Last night, took a random sample from a discord I'm on and ran it through my DSP project to see what it would sound like.

Opened the resulting wav in RX9 and saw the wav looked mad; huge DC offset in the samples 🤔

Turns out the original sample had a small DC offset (0.03%) and time stretch + grains amplified it to 17%!

So, anyway, I've now got some DC offset filtering code aka a simple first order high pass to take out super low frequencies (sub-20hz or so) - problem solved👍

I've been learning about resampling and I've got some nice spectrograms. if you want to take a sample and play it back at a different pitch, there's a surprising amount of work involved to make it sound good

i'm doing a similar test as described here:
jeskola.net/xs1/content/test/
15khz tone pitched up through an octave and then down. some of the notes are above the nyquist frequency (half the sample rate) so shouldn't be there at all ideally.

first, zero-order hold i.e. skipping or repeating samples as necessary. unusable unless you're making chiptune.
second, linearly interpolating between samples, still very bad
