wav samples not working

[BlueDawn226]

im playing spectrobers 1 on windows 10, melonds 1.0 rc
The game requires using the mic to pass a certain tutorial where you have to maintain the sound on a certain level (represented by bars filled depending of your voice volume)
im using the following samples (the 8 and 13 on the file name represent how much bars that specific file fills)

basically the wav injection doesnt work, usually it doesnt even fill the first bar, but i have some instances when it fills some bars on a erratic way, as if it was picking sound intermittently
Tried external mic and blow noise and those dont work either

update: seems like melon ds 0.9.5 works flawlessly
