Hi

Can the EAC3to tool be used to downmix DTS 5.1 tracks to normal 2 Channel stereo wav? I need to listen some DTS 5.1 Stuff on the move. I wonder if anyone has the need for stereo downmix.

From the release notes I see that the EAC3to tool uses the Cinemaster Video/ Audio Decoder for DTS Decoding. I messed around the registry keys for the Cinemaster Audio decoder and found that the following key controls the DTS Decoding Options:

HKEY_LOCAL_MACHINE\SOFTWARE\Sonic\CommonMPEGDecoders\4.2\AudioDecoder\DTSOuputOptions. The default for the DTSOuputOptions is 0xb hex. I this is changed to 0x0 hex then the decoded output for a 5.1 Channel DTS file is a 2 Channel downmixed file. I'm not certain whether this is a downmixed output of just the Front Left and Right Channels.

Note that by changing this key value the output can be controlled to 2, 3, 4, 5 and 5.1 Channels.
