Hi,

Yesterday I did my first tests in converting a DTS MA audio track to a multichannel flac, which works fine at all. Nevertheless, when the converting process was finished, I ended up with a flac file, which has a bitdepth of 24bit, while eac3to told me, that the bitdepth of the original track was only 16bit. Since using 24bit in the flac file is a waste of space when the original bitdepth is only 16bit, I repeated the process using the -down16 parameter, and now everthing is fine. Both the original DTS MA audio track an the resulting flac file have the same bitdepth of 16bit.

That brings up the question:

Is it possible to use eac3to in a way, where a lossless track, like Dolby TrueHD or DTS MA, is decoded and analysed for it's bitdepth, while the resulting data is not written to the hdd and discarded instead ? This would make it possible to do a faster first pass to scan the track for it's bitdepth, and then do a second pass to convert the track in a flac file of the original bitdepth.
