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.
Spdifer is used automatically by DirectShow players (see a list of compatible Media players). Just open a media file with AC3 or DTS audio track.
To configure the filter run configuration utility from Start menu (All programs->Spdifer->Spdifer config).
NOTE! You should disable other AC3/DTS
decoders to prevent the decoding of the filter's output. To use Spdifer in conjunction with AC3Filter, disable formats enabled in Spdifer at the AC3Filter:System page and disable 'SPDIF' format too.
Supports passthrough for AC3, DTS and MPEG Audio formats. All passthrough features of the 'big brother'
AC3Filter filter are supported:
SPDIF as PCM trick
Sample rate check
Sound card reinitialization
