 there's a bit of an explanation of each of the plugins below, but it's not a thorough documentation or a manual, it's just a bunch of notes i've written and a short description of the parameters

+simple (not accurate) sample rate changer

+params:
+- `repeats`: how many times to repeat a sample
+
+repeats a sample as many times as you tell it to, so if `repeats == 2.0`, and the inputs are `[0.0, 1.0, 0.5, 0.3, 0.4, 0.6, 0.7]`, it will play `[0.0, 0.0, 0.0, 0.3, 0.3, 0.3, 0.7]`. basically, `repeats == n` divides the sample rate by `n`
+
+it's not doing any actual resampling of audio

 ## contributing
 
 issues and prs are welcome, but please open an issue before making any big pr, i don't wanna have to reject a pr where you have put a lot of effort on. if you are fine with that, ig go ahead i'm not your mum
