built-in MIC pitch problem

drumbox777

Hi everybody,
I am trying to make a sampler-keyboard using the Orange Pi Zero and pure data, meaning that I want to be able to record sound from the input and play it back, when I want.Because the OPI Zero only has the MIC as input, that's what I am using. But the sound of the MIC seems pitched up and I can barely understand my voice on the recordings. I don't expect the audio quality to be very good, but I can't imagine that it is supposed to sound this bad.

What are your experiences with the built-in Mic?


Are there workarounds for this?

Thanks for reading!
