Introducing pyatsyn: Python Implementation of the Analysis-Transformation-Synthesis (ATS) Spectral Modeling System
Are you searching for a Python library that enables you to analyze, transform, and synthesize audio? Look no further than pyatsyn! In this article, we’ll introduce you to pyatsyn, a powerful implementation of the Analysis-Transformation-Synthesis (ATS) spectral modeling system. Whether you’re a sound engineer, musician, or researcher, pyatsyn offers an array of features and functionalities designed to enhance your audio processing capabilities.
Features and Functionalities
pyatsyn provides a comprehensive set of tools for the analysis, transformation, and synthesis of audio. With the help of its sinusoidal plus critical-band noise decomposition technique, pyatsyn allows you to:
- Analyze recorded sounds and extract their spectral components
- Apply a wide variety of algorithms to transform the audio spectrum
- Resynthesize audio with precise control over time, both in real-time and offline
These features make pyatsyn a versatile tool for sound engineers, musicians, and researchers looking to manipulate audio in creative and innovative ways. Whether you’re interested in audio restoration, music production, or algorithm development, pyatsyn has got you covered.
Installation
To get started with pyatsyn, you’ll need Python 3.6 or later. While the library has been developed and tested on Python 3.9.15, it should work on any compatible Python version. pyatsyn also relies on the LIBSNDFILE library, which you can install using package managers like Homebrew (for Mac) or apt-get (for Debian-based systems).
To install pyatsyn, simply run the following command:
$ pip install pyatsyn
If you prefer using the command line, pyatsyn provides several included utilities that can be accessed through the terminal. These utilities include:
-
pyatsyn-atsa: Command-line tool for generating an ATS file with a residual from an input audio file. -
pyatsyn-info: Command-line tool for printing information about an ATS file to stdout. -
pyatsyn-synth: Command-line tool for synthesizing audio from an ATS file using various synthesis techniques.
These utilities provide a convenient way to interact with pyatsyn without writing any code.
Developer Instructions
If you’re a developer interested in contributing to pyatsyn or running it from source, you can clone the repository from GitHub using the following command:
$ git clone https://github.com/boxofbox/pyatsyn
We recommend running pyatsyn in a virtual environment. After cloning the repository, navigate to the project’s base directory and create a virtual environment:
$ cd pyatsyn
$ python -m venv .venv
$ source .venv/bin/activate
Next, install the required Python libraries using pip:
$ pip install numpy
$ pip install soundfile
If you want to generate the documentation, you can install Sphinx and the Sphinx RTD theme:
$ pip install sphinx
$ pip install sphinx_rtd_theme
Finally, to use pyatsyn as a package in development mode, install it using the following command:
$ pip install -e .
Following these instructions will allow you to work with the pyatsyn codebase and contribute to its development.
