+# Purpose
+Run knn on audio data which has been converted to images to find similar audio clips
+
+## Ffmpeg preporcessing command
+`for %f in (*.wav) do ffmpeg -y -i "%f" -ar 44100 -lavfi "showspectrumpic=s=256x256:scale=log:legend=0" "img\%~nf.png"`
+
+## stb_image.h
+Used for gathering the image data
+
+## Building
+`clang src/main.c -Iexternal -O2 -o soundknn.exe`
+
+### Todo
+- Load all images from directory
+- Do knn algorithm
+- Use opencl to accelerate algorithm execution
