eac3to is a freeware application that is capable of converting E-AC3, TrueHD, PCM and DTS-HD audio tracks to AC3, DTS or FLAC.
- Dolby Digital Plus, also known as Enhanced AC-3 (and commonly abbreviated as DD+ or E-AC-3, or EC-3) is a digital audio compression scheme developed by Dolby Labs for transport and storage of multi-channel digital audio.
- Hi, I'm looking for a few days but the i have a problem. I'm running TVHeadEnd Server V4.1 on OSMC=:smile: it work well with channel AAC 2.0, ok with channel AC3 but the channel with EAC3 don't work. The mkv file with DTS or DD/AC3 are Ok. With EAC3 channel i have black screen. The AVR is a pioneer VSX 824.
- AC3 (Dolby Digital) is widely used in HDTV broadcast, DVDs, Blu-ray Discs and game consoles. As part of the MPEG-4 standard, AAC codec makes small digital audio files so that it can store a larger amount of audio files using less space while preserving sound quality. Normally, AAC can produce frequency ranges from 8 to 96 kilohertz.
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.
E-AC-3 is superior in keeping fidelity to the original audio source than AC3, and clearly has a better audio quality. AC-3: 1.0 to 5.1. E-AC-3: 1.0 to 7.1 (and is going to achieve 15.1 in the future) With more audio channels, E-AC-3 is able to make people feel more immersive. AC3 sounds really poor to my ears but is more compatible and consumes less disk space Known the technical differences between then, I still wonder if DTS is a trend for the near future or AC3 will stand long popular. I installed AC-3 audio codec on my system but I found no differences at all.
You can use eac3to to apply filters, apply an AC-3 bit rate, down-convert, down-mix and change the quality and channels of AC3 files. It also supports channel mapping, TrueHD, DTS-HD and FLAC files.
Third party codecs for saving files in different formats might be required.
The bottom line: eac3to is a capable and useful program for converting high definition audio to other formats that can be played on portable devices or on a PC.

AAC VS AC3: History
Developed with the cooperation of companies including AT&T Bell Laboratories, Fraunhofer IIS, Dolby Laboratories, Sony Corporation and Nokia, AAC, was claimed as an international standard by the Moving Picture Experts Group in April 1997.
AC3 was originally named Dolby Stereo Digital until 1994. In the early 1997, Dolby Laboratories officially changed 'Dolby AC-3 surround sound' to 'Dolby Surround Digital' which we often called as Dolby Digital.
AC3(Dolby Digital) VS AAC: Compatibility
So far, AAC is the default audio format for YouTube, iPhone, iPod, iPad, Nintendo DSi/3DS, iTunes, DivX Plus Web Player and PlayStation 3. It is well supported by PlayStation Vita, Wii (with the Photo Channel 1.1 update installed), Sony Walkman MP3 series and later, Sony Ericsson; Nokia, Android, BlackBerry, and webOS-based mobile phones. And a majority of in-dash car audio system manufacturers will adopt AAC.

Ac3 Vs Eac3 Dual
As part of the MPEG-4 standard, AAC codec makes small digital audio files so that it can store a larger amount of audio files using less space while preserving sound quality. Normally, AAC can produce frequency ranges from 8 to 96 kilohertz. While AC3 provides a total bit rate of 384 kilobits per second. Its sample rates can up to 48 kilohertz. And if you want to enjoy the full effect of the AC3 track, you should choose an amplified theater system which supports Dolby Digital.

Ac3 Vs Eac3 2
In a conclusion, AAC is a more advanced lossy audio format comparing with AC3. It will produce better audio quality than AC3 with the same bitrate, especially on low bitrates. The main advantage of using AC3 is for backward compatibility on older Dolby Digital equipments.
