TrueHD is another commonly used Blu-ray audio format, however in this case it's a single lossless audio stream so tends to be slightly smaller than DTS-HD MA, however if you have a single TrueHD audio track for your video then all equipment must be capable of decoding it.

KODI DTS DECODER FULL
The advantage of this type of encoding scheme is that equipment that can't decode the full DTS-HD MA will still be able to recognise the lossy Core DTS 5.1 stream.
KODI DTS DECODER RAR
These formats differ from the Lossy formats in that they don't chuck data away but instead compressed the PCM data with highly sophisticated algorithms that allow the original audio to be reconstructed (hence lossless), this is very similar in principle to the way zip & rar works on documents in that the original source can always be reconstructed.įor the lossless formats such as DTS=HD MA, although the audio data is compressed the they still require the same number of PCM channels to be available as they are trying to pass unlike the lossy formats so 7.1 channel DTS-HD MA still requires 7.1 PCM channels.ĭTS High Definition Master Audio (DTS-HD MA) is the commonly used on Blu-ray and uses a Core plus Extension encoding scheme where: Take SPDIF as an example, this type of audio path can only handle a maximum of 2 PCM channels, however a format such as DTS can still be passed as 5.1 channels because once encoded into DTS the data is so much smaller than what is required for 2 PCM channels. When audio is in a lossy format it is so much smaller than the original uncompressed PCM data that it's still possible to send 5.1 channels even when "Number of channels" is 2.0. Examples of lossy formats:ġ.2.1.1 Why 5.1 is possible when number of channels is 2.0? These formats take the PCM audio data and use encoding algorithms to throw away (hence term lossy) audio information that the human ear cannot hear in order to save space. There are two types of encoded formats, these are lossy and lossless. Since PCM is uncompressed audio this is a frequently used way of expressing the raw bandwidth for a particular audio path, thus when you see the "Number of channels" setting in Kodi this is the number of PCM channels. When number of channels is referred to, it will nearly always be the number of PCM channels that is meant. All manipulation of audio in the digital domain is always done on audio in the PCM format, therefore functions in Kodi such as volume control can only be done on PCM data, therefore if audio is in one of the Encoded Formats Kodi must decode the audio to PCM in order to manipulate it for volume control. When analog audio is converted into the digital domain the near universal format used is Pulse Code Modulation (PCM).
KODI DTS DECODER HOW TO
This page will help guide you to understanding some basics in audio and how to troubleshoot basic audio issues. To understand how Kodi processes audio you must first have a basic understanding of how audio in the digital domain works.
