HDMI audio capture/ separator card?
The recent post about audio separation of Blu-ray has me interested in the
process also. I too would like to separate the audio into the 8 separate channels in the most lossless way possible. Currently, I do this with a Samsung Blu-ray player that has the built in decoder, but the output is analog and then we have to go from A to D when capturing into the PC. I suspect this is somewhat lossy and also depends on converter quality. There doesn't seem to be a program that will do it which I wonder about since one could separate DVD into separate audio channels with such a program, so now I'm looking at a diffferent approach: separation of audio channels from HDMI. Is there an audio card I could install of decent quality that would allow me to separate and capture the 8 audio channels via the HDMI cable of the Blu ray player? I would prefer to be able to save each channel as a wav file if possible. Is there any advantage to doing this over using my current system (would it be less lossy, is AD-DA conversion involved, etc)? Thanks in advance, Bill |

Thanks in advance, Bill I think Ensemble might make a DE-mux that take HDMI input. Generally HDMI is a consumer format, what you'll want is an HD-SDI input that will output all 4 channels of AES and Demuxed video. Ensemble, Mirranda, Evertz, and Grass Valley all make this box. I think the Ensemble Bright Eye is the cheapest way to go. Why wouldn't you just import the whole Blu-Ray file then strip the audio from it? There must be a program that does that. |

And it is great fun when a projector in a small lecture hall cuts out because the hdmi-source thinks the projector may be doing something that infringes copyright because of the cable length. It is also great fun - laughing all the way to the bank - for those that make the compensation box to put on the projector end of the cabling to prevent it from happening. Kinda like the ploy of changing the user interface so as to keep the it-support staff busy and necessary, that however is something I am a perfectly happy microserf with ... O;-) geoff Kind regards Peter Larsen |

There are programs out there that will strip blu-ray discs, as long as they aren't protected. All that XD-Cam stuff records to Blu-ray, there should be something out there that will deal with it in post. |

All that XD-Cam stuff records to Blu-ray, there should be something out there that will deal with it in post. I used to have a scanner-printer that refused to copy and print mucis scores. I found out that if I put something else in for the pre scan, and then switched to the music score for the final scan, I could get it to copy and print the music. When manufacrurers take it upon themselves to police me, It makes me angry, and I will go to great lengths to override them. |

Thanks in advance, Bill take a look to the "De-embedders" Kramer electronics make the FC-46, but there are a lot of better brands out there. With this you can "demux" the audio in SPDIF format then acquire it with most digital soundcards. alex |
