    My m-powered protools has 12db before clipping on the faders, i know the HD version has like 20db or so. What does logic have?

    It depends on your interface (AD/DA converters) and what bit rate you are recording at. The DAW itself doesn't really affect that aspect.

    Your question doesn't make sense. Headroom above what?

    ITB 32-bit float and 24 bit recordings have almost unlimited headroom.
    As Jack said: it is more the AD/DA converter levels that need to be watched.

    24 bit recordings do NOT have 'infinite headroom': they clip at 0dBFS just like 16 bit files, and regardless of the interface or the DAW software.

    I read the question again: still doesn't make any sense.

    Edited my nonsense out.. :-(

    IIRs is right... I was a bit confused by the ?question?
    It might be better to wait till he tells us what he actually wants to know.

    This is still not correct. Within the DAW (assuming a native DAW) mixing will use 32 or 64 bit floats, so you do have lots of headroom above full scale.

    I don't think any DAWs mix using 24 bit integers these days. But if they did they would clip at 0dBFS, which is the same level for 16 or for 24 bit audio.

    The advantage of 24 bit over 16 bit is the extra resolution at the other end of the scale.

    I think the OP is asking how much marker/reading scale is listed above 0 on the faders themselves...
    Logic doesn't show a gradient marker for levels on their faders...seems like that should be programmable though.
    The term "headroom" might not be what he was talking about???
    Maybe thepilgrimdream can explain his question in more detail????
