If no other processing is required Yes, the only thing it should do when converting form 16 to 24 bit is add 8 zeroes, but SOX works internally at 32 bit, so if any DSP is involved, the new values will have 32 bit precision, when writing the output SOX will truncate at the most significant bytes required by the user. So is really depending on what you ask SOX to do. To be sure, try to apply i.e. some gain reduction and you 'll see what happen. By the way, other 8 zeroes are added from squeezelite, just becouse your sound card require 32_L£ format. ____________________________________________________________ SB+, Klimo Merlino + Kent Gold, Monitor Audio Studio 20 Gold SE+, Klimo reference and DIS Interconnect. ------------------------------------------------------------------------ marcoc1712's Profile: http://forums.slimdevices.com/member.php?userid=34842 View this thread: http://forums.slimdevices.com/showthread.php?t=105309
