“I have a bunch of Blu-ray files that have TrueHD, and I want to retain the TrueHD audio. I typically use Handbrake to compress the video files, but I have held off on the TruedHD audio contents since it doesn’t pass them through. I tried a few other encoders Megui, Staxrip. To be honest I struggle and couldn’t get it to pass TrueHD through as I don’t fully get them. Basically, how can I compress those videos and retain the TrueHD audio?”

Here I am going to introduce a Dolby TrueHD encoder for you to encode TrueHD audio. Check the post out to retain Dolby TrueHD audio of video files.

Part 1: Introduction to Dolby TrueHD Audio

Dolby TrueHD is an advanced lossless multi-channel audio codec developed by Dolby Laboratorieswhich is intended primarily for high-definition home-entertainment equipment such as Blu-ray Disc and HD DVD. It is the successor to the AC-3 Dolby Digital surround sound codec which was used as the audio standard for DVD discs. In this application, Dolby TrueHD competes with DTS-HD Master Audio, another lossless codec from DTS.

In the Blu-ray specification, Dolby TrueHD is an optional codec. Dolby TrueHD audiotracks may carry up to 24 bit audio in up to 8 discrete audio channels at 96 kHz or up to 6 channels (5.1 surround) at 192 kHz. The maximum encoded bitrate is 18 Mbit/s (the same as the uncompressed rate). Since TrueHD is an optional codec, a separate (primary) AC-3 audiotrack must be present on Blu-ray discs that contain a TrueHD track.

In the HD DVD format, Dolby TrueHD was a mandatory codec. The HD DVD specification permitted the sole (primary) audiotrack of a movie to be encoded in Dolby TrueHD, and the specification requires support for up to 2 channel (stereo) decoding. In practice all HD DVD players decoded multichannel (5.1) programming, and of the few HD DVD movies to be encoded with Dolby TrueHD audiotracks, all were multichannel.
