Voice samples sounding gravelly

[Zansatsu]

Hey everyone, a friend of mine provided the voice for a new utau of mine. Her samples sound fine when I play then but when I open up the voicebank some of the samples sound gravelly for some reason and I'm not sure what it could be.

I generated an oto with OREMO for the voicebank but I don't think think the oto is what's causing the gravelly sound. Or maybe it is, I'm not sure. Or if it's the quality of the recordings

Does anyone know what might be causing this?

It'll be easier to diagnose the problem with an actual audio sample. You might be having FRQ problems, so see if switching to a resampler that doesn't use FRQs (like TIPS or moresampler) changes the result.

I'll try and check to see if that's what's causing the problem. I would've uploaded an audio sample but i'm not home atm lol

I can upload one when I get back though
