It doesn't matter what you set the bit-dept in ACID if your pre-amp (or whatever interface you're using) can't record at 24-bits.
it's still noise.Īlso, make sure your hardware can handle 24-bits. Once you record noise, it doesn't matter how many bits the program uses to process or render it. When you reduce this down to 16-bits of dynamic range in rendering, you're including less noise as a proportion of signal to noise, than if you recorded at 16-bits. So why record at 24-bits when you're going (most likely) to render it to 16-bits or to an MP3 file? Because you'll capture less noise and more signal when you record. Listen to a reverb tail or very quiet passage and compare the difference. Increasing the bit depth to 24-bits can have a noticeable improvement in the quality of your audio, assuming your noise level (hum, electric noise, whatnot) isn't too high to begin with. Where this matters most is on the recording end (once you process it you're working above 24 bits in ACID and when you render it most likely it's to 16 bits), but realize that improving your maximum dynamic range doesn't affect the high end (clipping is still clipping) but the low end. 16 bits = 96db, 24 bits = 144db of dynamic range. I agree with what's been posted, but will add my 2 cents.īits = dynamic range 6db per bit. Set you sample rate to a reasonable working rate. So, set your project bith depth to the best your hardware can support. If you have a really good tool for resampling - Sound Forge - then you can record at 96 or even 192 and then resample a master mix to the sample rate of delivery. If your final goal is 44.1 16 bit, then you should try to max out at 88.2.
Too high and you will use a lot of space. The recording sample rate is another story. Still, with harddrive space as cheap as it is, just record at 24 bit and be happy with the extra zeros. There is also the limitation of the converters you are using. However, even at 24 it is unlikely you have a ambient noise level that will permit you to use all of those bits effectively.
Obviously you should record at the highest bith depth that your hardware permits. With many loops being shipped at 24 bits, and softsynths generating floating point data (which is essentially 25 bit) you will be better served to work at this depth and then dither down to 16 bit when you render.īit depth is more important when recording, but this is a limiting factor of you hardware. The project bit depth will be used as the default rendering bith depth - when the format permits this - but it is not limited to this. Rendering is completely independant of the project bit depth. Setting the projec to 24 bit is not the limiting factor in how you render it. What is it that you are actually trying to accomplish and why do you believe the project bit depth is important?
