Installation

Example Code

Score

Get the individual frames of the score into output directory outdir:

from amusing.score import Amusing, Note

WIDTH_IN_PIXELS: int = 1820
NUMBER_OF_THREADS: int = 8

MUSESCORE_FILEPATH: str = 'score.mscx'

QUINTUPLET: float = 4/5

amusing = Amusing(width=WIDTH_IN_PIXELS,
                  outdir='frames',
                  threads=NUMBER_OF_THREADS)
amusing.read_score(MUSESCORE_FILEPATH)
amusing.add_job(measures=1,
                subdivision=Note.n16th)
amusing.add_job(measures=[2, 3],
                subdivision=Note.QUARTER * Note.TRIPLET)
amusing.add_job(measures=range(4, 7),
                subdivision=Note.EIGHTH * QUINTUPLET)
amusing.generate_frames()

Delete all jobs:

amusing.delete_jobs()

Munim

Music Animation

Render video of the frequency spectrum using Morlet wavelet

from amusing.munim import Morlet

AUDIO_FILEPATH: str = 'example.mp3'
TO_VIDEO_FILEPATH: str = 'example.mp4'

morlet = Morlet(fps, width, height)
morlet.read_audio(AUDIO_FILEPATH)
morlet.transform()
morlet.render_video(TO_VIDEO_FILEPATH)

Using Short-time Fourier Transform (STFT)

from amusing.munim import STFT

morlet = STFT(fps, width, height)
morlet.read_audio(AUDIO_FILEPATH)
morlet.transform()
morlet.render_video(TO_VIDEO_FILEPATH)

2d-Oscilloscope:

from amusing.munim import Oscillate

oscillate = Oscillate(fps, width)
oscillate.read_audio(AUDIO_FILEPATH)
oscillate.render_video(TO_VIDEO_FILEPATH)

Introduction

• programmatic animation of sheet music
  • notes appearing consecutively
  • uses MuseScore as notation software

Animation

Score

• generates full resolution frames of the video
• not synchronized to audio

Munim

• audio visualization
  • STFT
    • linear spectrum
  • Morlet (DWT)
    • arbitrary spectrum
    • implemented logarithmic
  • 2D Oscilloscope

ToDo

• increase efficiency of making the score
  • OMR, e. g. Audiveris
• programmatically combine frames to high quality video
  • automatic synchronization to audio
    • DWT where Wavelet function is a sample of the instrument sound
    • Deconvolution of overtones
• add background interest
