DSPde

DSPde is an open-source software project and development environment designed for digital signal processing across embedded and desktop platforms.

The project provides a modular, cross-platform library of DSP algorithms including finite impulse response (FIR) and infinite impulse response (IIR) filters, fast Fourier transform (FFT), wavelet transforms, resampling, and adaptive filtering, along with a graph-based workflow for building DSP pipelines.

Architecture-wise, it centers on a core engine that handles data flow, scheduling, and memory management, a plugin system for new algorithms, and language bindings for C, C++, and Python; builds are portable with CMake and include SIMD optimizations for x86 and ARM.

History and license: DSPde originated in 2019 as a community project of researchers and engineers seeking accessible, reusable DSP components; development is community-driven with open contributions on a public repository and a permissive MIT-style license.

Usage and impact: DSPde is used in academic courses and research projects to prototype audio, communications, and sensor-processing algorithms; its graph-based workflow supports rapid testing and integration into larger software stacks.
