Hello, this is the final script line, and it works perfectly. $shell = shell_exec("$ffmpeg_b -i $audio_file_full_path -map 0:a:0 -af highpass=50,loudnorm=I=-16 -map_metadata -1 -metadata Artist='Agency - VISIT HTTPS://WWW.agency.EU' -metadata Title='Title' -metadata Publisher='agency' -metadata Language=italian -b:a ".$convert_speed."k $audio_output_mp3 2>&1");
Now, I would like to insert an album artwork in the mp3. Is it possible? Thanks. S.
