filterssupport

Filterssupport is a modular software library conceived to provide a unified framework for implementing, configuring, and orchestrating filters across data processing pipelines. It emphasizes a standard interface for different filter implementations and a composable approach to building processing chains, enabling reuse and interoperability in areas such as signal processing, data cleaning, and real-time streaming.

The project originated in open-source discussions about reducing fragmentation in filter code. It is designed to be language- and platform-agnostic, with core concepts expressed as a language-neutral API and with bindings or adapters to common programming languages. It aims to support both classical digital filters and higher-level data transformation operators.

Key features include a core Filter interface with methods for processing samples, configuring parameters, and resetting state; a set of built-in filters such as low-pass, high-pass, band-pass, and moving-average; a plug-in mechanism for third-party filters; and a filter-chain construct that connects multiple filters into a pipeline. The configuration system supports serializing pipelines to JSON or YAML and restoring them at startup. There are utilities for testing, benchmarking, and validating numerical stability. The project also provides bindings to Python, Java, and C++, and optional bindings for embedded environments.

Usage generally involves defining a filter chain, wiring it to a data source, and iterating over the processed output. While Filterssupport is a fictional concept used for illustrative purposes, the design demonstrates how a centralized, extensible approach to filters can reduce duplication and improve maintainability in complex data workflows.
