If you're concerned about too much dynamic range, not including the LFE channel when downmixing might be a good idea. By default eac3to doesn't include the LFE channel when downmixing to stereo. You need to specify -mixlfe in the command line eac3to is a freeware application that is capable of converting E-AC3, TrueHD, PCM and DTS-HD audio tracks to AC3, DTS or FLAC. Though eac3to is a command-line application, also included on this site is a download for the EAC3toGUI application which makes using eac3to much easier inside of a graphical user interface
. It analyses the audio in order to adjust it to a specific target volume according to how loud it actually sounds, and it works very well. I'd probably downmix with eac3to to something lossless like FLAC, then open the FLAC file with foobar2000 and run a ReplayGain scan Software needed to run eac3to . Taking the most out of eac3to involves using several external filters.

How to properly downmix 5.1 to stereo? Hi, I have pretty much declared from my own personal tests that 5.1 is pretty much useless and I can simply use stereo AAC-LC at 320kbps and it sounds identical to 5.1 when under headphones In Tools window click Downmix tab. To conversion of channel number check Downmix to stereo switch. To keep original channel number uncheck the switch. Select mixing mode (see details below). 5.1 to stereo downmix levels are adjusted automatically. Click OK button. Select target file format, sample rate, bit depth. Select target directory Look up eac3to. It's a command-line utility that comes bundled with things like StaxRip. Speaking of StaxRip, it's got plenty of issues of its own, but I'm most familiar with it because I wanted a GUI for AviSynth, and a utility where all the various encoders (x264, x265, etc) were uncoupled from the main binary as separate EXEs (my biggest problem with Handbrake)
Download here the latest libFLAC version (move libFLAC_dynamic.dll to eac3to folder and rename it to libFLAC.dll). If the original audio is mono or stereo, FLAC is preferred. For more channels, you have to use DTS or AC3 (for compatibility reasons). For personal encodes, do whatever you like, I know FLAC is very popular The two ways I have found until now are: to downmix the audio stream with an external utility (like eac3to at least on Windows), but the quality is not always good enough LAV Filters downmix always seems to use both Surround speakers (left and right) when playing back any of the Side/Back speaker channels from the 7.1 source. For example, when playing the Right Side speaker channel audio, this audio is piped to both Surround speakers in my setup, with a larger SPL from the Right surround and a lower SPL from the. Mono and stereo modes are also supported. AC-3 supports audio sample-rates up to 48kHz. Batman Returns was the first film to use Dolby Digital technology when it premiered in theaters in Summer 1992. The LaserDisc version of Clear and Present Danger featured the first Home theater Dolby Digital mix in 1995
All in all, ffmpeg is a nice and easy solution if you want to preserve the same number of channels or if you want to downmix to stereo.

EDIT: Additional testing of using 'Downmix to Stereo' shows that I am also able to play the HDDVD's DD+ (eac3). So now I'm confused, I thought that DD+ (especially the HDDVD variant) was pretty much completely unsupported by everything, the only option being to encode to AC3 on the fly This button makes the Stereo Downmix user interface available, and tells the encoder to use the table in the encoded file (see Figure 5-19).

If you could downmix the BD audio to stereo and save it to a lossless format like PCM that would be fantastic. Do you think that the downmixed BD audio would be noticably better than the downmixed dolby digital 5.1 audio though or is the difference likely to be very subtle? Eac3to seems not to recognize them
I recommend taking the new AAC-stereo profile as example and patching it to AC3. Thanks for waiting! p.s. 7.1->5.1 downmix is possible and works, but would produce incorrect results for smaller multi-channel tracks, i.e. 3.0 will be upmixed to 5.1 and that is not what one probably wants Thank you for the help with the channel mapping. I have added the multi audio mix with 5.1b channel mapping. (Rear not side speakers) I confirm that 7.1 channels are not working Since the TV likely only accepts stereo from the HDMI connection anyway, setting the WDTV to output stereo PCM is your best option and should work as the WDTV can downmix all audio codecs to stereo.

I currently re-encode my larger mkvs through Handbrake to make the file size smaller than 4gb so i can transfer them to my android tablet. The problem I'm having is that the voices/speaking channel is not always loud enough to hear through headphones on the train @ Jeremy, Grabbing the DTS core actually defeats the purpose of adding a secondary track for me. Most tvs cannot decode DTS for playback, but they can for AC3 which is why I choose AC3 as the secondary (example being the SageTV HD200 which does not downmix DTS to stereo so connecting the HD200 directly o a tv and trying to play a movie with a DTS track will result in no sound - eac3to video.mkv - ver que pista es el audio trueHD - eac3to video.mkv numerodepista:audio.flac (AAC 5.1 o AC3 5.1, o hacerle un downmix a Stereo), así a bote pronto te podría servir.
