Get actual waveform of audio?

[basilio4 (casey)]

Since PlaybackLoudness only returns the absolute value of the waveform, it won’t work for my application.
I’m looking to get (as close as possible to) the actual waveform of the audio.

example of problem:

this should be a sine wave

Has anyone come up with a workaround? or is there a different method to getting the value of a sample?

I do not believe this is possible through roblox. try finding an http that will return the data of the audio. because roblox does not give out audio data, and a 3rd party can analyze the audio.
