About

The goal of LXC (LibXConvolver) is to create a cross platform library for fast convolution (http://en.wikipedia.org/wiki/Convolution). LXC will be available on Windows and Linux. If it is possible I will port it to Android, iOS and MacOSX.

LibXConvolver will support Native (C implementation), SSE2, SSE3, SSE4, AVX, AVX2, CUDA, OpenCL, ARM_VFP and NEON instructions.

But the first step is to release a convolution addon for Kodi's new Audio DSP system (for more details see http://forum.xbmc.org/showthread.php?tid=186857).

LXC Software Architecture

Dependencies

  • fftw
  • KissFFT
  • libsndfile
  • libsamplerate

Done

  • download build dependencies with scripts
  • include compiler flags to select for which platform the library will be build
  • implement convolution algorithm with Native and SSE3 instructions

ToDos

  • write API documentation
  • implement convolution algorithm with SSE2, SSE4, AVX, AVX2, CUDA, OpenCL, ARM_VFP and NEON instructions
  • port library to Linux, MacOSX, iOS and Android
