Of course there are very light differences between decoders but jruggle (ffmpeg developer in AC3 area) minimize the problem. eac3to uses libav to decode AC3 to 64 bits float (the best resolution), and libav was actualized in eac3to v3.27 (the test was made with 3.24). I'm trust in the AC3 expert (jruggle) about that. BTW, if you prefer use a class "A" free decoder liba52 you can use BeHappy with NicAudio to decode AC3.

There are light differences (like with AC3 in precedents posts). ArcSoft is a "certified" decoder, libav a free decoder. It's your choice.

I am having a problem trying trying to decode a TrueHD to anything, wavs, w64, wav or flac. I get the following log:
bitstream parsing for track 2 failed demuxing this track may still produce correct results - or not. This audio conversion is not supported. The eac3to info says: 2: TrueHD, English, 7.1 channels, 48KHz The mediainfo says: Audio #1 ID : 2 Format : TrueHD Codec ID : A_TRUEHD Duration : 2h 2mn Bit rate mode : Variable Maximum bit rate : 7 719 Kbps Channel(s) : 8 channels Channel positions : Front: L C R, Side: L R, Back: L R, LFE Sampling rate : 48.0 KHz Compression mode : Lossless Language : English Default : Yes Forced : No I have demuxed using mkvtoolnix and changed the extension to .ac3, .thd+ac3 and .truehd and when I try to look at it with eac3to it just says The format of the source file could not be detected. tsmuxer won't recognize it and vidcoder (handbrake) doesn't even acknowledge it is there. Could this be some new form of protection from Dolby. Do I need to update a codec or something. Could it by Dolby atmos - is there a decoder for that?

*Edit: My apologies, due to bad searching I didn't find the posts about using ffmpeg.
Is there a way to determine if the above track I was talking about is Dolby Atmos. Is that what the A in A_TrueHD stands for? If Yes, then: I just want to be certain. If I have an .mkv file or a Bluray folder with a 5.1 or 7.1 TrueHD (atmos) track and use the following command, it will output the lossless TrueHD extracted audio in a flac file with proper channel mapping? ffmpeg -i "my file or folder" -map 0:1 "extracted_audio.flac" Last edited by bmcelvan; 25th February 2015 at 18:15. |

The case of the movie should tell you if it has Dolby Atmos.

I don't know what happens with a folder input. For questions about ffmpeg syntax please use this thread: ffmpeg syntax

I tried replacing the avcodec-54.dll and avutil-52.dll files with newer versions from the latest version of Zeranoe FFmpeg, but eac3to gives me an error that the dll is missing.
What am I doing wrong? As a side question; is there any other tool/method for converting DTS or dolby audio besides eac3to? |

You can certainly convert DVD Video compatible dts or Dolby Digital audio with other tools, like BeHappy or MeGUI, maybe TEncoder. HD audio from Blu-rays is probably not widely supported though.

Try TAudioConverter (ffmpeg) Or AviSynth based BeHappy/MeGUI like LigH say.

Bug? DTS-MA 1.0ch (mono!) -> WAV/FLAC broken
Hello!
Config: Code:
C:\TMP>C:\eac3to\eac3to.exe -test eac3to (v3.27) is up to date Nero Audio Decoder (Nero 6 or older) doesn't seem to be installed ... ArcSoft DTS Decoder (1.1.0.8) works fine Sonic Audio Decoder (3.27.0.0) doesn't seem to be installed 10MB snippet: http://www.file-upload.net/download-...est.dtsma.html Code:
C:\TMP>C:\eac3to\eac3to.exe test.dtsma DTS Master Audio, 1.0 channels, 24 bits, 48kHz (core: DTS, 1.0 channels, 24 bits, 768kbps, 48kHz) Only way to handle this is extracting the DTS-core and convert the DTS afterwords. However, MPC-HC is able to play the original .dtsma file. So the ArcSoft DTS Decoder does work for this file? Any hints on what to do?
