11/19/2022 0 Comments Ac3 dolby digital![]() ![]() Dolby Digital Plus is widely used by streaming and broadcast services to deliver surround sound audio at lower bitrates. In this configuration, the television’s DD+ decoder transfers the soundtrack in Dolby Digital (AC3) format via the optical fiber, after which it can be decoded by the receiver. Dolby Digital Plus (E-AC-3) provides up to twice the efficiency of Dolby Digital while adding new features like 7.1-ch audio, support for descriptive video services, and support for Dolby Atmos (but more on that later). Best case scenario, the TV will generate a PCM soundtrack for 5.1 channels, but the possibility of activating the receiver’s Night Mode (dynamic compression) unique to Dolby audio decoders is lost.Īnother solution is to connect a Dolby Digital+ compatible television to an older A/V receiver using a S/PDIF optical cable. The TV will then downmix the DD+ soundtrack to obtain a PCM stereo soundtrack, and the original, 5- or 7-channel mix will be lost. ![]() Here is a double blind study of it compared to other codecs at 192 kbps and lower (at 44. ![]() If Dolby Atmos metadata is present, your older Dolby Digital receiver will not recognize any of the data and will tell you it is not compatible.

However, as compression rates rise and Dolby Atmos metadata is added, this is becoming less common. Sometimes, the Dolby Digital Plus soundtrack contains a Dolby Digital core. With Dolby Digital Plus, it would be possible to take the same approach, and yet this isn’t always the case. If the receiver doesn’t provide a list containing Dolby TrueHD, then the source transmits the Dolby Digital core. This format encodes Dolby Digital (AC-3) and Dolby Digital Plus (EC-3) audio files that contain multiple audio channels, including 5.1 surround. This on-the-fly extraction is quite simple in practice: the optical player or TV detects the receiver’s audio decoding abilities via its HDMI controller. The built-in Dolby Digital settings in Compressor (in the Create Blu-ray and Create DVD destinations, as well as in the built-in AC-3 and EC-3 audio settings) use the Dolby Digital transcoding format. Is it possible to configure Kodi so that it would automatically transcode E-AC3 audio to AC3 or DTS whenever I would play back a video with E-AC3? Then my Audio receiver would be able to play back 5.1 surround properly (instead of stereo).The Denon AVR-X2600H A/V receiver is compatible with Dolby Digital Plus and Dolby Atmos. If I enable the the “Dolby Digital Plus (E-AC3) capable receiver” in Kodi System Audi Settings and play back a video file with E-AC3 audio, then the audio is just annoying noise - again, as expected. This makes sense as my Audio receiver does not support E-AC3 and as I have disabled the “Dolby Digital Plus (E-AC3) capable receiver” in Kodi System Audi Settings. However, when I attempt to play back a video file with Dolby Digital Plus (aka DD+ or E-AC3) then I only get stereo.

When I play back video files with 5.1 surround audio encoded in Dolby Digital (AC3) or DTS, then passthrough works great and my Audio receiver lights up the respective logo (AC3/DTS) and decodes/plays back respective 5.1 surround perfectly. In addition, under passthrough settings I have enabled the “Dolby Digital (AC3) capable receiver” and “DTS capable receiver” (as this is what my Audio receiver is capable of). In Kodi System Audio Settings the Audio output device is “PI: HDMI” and “Allow passthrough” is enabled. Audio receiver has 5.1 speaker surround and is capable of decoding Dolby Digital (aka DD or AC3) and DTS.Raspberry Pi 2 -(HDMI)-> TV -(Optical Audio)-> Audio receiver.First of all I have to note that I have been using OSMC on my Raspberry PI (and ATV before that) for years and it has been really great - thanks a lot for the effort! Moreover, I would truly appreciate if someone could please help me a bit. ![]()
