oppai-chunks

Calculate the difficulty over time of a beatmap with moving windows.

Runs on Python 3 and uses oppai

Usage:

From the command line

./oppai_chunks.py beatmap [window [step]]

beatmap is the .osu file you want to analyze. window is the window size to use, in milliseconds.

step is the step size to use, in milliseconds.

For example, ./oppai_chunks.py "haitai.osu" 12000 2000 will calculate the difficulty from 0:00 to 0:12, then 0:02 to 0:14, and so on.

As a python module

from oppai_chunks import oppai
...
oppai(beatmap, window=30000, step=5000)

The arguments are the same as above. Here, the beatmap can be given as a path (oppai('/path/to/beatmap.osu')), or as the contents of an opened file (oppai(file.read()), oppai(file.readlines())). The output is a list of (time, overall stars, aim stars, speed stars) tuples.
