This program will convert just two channels to full 7.1 covered surround scene. Real psychoacoustics on the fly. Absolutely new technology by phase interference and partial time shifting. Source channels dividing to fifty virtual channels to make their magic and combine to 7.1 You have to use "Equalizer APO" as engine. Please install it before continuing. https://sourceforge.net/projects/equalizerapo/

ffdshow is DirectShow and VFW codec for decoding/encoding many video and audio formats, including DivX and XviD movies using libavcodec, xvid and other opensourced libraries with a rich set of postprocessing filters.

LSP (Linux Studio Plugins) is a collection of open-source plugins currently compatible with LADSPA, LV2 and LinuxVST formats. Standalone plugins for JACK are provided since version 1.0.8. Experimental support of ARMv7 added since version 1.1.4 Experimental support of AArch64 added since version 1.1.9 Decomposition of modules and new UI introduced in 1.2.0 Added CLAP support in 1.2.5 Added VST3 support in 1.2.15 The basic idea is to fill the lack of good and useful plugins under the GNU/Linux platform. After some contributions to other open source projects the decision was made to implement separate and independent plugin distribution.
