Eac3 To Ac3 Converter
Claribel Szwaja
EAC3 is the abbreviation of Enhanced AC-3, which is the advanced version of AC3 and many devices and software do not support EAC3 audio codec. So sometimes you'll run into no sound issue while playing some video files with EAC3 codec.
Q: I've got an MKV with EAC3 audio codec that won't play on my receiver. Can I convert the audio of this file with a do-it-all program that will demux and remux the video with AC3 instead? I have AVC Pro, which does a good job of converting the audio, but it will downmix from 5.1 (or even 7.1) to stereo.
A: EAC3, also known as Enhanced AC-3 or Dolby Digital Plus, is the successor to Dolby Digital (AC-3). EAC3 is a digital audio compression format typically found in MKV, M2TS or other multimedia container formats. However, many media players and portable devices do not support EAC3 decoding. As a result, you may find that your video files are voiceless while playing. To solve this problem, we need to convert Dolby Digital Plus to Dolby Digital. And this article will show you how to convert EAC3 to AC3 and keep 5.1 channel at the same time.
There are quite a lot of batch video converters available, which enable you to convert EAC3 track to AC3 in a video. But most of them will downmix original 5.1 channel to stereo and even lead to terrible quality loss. Given this, HD Video Converter Factory Pro is highly recommended as a professional EAC3 to AC3 converter that allows you to convert EAC3 audio codec to AC3 with original quality and keep the 5.1 surround audio remained. Now, follow the tutorial to change EAC3 into AC3.
Launch HD Video Converter Factory Pro and open "Converter" module, then add video files with EAC3 audio track into the main interface by pressing the "Add Files" button or just drag and drop the files into the converter interface.
Click the Format Profile on the right side to open the full list of 500+ presets. Then choose a needed format under the "Video" tab, such as MP4 or MKV. Press the "Parameter settings" button and choose AC3 codec in the drop-down list of audio "Encoder" section so you can change audio format in video. Choose "6 Channels" in the drop-down list of "Channels" to keep 5.1 audio. Then, click "OK" to save changes.
Specify an output folder by clicking the inverted triangle icon at the bottom of the main interface. Then click on the "Run" button to start to convert EAC3 audio codec to AC3.Now, the problem of " playing video with no sound" should be fixed.
Besides converting EAC3 codec to AC3, HD Video Converter Factory Pro, as a professional video converter, enables you to convert video audio files to 500+ formats and devices within 3 steps: Import files > Select format > Convert and Export. You can convert MP4 to MKV, MKV to MP4, MKV to AVI and so forth. What's more, you can adjust encoder and bit rate of both audio and video files on the Parameter settings window.
WonderFox DVD Ripper Pro, a reliable and professional DVD ripper, enables you to rip audio files from DVDs at ease. You can convert the ripped audio files to MP3, WAV, FLAC, ALAC and other formats for convenient playback on various portable devices.
I have a number of video files stored on my Synology of which the audio doesn't play on when opening them with DS File. This is because DS File does not support eac3. I would like to convert those files to aac using ffmpeg, but when doing so, all audio is lost.
Another tool I used says it supports Dolby Digital Plus (which my audio track is btw) but when I want to import my eac3 file it says that it's not supported. By simply changing the extension to .ac3 it works flawlessly.
Dolby Digital Plus bitstreams are not directly backward compatible with legacy Dolby Digital decoders. However, Dolby Digital Plus is a functional superset of Dolby Digital, and decoders include a mandatory component that directly converts (without decoding and re-encoding) the Dolby Digital Plus bitstream to a Dolby Digital bitstream (operating at 640 kbit/s) for carriage via legacy S/PDIF connections (including S/PDIF over HDMI) to external decoders (e.g. AVRs, etc.).
The VLC media player can also convert different video and audio formats. Well, if you have compatibility issues such as the audio format eac3 is not supported, you can convert it to MP3 or any other format. Here are the steps to fix the eac3 audio support video player problem:
To make sure you download and install the right custom codecs, you should check the version of your MX player that is running in your media player. After seeing the version, then take the following steps to choose and download the custom codec:
This is another quick solution to fix the MX Player eac3 audio not supported error. You see, you can encode MX player eac3 audio not supported to more compatible formats, such as MP3 and MP4. All you need to do is to use any professional video or audio converter.
