From the developer:
Spdifer is a DirectShow filter that allows media players to passthrough multi-channel sound to the digital (SPDIF) output without any change, so an external receiver can decode it.
Supports passthrough for AC3, DTS and MPEG Audio (including mp3) formats. All passthrough features of the 'big brother' AC3Filter filter are supported:
- SPDIF as PCM trick
- DTS output mode change
- Sample rate check
- Sound card reinitialization
