I think that's all covered in the specifications I have, however. (That document just doesn't cover embedding in IEC61937.)
I know roughly what needs to be done, and I can create (from the DTS data ripped from DVD) files which the receiver recognise as DTS, and which I can hear contain the right audio -- but at the wrong speed, or stuttering, or only for a few seconds. By comparing my output to that of a DVD player (which I _know_ gets it right) I should be able to work out what's going wrong. > BTW, it would be nice for any server-side processing of DTS-WAV's or > more likely DTS-flac files to use embeddded meta data to tell the SB2 > to disable the digital volume control and pass the data through > unattenuated. > > At the moment, for the 1 demo file I have from Kelly Industries, I have > to set the volume control from the Web UI whenever I want to show off > the SB2. Sean mentioned some other things the firmware could do when it spots such a file, so that suggestion could go on that list. I'd not considered that myself; I've set the player's digital volume to be fixed, and use a universal remote with the volume controls punched through (so they work no matter what mode the remote is operating in). Not a solution for everyone, of course! That's made me think... I'll try disabling ReplayGain altogether and try my files out again. I'd be very surprised if it made a difference (there's no RG values in my WAV files; I don't think the format even supports storage of same) but I'd better be sure. That does highlight a weakness in one's overall setup with regard to DTS/DD files: we can't apply ReplayGain to them, as such an adjustment would break the data. Having said that... the AC-3 format (used for Dolby Digital) does carry an indicator of loudness, which should be respected by the sound reproduction equipment... I wonder if that could be tweaked to normalise it somewhat? That's pie-in-the-sky at the moment, but I may look into that once I've got the basics sorted. :) -- smst _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
