Panako doesn't recognize pitch and speed differences #44

I tried Panako to compare 2 audios which are

1. different with pitch (I used ([https://vocalremover.org]) to change pitch), but Panako didn't recognize it.
2. different with speed (I used [https://vocalremover.org] to change speed), but they haven't recognized as well.

I think the problem here can be peak picking algorithm. Because when I print triplets, all peaks are different in some examples with frequency and in some examples with time. What can be a problem?. Because the paper which describes Panako assures that type of differences are catchable.