You can find some free video or audio converters, but you need to choose the best one that is available. In this case, you can convert video and audio files to digital formats in a straightforward way to fix audio format eac3 not supported MX Player.
If the methods introduced above don't work, another great option to fix the eac3 not supported error is to use a different audio player that supports eac3 audio format, such as VLC media player.
Sometimes, video or audio files are lost or deleted from your device, making it impossible to hear audio while playing. In such cases, you see a flashing message saying the MX Player eac3 audio format is not supported. You can use the solutions discussed above to fix audio eac3 not supported, but if they all fail, you need to utilize a professional audio recovery tool.
However, you can only recover lost or deleted audio files if you have not used the drive or storage media. Remember that playing the audio files on the faulty media might overwrite the original data. This means the audio files can be lost beyond recovery.
Recoverit can restore lost or deleted EAC3 audio files of any format, such as MP3, WAV, AU, AFF, MP4, and AVI. This audio recovery tool with an intuitive and user-friendly interface can recover lost or deleted files like audio files from memory cards, SD cards, hard drives, and USB flash drives. Simply put, the Recoverit audio recovery tool supports corruption in the sound section of the video files, audio and video sync problems, and many more.
Above all, this software works well in all audio file loss situations, whether you see this audio format eac3 is not supported, deleted, audio file transfer faults, or virus infection. It recovers lost or deleted files on both Windows and Mac computers or any Android device and allows you to save them at your desired destination on external media or drive. You can easily get the audio files by taking the following steps.
After completion, you will view the deleted files listed on the left panel of your screen. Recoverit allows you to select multiple audio files simultaneously and preview all of them. Best of all, there is no limitation on the size of audio files to repair, meaning you can repair multiple corrupt audio files.
Lastly, click on the Recover button to recover your lost or deleted audio files. Note that it might take a while to recover the audio files. However, you should always consider saving the recovered files in another location.
As explained earlier, because of the patent licensing issues, you might encounter errors, such as audio format eac3 is not supported in the MX player. The good news is that you can do the following if the video has audio eac3 not supported MX Player:
MX player is undoubtedly one of the best video players for android devices with plenty of features. But with the removal of its audio codec supports like DTS, AC3, and MLP due to some licensing problems, you may notice an error message that states the eac3 audio format is not supported in MX Player. Unfortunately, sound problems can make your experience quite annoying. Thus, you need to understand some basic knowledge of EAC 3 files.
EAC3 which is also called the enhanced AC-3 is a digital audio compression format that was developed by Dolby Labs to store and transport digital audio. It succeeded AC-3 which is another format developed by the same company. The coming of EAC3 saw various improvements, such as an increase in channel count and support for a wider range of data rates.

With this tool, Windows and Mac computer users can recover audio files safely and without a problem. Having gone through such a bad experience, you can rest assured that any lost or deleted files will be recovered as quickly as possible.
The thing is the output quality is really bad. It sounds extremely compressed, judging by my ear it sounds like about 32kbps.My theory is that the output is for some reason 192k divided by 6 channels, each channel being 32kbps and the whole audio track is 192k overall. To my knowledge, that's not how its supposed to work and it should sound like the equivalent of 192k for each channel in one bitstream.
Edit: Something I just realized on this and tested is that the audio quality that I hear when using ffmpeg to encode to ac3 and then to encode to eac3 is the same. But as eac3 is almost twice as efficient as ac3, I would expect the eac3 encode to be much higher quality and sound less compressed. Case in point is that the Telestream Vantage encode is much higher quality than an ac3 at the same bitrate. Is this a fault of of the ffmpeg encoder that is used for eac3?
Your issue was the fact you set total average bit rate to 192kbps, not per channel. Presuming ffmpeg's default AC-3 encoder, if you simply set the sample rate to 48kbps (which you did in your example above), you'd be encoding at 1,536kbps for all channels. That is because the only bit depth that codec supports is 32 bits per sample.
