asplib (Achim's Signal Processing LIBrary)

Is a small and lightweight C++ library for digital signal processing.

Projects using asplib

• adsp.xconvolver (Convolution Engine AudioDSP-Addon for Kodi with several platform optimizations)
• adsp.biquad.filters (Graphical Equalizer AudioDSP-Addon for Kodi with several platform optimizations)
• PictureIt (Gaphics library to render images and audio spectrum which is used by visualization.pictureit)

Features

• all needed functions for BiQuad-Filter calculation
• constant Q peaking filter coefficient calculation
• Easy and well designed API

Planned Features

• LibXConvolver (FIR-Filters, fast non-uniform/uniform convolution) integration
• More IIR-Filter design functions (Low-, High-, Band-, Notch-, Allpass filters)
• Benchmark framework
• logging functions
• dynamic library and static library builds
• REW (Room Equalizer Wizard) filter file import
• Digital Delay Lines
• Dynamic Processors (AGC, Compressor, Limiter, Expander and Noise-Gate)
• Peak Level estimation
• Native (C++-Classes), SSE2, SSE3 and AVX-optimizations
