SoX on 64-bit Windows 7 laptop

Question

I am not able to start the program. I understand i have to use it as a prompt command to open but what do i need to write down there in order to work? This is what i type in cmd and select it and typed in sox.exe infile.wav outfile.mp3 or only sox.exe but it is not recognised as a program on my laptop. Can anyone please help?

Answer 1

SoX.exe is an installer. You want to double-click the .exe file, install it, and then perform whatever commands you want by typing, for example, sox infile.wav outfile.mp3 in cmd. (source)

Edit: Nevermind! Sox installs itself in the Programs File folder (C:\Program Files\sox-[version] on my computer), and as a desktop shortcut, and must be run as a .exe file like you said. The easiest way to do this is to click-and drag the sox.exe desktop shortcut into your cmd window, then append your other arguments (infile.wav outfile.mp3 etc). So the whole command would look like "C:\Users\[user]\Desktop\sox.exe.lnk" infile.wav outfile.mp3.

If your installer didn't make a shortcut, navigate to the sox directory, and click-and drag sox.exe into your cmd window, then append arguments. Ex: "C:\Program Files\sox.exe" infile.wav outfile.mp3

Edit: Aaaand as for how to actually use SoX for what you want... SoX does have a pitch-shift command, according to the documentation page:

pitch [−q] shift [segment [search [overlap]]]
Change the audio pitch (but not tempo).
shift gives the pitch shift as positive or negative ‘cents’ (i.e. 100ths of a semitone).

I don't, however, know how to convert semitones and Hz, or actually pretty much anything musical.

Unless you need a commandline solution (like if you want to make a script), it'd probably be easier to use Audacity's Effect > Change Pitch menu, which has Hz options and is really easy to use.
