I have some Blu-ray audio discs - Rush Moving Pictures for example. I was thinking of running the analogue outputs from my Blu-ray player through my vinyl ripping ADC to get a FLAC copy for on the move but it seams a shame when there’s already hi-res PCM available. Is there a way I can get the PCM stream from HDMI to USB and use Audacity to “record” the input?
Sorry if it’s a blatantly stupid question but I don’t really understand PCM, DSD etc but I know using the DAC in my Blu-ray player followed by the ADC in my vinyl ripper is likely to be less than ideal.
Thanks but this seems to be about ripping the full video and audio rather than ripping the audio into a FLAC.
What I’m thinking - probably wrongly - is that when I play the blu ray, there is a PCM stream being carried out of the player over HDMI. If I could redirect that PCM stream, via USB, to Audacity, I could “record” the stream at 96/24 and then export to FLAC (in other words the same as I do with LPs).
You aren’t going to get a digital copy of the audio by playing or recording it unless you have a digital sound card or converter with an HDMI input.
I would definitely rip the disc - it must have a Linear PCM stream by definition. I have not tried it but this is supposedly free and should retain all the audio streams into an MKV container: http://www.makemkv.com/ .
If necessary you could then open the MKV file in Avidemux ( http://avidemux.sourceforge.net/ ) and extract the audio. You may be able to convert it to FLAC in Avidemux but if not, once you have got a WAV you can convert it to FLAC in Audacity.
If you install FFmpeg ( http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#ffdown ) and drag the MKV into Audacity it might be able to select the correct audio stream from the file - I am not sure about that.
Thanks for the replies and the suggestions. Looks like I’d need to buy a blu ray drive for the puter plus some copy protection software to rip it properly and given I’ve only 3 blu ray audio discs that could work out pricey. I’ll try ripping it from the analogue stream at 96/24 and see what it’s like before I spend any money.
