Audiomate is a library for easy access to audio datasets. It provides the datastructures for accessing/loading different datasets in a generic way. This should ease the use of audio datasets for example for machine learning tasks.

import audiomate
from audiomate.corpus import io

# Download a dataset
esc_downloader = io.ESC50Downloader()'/local/path')

# Load and work with the dataset
esc50 = audiomate.Corpus.load('/local/path', reader='esc-50')

# e.g. Read the audio signal and the label of specific sample/utterance
utterance = esc50.utterances['1-100032-A-0']
samples = utterance.read_samples()
label_list = utterance.label_lists[audiomate.corpus.LL_SOUND_CLASS]

for label in label_list:
  print(label.start, label.value)

Furthermore it provides tools for interacting with datasets (validation, splitting, subsets, merge, filter), extracting features, feeding samples for training ML models and more.

Currently supported datasets:

Currently supported formats:


pip install audiomate

Install the latest development version:

pip install git+



For parts of the functionality (e.g. audio format conversion) sox is used. In order to use it, you have to install sox.

# macos
brew install sox

# with support for specific formats
brew install sox --with-lame --with-flac --with-libvorbis

# linux
apt-get install sox

# anaconda for macOS/windows/linux:
conda install -c conda-forge sox



It’s recommended to use a virtual environment when developing audiomate. To create one, execute the following command in the project’s root directory:

python -m venv .

To install audiomate and all it’s dependencies, execute:

pip install -e .

Running the test suite

pip install -e .[dev]

With PyCharm you might have to change the default test runner. Otherwise, it might only suggest to use nose. To do so, go to File > Settings > Tools > Python Integrated Tools (on the Mac it’s PyCharm > Preferences > Settings > Tools > Python Integrated Tools) and change the test runner to py.test.


In order to check the runtime of specific parts, pytest-benchmark is used. Benchmarks are normal test functions, but call the benchmark fixture for the code under test.

To run benchmarks:

# Run all
pytest bench

# Specific benchmark
pytest bench/corpus/

To compare between different runs:

pytest-benchmark compare

Editing the Documentation

The documentation is written in reStructuredText and transformed into various output formats with the help of Sphinx.

To generate the documentation, execute:

pip install -e .[dev]
cd docs
make html

The generated files are written to docs/_build/html.


Versions is handled using bump2version. To bump the version:

bump2version [major,minor,patch,release,num]

In order to directly go to a final relase version (skip .dev/.rc/…):

bump2version [major,minor,patch] --new-version x.x.x


Commands to create a new release on pypi.

rm -rf build
rm -rf dist

python sdist
python bdist_wheel
