FLAC compression is like a "zip" file on a computer - it is a lossless way of storing data with mathematical formulas instead of the raw data of the wave form. This is different from .mp3 compression that actually eliminates data points and relies on an algorithm to draw a new wave form. In FLAC compression, the higher the compression, the more time the processor will take to "unzip" the file.
However, once "unzipped" the raw data is the same as the original wave form, regardless of the compression level.
