# Purpose
|
|
Run knn on audio data which has been converted to images to find similar audio clips
|
|
|
|
## Ffmpeg preporcessing command to create spectrogram image
|
|
Spectogramspectrogram
|
|
|
|
`for %f in (*.wav) do ffmpeg -y -i "%f" -ar 44100 -lavfi "showspectrumpic=s=256x256:scale=log:legend=0" "img\%~nf.png"`
|
|
|
|
With loudnorm to try to improve performance
|

## stb_image.h
|
|
Used for gathering the image data

|
|
|
|
### Todo
|
|
- [x] Load all images from directory
|
|
