xpresso Sound node “sample” port useage

Hello,

I know this node is quite esoteric and pretty much nobody uses it since the output can’t be rendered.
However, I noticed that this node has a port called “sample” and the help file states you have access to each sample in the audio file.
So I tried inputting some constants to see if the magnitude would be output at these specified sample indices and I get nothing..

Its a long shot but I was wondering if anyone has any experience getting audio magnitude data at a sample level?
I’d like to make an accurate audio waveform by iterating samples at the correct project speed relative to iteration size.

Alternatively, is it possible to get any data from the special timeline “Sound” in c4d?
AFAIK the sound effector doesn’t offer sample level audio data.

One alternative I’ve thought of so far is to just use the sound effector and up the project frame rate and use frame skip, not sure if this would affect motion blur though or have other unwanted effects..

Best,
Nick
