downmix to dolby 5.1

Post by rcrh »

Description of problem or question:
my audio system doesn't handle DTS so I downmix my audio to Dolby Digital 5.1. If I have a choice of DTS7.1 HD-MA or DTS5.1 should I start with the master audio and let handbrake drop the two extra channels?

Steps to reproduce the problem (If Applicable):
n/a

HandBrake version (e.g., 1.0.0):
1.2.2

Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Windows 10 Creators Update

HandBrake Activity Log ***required*** (see How-to get an activity log)
n/a

I've been using the MA-HD audio even though it has extra tracks.
Thanks for any guidance anyone has.

Code: Select all

Doesn't really matter - the source is the lossy core of the DTS HD-MA either way.

The nightly build can decode the HD extensions, however.

Hello Rodeo, has the ability to decode the HD extension been released in an official build? I have seen older posts saying that Handbrake cannot decode DTS-HD MA tracks, and it uses only the core for audio encodes. Is that still true?

Yes, pretty sure 1.3 and later now have DTS-HD decode support; possibly even earlier (1.2.x) but not sure.

Hi Rodeo, thanks. Do you know which decoder Handbrake uses to read the DTS-HD MA tracks to make the resulting encodes (i.e. AAC)?
