ok, but the sample rate information is in :
Stream #0:0: Audio: mp3, 48000 Hz, stereo, fltp, 320 kb/s

What happens is that I don't know which command I use to compare only the
sample rate that is in the audio stream and manage to filter
the audio with only 48000 khz to another folder. That is, what command do I
use to read only the sample rate 48000 khz and be able to select it??

well, use some scripting labuage like PHP, call ffmpeg and decide by if(strpos($ffmpeg_output, ', 48000 Hz,') !== FALSE)

and do yourself a favor and forget the stupid idea "copy them to another folder where I will change from
48000 khz to 44100 khz"

one simply don't encode a lossy codec again
