I'm learning how to use
sox and i encountered this explanation:
We can also use sox to convert a raw file to another format. In this case, we have to supply some information about the raw file:
sox -r 44100 -s -w foo.raw foo.wav
The three flags preceding the input file name tell sox that the input file has a sampling rate of 44,100 samples per second, that the data is signed, and that each sample consists of a two byte word ...
What signed means in this context? The paragraph above is from here.
