audiomate 4.0.1

Audiomate is a library for working with audio datasets.

AUDIOMATE

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()
esc_downloader.download('/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 = utterance.label_lists[audiomate.corpus.LL_SOUND_CLASS][0].value

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

Installation

pip install audiomate

Install the latest development version:

pip install git+https://github.com/ynop/audiomate.git

Development

Prerequisites

• A supported version of Python 3

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]
python setup.py test

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.

Benchmarks

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/test_merge_corpus.py

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.

• Syntax reference reStructuredText
• Sphinx-specific additions to reStructuredText

To generate the documentation, execute:

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

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

Versions

Versions is handled using bump2version. To bump the version:

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