love such a display feature here, however without touching the actual data - and copying large arrays of audio likes to incite dsp dropouts.
Thank you in advance for your expertise,

logarithmic scale on the y-axis (or x-axis, for spectral info)? i'm afraid, the answer is "no" (so you have to perform any data mangling first, and then show it on a 2nd display-only array)

it shouldn't take much longer than filling the primary array though. so if you are able to do this without dropouts, you should be able to do the data mangling as well. that is: if you are recording live into the primary array, do a simultaneous recording of the mangled data into the secondary array.
if this is not an option, you might want to check the "iem_tab" library.

I'd make a transfer function in the style of waveshaping and use the audio you want to draw to read it and display the output.
It should not be more computationally expensive than a wavetable oscillator.
Best,
