Fibonacci stretch the first 90 seconds of Michael Jackson's "Human Nature" by a factor of 1 using input rhythm [1,0,0,1,0,0,1,0]:
import fibonaccistretch as fib
fib.fibonacci_stretch_track("data/humannature_90s.mp3",
original_rhythm=[1,0,0,1,0,0,1,0],
stretch_factor=1,
overlay_clicks=True)Take a listen to the result.
See fibonaccistretch.ipynb for a more detailed writeup and implementation (note: the outputs are cleared, so to see figures and listen to audio you'll need to run the notebook using Jupyter). A static HTML version is also available here.
