Linux Command Line – Set Audio Balance from Command Line

audiocommand linelinux

I'd like to set audio balance from command line (linux), I'v looked at 'aumix' (and googled around) but it seems it does not have an option… can you suggest any method?

Best Answer

With amixer, you can set the volumes of the left and right ALSA channels. For example,

amixer sset Master 80%,20%

will shift the balance toward the left.

Linux – Split PDF document from command line in Linux

I find pdfseparate very convenient to split ranges into individual pages. This command would extract pages 1 - 5 of input.pdf into files named output-page1.pdf, output-page2.pdf, ...

pdfseparate -f 1 -l 5 input.pdf output-page%d.pdf

If you want to recombine them into page ranges, for example pages 1-3 in one document and pages 4-5 in another, you can use the companion program, pdfunite, as follows:

pdfunite output-page1.pdf output-page2.pdf output-page3.pdf final-pages1-3.pdf
pdfunite output-page4.pdf output-page5.pdf final-pages4-5.pdf

I believe theese tools are part of poppler and may already be installed on your system.
