Oh, I forgot to add that I didn’t normalize anything before going into `fluid.umap~`. So the MFCCs are in whatever weird range they are, the loudness is in dB and pitch is in MIDI.

So the data looks something like this (the rows are in [random order](https://discourse.flucoma.org/t/fluid-dataset-json-save-sorting/782/5)):

```auto
rows: 1715 cols: 21
1 7.5122 -18.776 -12.415 ... -0.27735 87.31 -53.293
10 1.5144 -18.605 -9.722 ... 0.38857 93.144 -56.418
100 1.0442 -10.104 -9.5277 ... 0.35186 77.097 -33.9
       ...
997 4.6128 0.61793 2.3301 ... -1.5062 95.02 -47.25
998 5.323 -0.35285 -2.2085 ... -0.36513 86.027 -42.957
999 3.578 -2.352 -2.4126 ... -1.4234 83.26 -47.525

```

I will have some more detailed questions about the best way to approach this in another thread, as part of me building this was to make an IQR-based rescaler, so I wanted to be able to visualize what is happening throughout the process.

On that note, and out of curiosity I plotted some variations of this dataset.

Here is the 21D space (20MFCCs (19), loudness, pitch) mapped via 3D umap (what’s displayed above essentially):
