PandaResampler 0.2.1 has been released. https://github.com/swesterfeld/pandaresampler This is a header only library for C++ which implements fast factor 2, 4 or 8 upsampling and downsampling based on SSE instructions. I've developed the code for my DSP code in Anklang and SpectMorph. It might be useful for you if you have some DSP loop which needs to be oversampled to avoid aliasing. Changes in PandaResampler 0.2.1: -------------------------------- * Use meson build system. * Improve test coverage and CI tests. * Support building a shared library (#3). * Do not build tests unless -Ddevel=true is used (#2). * Install headers to include install directory from meson (#1). -- Stefan Westerfeld, http://space.twc.de/~stefan
