The initial check is done by looking at the waveform here on looperman.
By that i mean that the file suffers from one of the following problemsĮxtra space at the beginning or end a tail left on, caused by reverb or delay files not being 2, 4 or 8 bars When checking the loops that users upload the most common problem is files that are not perfect loops.
