View Full Version : Problem extracting audio HD-DVD Eagles Farwell 1 tour

Hi,

I want to use the audio of the HD-DVD Eagles Farwell tour. Disk is not AACS encrypted, so rip is easy.

There are 2 audio streams: DTS-HD and one LPCM stream. I tried several demuxers, like Evodemux, but there is a problem getting the LPCM track converted into wav or flac.

The first problem is when I look at the Evodemux info: it says the LPCM stream is 48k/16b/2ch, but the bitrate is 2304 kbps, looks more like 48k/24b/2ch.

After demux, the LPCM track is in a file with MPA extension, I try to convert to wave with EAC3to. When selecting 24 bits, EAC3to refuses to process the file, even with the -override option. When selecting 16 bits, the file processes (says 48k sample rate, looks good), but the resulting file sounds like the wrong sample rate (music plays too slow) and with some static.

I also tried to convert the MPA file with flac 1.2.1b with the --force-raw-format option, but the resulting flac file crashes winamp on playback and sounds only loud static when converted to wave.

When I playback the original EVO file on PowerDVD, it does say the LPCM track is 2.0 / 48k and plays back normally, so nothing wrong with the EVO files.

Any idea?

You should post this in the eac3to thread.

Set the lpcm file extension to .pcm (not .mpa) and try

eac3to input.pcm output.flac

without specifing any parameters.

Thanks for responding!

I was not sure where to post as problem can also be in the demux process.


Tried your suggestion, but eac3to refuses to work with the file. Here is the output:

E:\cod>eac3to concert_pt1.pcm concert_pt1.flac
This might be a RAW/PCM file. Trying to figure out the details.
This will probably take a while. Please be patient...
Was not able to figure out all parameters of this RAW/PCM file.
Please specify channel, bitdepth and endian parameters via command line.
The format of the source file could not be detected.
