in 32 bit float mode it does in fact 'declip' files over 0dBFS when volume is adjusted in an audio editorAny way we can get you to test in 32 bit float the input to the SD card. Then export the file and see if it really can't be clipped. Not that I expect it will improve the noise situation or get close to 25 bit dynamic range. Just wondering if it will scale the various input levels so it works not to clip any signal as claimed. That is the reason anyone who purchases this recorder would choose it over another Zoom model or other brand recorder.
however any signal over +4 dBU will still be ruined
i havent ever used the limiters
at the end of the day per my tests the 32 bit offers no audible benefit over 24 bit, even if levels were set low enough to allow for headroom. if you know your gear its not too difficult to set your levels where it will clip the input before it clips @ 0dBFS
