      does floating point (32 bit float) mean that you can clip in the digital domain and as long as the mixer faders aren’t clipping it’ll not effect the sound? (I read that somewhere but am not sure how true it is).

        Hope that all makes some sort of sense – gonna stop now cos it got a lot longer than I planned it to be… :sign0020:raaa:lol_crash

        How long did it take you to write that? :bounce_p:

        Thanks to all for the explanations I’ll try figure it out … Eventually xD

          You should of cheated used loads of pictures like I did. 😉

            32 bit float just means the resolution is 32bit and uses floating point representation (in accordance with IEEE 754 ).

            As it’s just a way for computers to represent information, and perform calculations, and doesn’t relate to a physical property of the audio I would suggest that it would have no effect on clipping (which is a physical property of the audio). If it’s clipping in the digital representation then it will be clipping when that representation is converted back into the audio represented…

            A wee while (memory trawling gets more difficult the older you get – especially if your youth was properly mis-spent 😉 )

            I tried, but the single picture there took me about as long to draw as it took to write the text :laugh_at:…:crazy_fre

              I never clip my faders … I ment when running stuff thru vst’s … would it matter if they were all red lining at 32bit if the final faders were not clipping, or have I totaly misunderstood that part of 32 bit floating point?

              See you need to cheet even more and steal pics from google 😛

                Yes it will matter – if you are redlining any part of the signal chain it will distort whether your mixer is digital or analogue. As I say, 32 bit floating point is just a way of representing in numbers the audio you are working with. If you redline the mixer channel with a VST instrument you are driving it up to a point where there isn’t enough space at the upper end to represent it properly – the result will be clipped audio and distortion (which can obviously be introduced purposefully for a particular audio effect – if you then ensure the main out channel isn’t overdriven it will sound fine assuming you want that overdriven sound for that particular VST – I would suggest you would be better off using an overdrive effect instead of doing this, but if it gets the sound you want doing it this way then it’s all good :wink:)…

                Normally I would’ve, but I couldn’t find one that showed what I was trying to explain properly :crazy_dru

                  see that’s what i thought, but I read somewhere that 32 bit float has no clipping point when in the digital domain (or something like that)
