Note, you should use *.w64 (wave 64) if the files are expected to be larger than 4GB in size. You can save each individual channel as a separate WAV file for some other use.From here, you can continue to use Cubase or Audacity to produce a remastered audio file or ….Cubase can definitely split the channels, though. It may be able to perform Split Channels like Cubase, but you would need to test Audacity to find out whether it can and how. Note, this is the part that I do not know if Audacity supports. It may take a little while to split them all out.When the small panel appears asking how you would like to import, choose Split Channels.File=>Import to input output-file.w64 into Cubase.The larger amount of bits you use for mastering, the more likely you will need to use w64. I’m using 24 bits for my remastering efforts. Also, if you want to master in 32 bit or higher, you can choose the pcm output version that corresponds to the bit size you want to use. If you know your output file will be sized smaller than 4GB, you can use *.wav instead. You’ll want to use *.w64 because of the 4GB max size of standard *.wav files. This will create a 6 channel w64 (wave 64) file. This step demuxes the audio from the full movie container.Įxtract the DTS 5.1 audio to single 6 channel WAV file via FFMpeg using the following:įfmpeg -i ack_4352.dts -acodec pcm_s24le output-file.w64 When completed, you will have a *.dts or *.ac3 file as output.Choose ‘Browse’ if you want to place the output file somewhere other than where the app has chosen.Once the file is loaded, uncheck all other streams except the audio stream (DTS or AC3).Load the *.m2ts, *.vob, *.mkv, etc file into TSMuxer Gui using File=>Open.Cubase 5 (or newer) or possibly AudacityĮxtract the DTS/AC3 stream from video container using TSMuxer Gui.This technique may or may not work for 7.1 (8 channel) audio. These don’t require Cubase.įor those of us who are hobbiest home audio engineers, here’s a tip that might come in handy when trying to extract 5.1 (6 channel) audio from DTS/AC3 to individual WAV (or more specifically, WAV 64) files.
