Okay so this is like a part two of my previous question that was closed. For a little background, I am attempting to match an input from a bass, connected to my pc via an interface (Scarlett Solo), to a certain note with reliable results. I was suggested to use the YIN pitch detection algorithm after I was trying to use just plain Fourier Transforms.
Since I'm writing in rust, I'm using a rust implementation of the algorithm.
Trying to use the example that's provided with the crate, returns an estimated frequency of -1 no matter how many times I strum the bass which, after reading the source code, means that tau_max is higher than the audio_sample.len(). I have been debugging the best I can, emphasis on "I". So here's the info I've gathered so far:
Input:
Sampling Rate: 44100hz
Sample Length: 882
For standard tuning, I would be led to believe that the freq_min should be around 40.0hz and my freq_max should be around 444.0hz. For an example:
Yin parameters:
Threshold: 0.1
Freq_Min: 10.0
Freq_Max: 100.0
Sampling Rate: 44100hz
