comsar — Computational Music and Sound Archiving
comsar is a Python toolkit for content-based analysis of music and sound, with a focus on ethnomusicology (timbre, pitch/melody, tonal systems, rhythm and corpus visualisation with Self-Organizing Maps).
It is the top layer of a three-package stack maintained by Rolf Bader:
| Package | Role | Repository |
|---|---|---|
| apollon | Backbone: audio I/O, feature extraction, HMM, SOM (C-accelerated) | codeberg.org/rbader/apollon |
| chainsaddiction | Poisson Hidden-Markov-Models in C (used for rhythm / time-series) | codeberg.org/rbader/chainsaddiction |
| comsar | High-level music analysis (PitchTrack, TimbreTrack, tonal systems, SOM) |
codeberg.org/rbader/comsar |
This fork combines the modern comsar code base with the pitch-tracking and
tonal-system analysis (PitchTrack) merged back from the older comsar version.
Distribution names. The original PyPI names
apollon,comsarandchainsaddictionbelong to the upstream authors. This fork is published asbader-apollon,bader-comsarandbader-chainsaddiction. The import names are unchanged: you still writeimport comsar,import apollon, etc.
Installation (no compiler needed)
Pre-compiled wheels are provided for Windows, macOS and Linux (CPython 3.9–3.13). Installing comsar pulls apollon and chainsaddiction automatically:
pip install bader-comsar
To also run the example notebooks:
pip install bader-comsar jupyterlab
For source builds, step-by-step Windows/macOS/Linux instructions, and troubleshooting, see the full manual.
Quick start
from comsar import PitchTrack, TimbreTrack
# Pitch / melody / tonal-system analysis
pt = PitchTrack()
result = pt.extract("my_audio.wav")
print(result.features) # pandas DataFrame
# Timbre feature track
tt = TimbreTrack()
timbre = tt.extract("my_audio.wav")
Runnable notebooks are in examples/.
