Dam1DASH

Dam1DASH is an open-source software framework designed to facilitate processing and visualization of one-dimensional data streams. It provides a modular architecture to build, test, and deploy real-time analysis pipelines for signals, time-series data, and sensor streams. The project emphasizes low-latency processing and reproducibility, with a dataflow model that connects processing blocks through a directed acyclic graph.

Origin and development: Dam1DASH was initiated in 2019 by researchers at the Institute for Computational Systems and released publicly in 2020 under a permissive license. It has since undergone several major and minor releases, expanding its runtime, language bindings, and example workflows.

Architecture and features: The framework combines a lightweight C++ core with bindings for Python and JavaScript. It provides modules for filtering, windowing, statistical analysis, and visualization; supports both real-time streaming and batch processing; offers pluggable backends for CPU and GPU execution; and includes pipeline descriptions in YAML or JSON.

Applications: Users apply Dam1DASH in experimental physics, seismology, environmental monitoring, and engineering to analyze time-series data, detect anomalies, and visualize trends. The project provides tutorials and example datasets to promote reproducible research and rapid prototyping of analytical workflows.

Community and licensing: Dam1DASH is distributed under the BSD-3-Clause license. It maintains an issue tracker, mailing list, and community spaces for contributors. User adoption has grown in academic labs and small-to-medium industry teams, though it remains smaller than established data-processing ecosystems.
