When we have to extract the audio from a compressed video file in MPEG format, the process we must do is called demultiplexing. The different parts or channels of which a multimedia file consists are separated, and saved separately. BatchDemux is a tool that serves precisely to carry out this process, and that offers its greatest utility when extracting and saving separately the sound of an MPEG file, and also even the VOB files of the DVDs.
Batch means in massive English, or in batches, and that is the other important feature of the BatchDemux program. We can open several files simultaneously in BatchDemux and tell you to process them all together, one after the other. Ideal to execute large operations without the need to walk adding MPEG files one by one.
Basically, BatchDemux is a graphical interface for the mpgtx and bbdemux commands. Instead of having to use them through the DOS console, we use this BatchDemux program and can operate with them much more easily and without worrying about knowing how their parameters are used or in what order. In fact, in the program's own interface we can select which of these two engines to use. For the rest, we will find a very simple window with few options beyond indicating which multimedia files we want to demultiplex.
You can free download BatchDemux 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
