In depth
A closer look at Spdifer
Spdifer was designed to be a DirectShow filter that will allow media players to passthrough multi-channel sound to the digital (SPDIF) output without any change, so an external receiver can decode it. To use this filter just select the formats you want to passthrough, and it will be used by the player automatically. NOTE! You should disable other decoder filters to prevent the decoding of the filter's output. To use Spdifer in conjunction with AC3Filter, disable formats enabled in Spdifer at the AC3Filter's 'System' page, and disable 'SPDIF' format. Supports passthrough for AC3, DTS and MPEG Audio (including mp3) formats. All passthrough features of the 'big brother' AC3Filter filter are supported:
