Re: [SurroundSound] Re: How to identify

Dts is lossy, compressed.  When it is decoded to .wav, it is still  lossy but now decompressed. Therefore much larger.  Flac is lossless compression, so it will produce a file that is as much as 50% smaller than the .wav but still much larger than the .dts.   Because no data are discarded.

I recently converted some dts.wav files to dts.flac and the file size increased threefold too. This is because .dts is a compressed and lossy format, flac isn't lossy (thanks Ben). I believe some folks prefer the ability to Tag flac files for their library over the bigger file size

That doesn't sound right (no pun intended)!  Compressing a DTS-WAV file with FLAC usually results in a few percent size reduction, so something is wrong with a 3x expansion!  My guess is that AudioMuxer is not losslessly compressing using FLAC, but in fact *converting* the source file to some other format, e.g. multi-channel FLAC.

My recommendation would be to download/install the official FLAC utility (https://xiph.org/flac/download.html, downloading both FLAC for Windows [command-line tools only] and FLAC Frontend, [GUI for the official FLAC tools]), and compress your source file to FLAC using the GUI.  Be sure to first de-select Replaygain, since ReplayGain would destroy the DTS encoding during playback on any decent player (that honours ReplayGain).

I don't know if your budget stretches to a new surround receiver or pre-processor, or whether you might be looking at older second-hand surround receivers.  If the latter, JVC has the best DTS-handling of the major brands I've tested (which includes Sony, Pioneer and Onkyo, none of which correctly switch between DTS and stereo when fed with a non-break bit-stream of mixed-mode music, i.e. a shuffled playlist containing both stereo and DTS tracks without any break between their bit-streams).

When converting a DTS.WAV file to Flac 6 channel with AudioMuxer the size is 3 times bigger then the WAV one :O
