I looked online and didn't find anything definitive, they all wanted to compare the source and changed data structures and listen for differences....which I would consider too subjective to yield any factually grounded answers.
I feel like there should be a straight yes or no answer to this question. If I make a recording of a track in audacity for example. And then I use amplification to any extent short of clipping, am I losing quality from the original recording upon export? (I'm recording at 48hz and 32bitfloat, so I understand that even without amplification my export will lose quality unless its a wav f32 or higher format export.)
What is amplification doing exactly? Is it simply stretching existing finite data or recalculating the data to fit a larger model? The former would, to me, imply quality loss.
