    Default Bit rate

    When recording sound at 44,100hz/ 24 bit, at what decibel point do you start to loose bits?
    Sorry if this has already been answered.

    sample rate
    bit depth

    yes please do a search as this subject is well covered

    :roll: ??
    you don't loose bits ... at above or below a decibel level

    do the search then ask a new question if you still need to

    You don't lose bits.

    If you are recording in 24-bit mode, that is what you are going to have. Well, it's like 20 and some change really. But, you will have 24-bit representation of the signal sampled at 44,100 times per second.

    it was my understanding that you loose 1 bit per every 0.6db under 0.0 like if you recorded a signal that averaged at -1.2 the bit depth for that sound would be 22bit.

    maybe i didnt understand completely...

    thanks for clearing it up for me. this forum always seems to help.

    don't think of it that way

    not worth the brain space
    just use the 24 bit headroom sensibly and convert to 16 when you need to
    there is lots more worth worrying about than the intricacies of the math

    ONe bit will give you approximately 6 dB of dynamic range. So, for 16 bit recordings, that's about 96 dB, and for 24 bit, that's 144.

    Those are big numbers.

    Clear and consise, Mr. French(Nice to see you!).

    Does this mean that if I do all my work at 32 bit(Internally) that to somehow "squash/loose", whatever, any "necessary" dynamic range in a piece I plan to eventually use at, say 16/44.1, I'll really have to work at it?

    32 and 48 internal math is about calculations for the mixer and plugs
    please don't worry about it

    as Dave said you have up to 144dB dynamic range to work with at the front door and if you capture adequately you will need to squash to get to typical CD mastered variations anyway

    don't worry about it
    to lose a bit or 2,
    and if you did it's just not an issue for typical pop/modern music
    :roll:
    ... just maybe if you were in the Orchestral World of direct to two track ...
    do
    look for typical analog clipping diring capture and digital clipping during mix
    and all along the way let the digital headroom bounce between -20dBFS and say -3dBFS and let the equipment do it's job

    even if you did have ONE track with a digital clip ... or an -0.01dBFS
    and you can't hear a problem ... let it go IF it is a good take.

    it's all good
