Utilities for sound, music notation, acoustics, etc
Project description
- maelzel is a framework for doing computer music in python. It is
based on a core package, which provides datatypes to define notes, chords, sequences, lines, voices, scores, etc. Other modules provide functionality for working with sound (loading soundfiles, working with samples, applying filters, fading, mixing, playback), sound analysis, music, acoustics, music notation, etc.
Documentation
Structure
core: core module defining basic classes for computer music (Note, Chord, Voice, Score, etc). Any of these objects can be representated as notation and played back.
snd: read/write soundfiles, process samples, apply filters, fades, etc.
music: music representation, algorithmic music, etc
scoring: music representation. Offers support for microtones (up to 1/8 tones or any cent deviation), very refined cotrol of automatic quantization, glissandi, grace-notes, annotations, etc. Supports multiple backends (lilypond and musicxml at the moment).
acoustics: formulas for helmholtz resonators, speed of sound, etc.
midi: read/write midi files, general midi
ext: wrappers around external software, like sonic-visualizer, audacity, reaper
Installation
pip install maelzel
Dependencies
csound (>= 6.16)
Optional Dependencies
MuseScore (for rendering musicxml to pdf when using the musicxml backend)
