Does anyone know how to convert a TrueHD file to FLAC? I have the 'Leonard Cohen - Songs from the Road' Blu-ray and I'd like to extract the high resolution multichannel audio and convert to FLAC. AudioMuxer's conversion tool does not recognize the file extracted using 'Another EAC3to GUI' or other EAC3to utilities. If I use AudioMuxer it creates an output file with the extension 'thd+ac3', which I assume is the TrueHD and embetted AC3 track. I tried converting the 'output.thd+ac3' file, using the converter tool, to FLAC and after checking media, it shows: TrueHD-AC3|96000/48000Hz|Variable/640 kbps|6Ch When I click on the Flac button a big red X on the top of the tree listing. Then there's an info icon and it says: Eac3to LOG -> eac3to v3.22 command line: "eac3to.exe" "E:\Music\Leonard Cohen\extracted using AudioMuxer\Output.thd+ac3" "E:\Music\Leonard Cohen\extracted using AudioMuxer\Output.tmp.wav" -progressnumbers ------------------------------------- TrueHD/AC3, 5.1 channels, 96kHz (embedded: AC3, 5.1 channels, 640kbps, 48kHz) Extracting TrueHD stream... Decoding with libav/ffmpeg... Writing WAV... The libav decoder reported error -1 while decoding. <ERROR> Aborted at file position 262144. <ERROR> I've also used MakeMKV to create an MKV file that includes the 1080p h264 video and just the TrueHD audio and this MKV plays fine. I've also been able to play the extracted TrueHD file (without embedded AC3) with VLC (haven't found any other players that will play it). So I think the TrueHD file is not corrupted in any way. Any suggestions??? |

Normally ffmpeg/libav should work correctly on a TrueHD stream. Since you have the blu-ray, maybe try to extract the audio to wav/flac using the eac3to command line, and see what is happening. I'll assume that you have eac3to somewhere on your PC, or download it from and extract it to a folder of your choice. Shift right-click in Explorer on that folder, and choose "open command window here". The command line will look something like "eac3to g: 1) 3:audio.wav", where g: is for example your blu-ray drive, 1) is the first playlist and from that playlist extract the 3rd stream in wav format. Build it up step by step. First "eac3to <your blu-ray drive>", then observe the playlists that are on the blu-ray, the one with the longest duration is normally the main playlist, let's say this is "1)". Then type again "eac3to <your blu-ray drive> 1)" and you will get the list of streams that are in that playlist. Assume that "3:" is the one with the truehd+ac3 stream, then type again on the command line "eac3to g: 1) 3:audio.wav" and eac3to will try to decode the stream to wav, or if you put "3:audio.flac" it will decode it to flac. If you still have the error, then eac3to together with the ffmpeg/libav codec is having a problem with your blu-ray. From the changelog it seems that libav has been updated since eac3to version 3.22. Therefore, maybe try as well 3.21 since it is using another libav version. You'll never know. |

Exact Audio Copy can rip directly to flac. EAC is the standard cd ripping tool. |

Hi Pl4yitLOUD, Did you change something in the program that ads a gap between the songs? In the version before it was almost not notice-able and on this version it is almost a second. Is it possible to make it seamless for live recorded conversions ? |
