dttlib

What it is and what it does

dttlib is a Python wrapper around LIGO's core diagnostic and analysis library, providing frequency-domain tools for processing gravitational wave detector signals. It integrates with LIGO's standard C libraries (libcds, libgds-sigp) and uses FFTW for fast Fourier transforms, enabling both online and offline analysis workflows. The package targets researchers and engineers working with LIGO data who need FFT-based diagnostics and swept-sine measurements.

The package has medium install friction because it depends on several system-level C libraries that must be pre-installed and available in the build environment. It supports Python 3.9 and later across macOS ARM64 and Linux x86_64 platforms via pre-built wheels. No runtime Python dependencies are declared, keeping the runtime footprint minimal once the C libraries are satisfied.

Use it for:

• Perform real-time frequency-domain diagnostics on LIGO detector signals during observation runs
• Analyze archived LIGO data offline using FFT-based methods for signal characterization
• Conduct swept-sine measurements to characterize detector response across frequency bands
• Integrate frequency-domain analysis into LIGO data pipelines and monitoring systems

AI-flagged interpretation of the facts on this page — verify before relying

dttlib provides frequency-domain analysis tools for LIGO gravitational wave detector data, supporting FFT-based diagnostics and swept-sine measurements.

Yes, if you work with LIGO data and have the required C libraries available. The package is actively maintained, has no known vulnerabilities, and fills a specialized role in gravitational wave data analysis. The main barrier is satisfying system C dependencies and the unclear license status—verify licensing compatibility before use in restricted contexts.

Install

dttlib on PyPI

pip install dttlib

uv add dttlib

poetry add dttlib

Installing dttlib

Before you install

Medium install friction due to compiled C dependencies (libcds, libgds-sigp, libfftw3, libglib-2.0, libstdc++, libsasl2, libz, libexpat) that must be available on the system. Package is actively maintained with recent releases.

License in practice

License status is unclear—no SPDX identifier or raw license text is available in the package metadata. Verify licensing terms before use in proprietary or commercial contexts.

Quickstart

pip install dttlib
import dttlib
# Use dttlib for LIGO frequency-domain diagnostics

Requires system C libraries: libcds, libgds-sigp, libfftw3, libglib-2.0, libstdc++, libsasl2, libz, libexpat. Python >=3.9 required.

Verify before relying

• Specific API surface and available functions for frequency-domain analysis beyond FFT and swept-sine
• Whether diaggui integration is a separate tool or included in dttlib
• Performance characteristics and typical data volume handling
• Community adoption and usage patterns within LIGO collaboration
