wavChecker features

If there is a difference, it displays the difference in each frame based on TC.
This is not　"wave inversion check."
Complete binary check is performed. No misjudgment will occur except for bugs.
Checking process is very fast, because it does not perform any wav decoding process,
so it can check in a few minutes even if the length of the file is longer than 2 hours.
