Software Dolby Digital Live / DTS Connect-style encoder for Windows: a virtual 5.1 audio device that encodes any multichannel PCM to AC3 (Dolby Digital) in real time and streams it over S/PDIF (Toslink/optical) to an AV receiver. FFmpeg AC3 + WASAPI exclusive passthrough; a SoundPusher-for-Windows approach.
