![]() Its of no concern if the channel levels are where they should be relative to each other.Īs we (my wife & I) are learning more and more about this sort of thing every day, I'd love to ask what "nulling" files is? Given the context of our discussion, it seems to be some form of a technical comparison, but that's only a guess. 46): The level difference may well be nothing more than a slight difference in gain between how the OPPO handles optical playback vs USB playback. Regardless, I'm happy to learn more about DVDAE, but LuvMyQuad may have been right on when he wrote this earlier today (in Post No. 19 - and the rip that I made after selecting the DTS option.and that includes the absence of the "dts" symbol on the front panel of the Oppo 105D when the ripped FLAC files are played. Other than larger files sizes, there really isn't much difference between the original rip to FLAC - the one that I described in Post No. The sound levels coming from all four speakers is lower when playing the FLAC files than it is when the "DTS Surround" option is chosen before playing the actual DVD-A. Okay, so I ran DVDAE, after choosing the DTS option, and ended up with about the same thing. ![]() Finally, I have no experience with hardware players + USB playback, so I can't speak to what settings might affect that, either. We don't know what that is set to, though it seems perhaps to be 'DVD'? And of course there are likely channel level settings in the Oppo and AVR that could make some difference. ![]() There will also be a setting in the Oppo to choose 'preferred' layer when loading a DVDA - DVD or DVDA. It's also (still!) unclear whether lossy decoding is being done by the Oppo or by a downstream AVR decoder (i.e., whether the Oppo output is set to 'raw' or 'PCM'). DVD Audio Extractor is able to encode to several formats: OGG (Mono, Stereo or 5.1 Surround), MP3 (Mono, Stereo or Joint Stereo), Uncompressed PCM Wave (unlimited channel, 8 bits, 16 bits or 24 bits, with an option to save each channel to separate file), AIFF (only on OS X) and FLAC. He seems to have ripped the MLP version for starters, but is interested in the DTS. There are quite a few variables involved that would have to be eliminated before a useful diagnosis could be made. His initial impression was that the file playback level was lower than the direct. AFAICT, he wants to compare the output levels of AC3 or DTS decoded directly off the disc, to the same track played from a ripped file.
