Multiple wavs to Blu-ray PCM

odin24 · 17th April 2009, 23:30

I'm trying to save disc space by taking a 7.1 PCM file and make a 5.1 file. I heard SoX can take multiple wavs and make a PCM file. However I'm having a hard time understanding how to go about this.

I am familiar with command line, but trying to read through the readme in confusing. Could someone give an example of how the cmd line should look, or suggest another app that can do this.

Thanks.

EDIT: I already have the multiple wavs.

I know you already have the individual wavs but if you take a step back to the original 7.1 file you can use eac3to to downmix to 5.1:

eac3to input.pcm output.pcm -down6

I can't remember if the output extension should be pcm or lpcm, and you might have to specify the input pcm details too. It's all in the eac3to help and pretty straightforward though.

Holy crap!!! I didn't even think about that. Thanks. I knew about the -down2, I didn't even realize there was a -down6 switch.

Thanks again.

assuming you want to remux with tsmuxer, you have to choose lpcm as output and run it through "pcm2tsmu" (little tool to make a pcm file accepted by tsmuxer)
you could also try eac3to "wav64" output and import that into tsmuxer, you wouldn´t need the pcm2tsmu step, this feature is very new and i didn´t test it so far, so no guarantee there, the 1st method definitely works

Thanks, I'm familiar with pcm2tsmu. I'm all set now.
