this was kind of non obvious to me, but the sample count you get from a clip is for one channel.
Meaning you'll have to multiply it by the amount of channels when preparing the array for GetData.
It's in the example code (new float[audioSource.clip.samples * audioSource.clip.channels];) but I somehow missed it and took me a while to figure out.

Sometimes I find (maybe only with ogg format?) that the number of samples available to GetData() is actually 1 sample less than would be calculated via clip.samples * clip.channels. I get the warning

Data longer than the AudioClip: . 10434229 sample(s) copied

See how in that example the number of samples copied is an odd number, even though there are 2 channels.
Also, the documentation seems to by lying about wrapping around? (thankfully!)
