2013年9月9日 · Since the dB is a ratio as you say, "0 dB" just means "no change". In the context of digital sampling, I'd consider 'full scale' to be the reference point -- i.e. 255 in an 8-bit system -- making anything less a negative dB value. But unless it's specified, (as in dBa, dBm etc) it's just speculation and open to interpretation.

2010年8月30日 · Too many successsive 0 dB samples in a row (usually four) will light the clip indicator in any audio editor. - 0 dB or 'unity gain': the point at which the receiver is not attenuating (reducing) the input level from the source component at all. All receivers have such a point, regardless of whether it uses an absolute or relative volume display.

Technically, I read - 0,3 db is pretty safe. 100% safe is - 6db. That is the peaks, of course. No peak going above -6db and/or -0.3 db. Don't forget that volume is not really measurable. It is mostly perceived. There is a harmonic balance to be found between high mids and lows. If you have too much lows, you volume will peak and very low ...

2020年10月5日 · Decibel is relative measurement, there are no absolute values. So, assume we define dBA as the relative amount of apples and we define that 1 apple equals 0 dBA. Half an apple would be -6 dBA and two apples would be 6 dBA. Let us also define 0 dBB as one banana. If we now add 0 dBA + 0 dBB what do we get?

2005年10月10日 · Play a modern hyper-compressed CD where the average level is -10 dB and you will get 95 dB SPL. The peaks will still be the same (85+20=105 and 95+10=105) for the occasions when the level on the CD hits 0 dB. I know this stuff can be confusing until you get your head around it. Just don't confuse 0 dB as a digital level with 0 dB on the volume ...

2005年5月20日 · The 0 dB thing refers to your pre-amp not your power amp. My c-j pre-amp does not have dB markings on the volume control, but I know from reading the reviews of it that at about 2/3 point on the volume control is 0 dB. So it attenuates below that point and actually boast the signal (amplifies) above that point.

2016年4月17日 · Please understand that "dB" is a relative term. Using a specified reference, an audio sample can be said to be so many dB higher or lower, but there is no absolute 0 dB. Every piece of equipment can have its 0 dB level defined wherever the manufacturer chooses. For example, the clipping point on my digital mixer occurs at "+18dB".

2017年1月7日 · If that seems counter-intuitive, it’s because the scale is actually telling you “how many dB before maximum output,” or something akin to that, with 0 dB being maximum. This is somewhat obfuscated by the fact that some receivers volumes (like yours) actually move to the (+) side of 0 dB, but that’s the basic idea. Regards, Wayne A ...

2016年4月8日 · So if we set that 0 dB gain is 1.0 factor, and -∞ db gain is 0.0 factor, it means that (if we are considering voltage gain as in a mixing desk fader) : gain = 20.0*log10(factor) therefore : factor = 10^(gain/20.0) If, as described in a comment, the 0 dB gain is at 0.65 factor, it means the ref is 0.65. gain in db = 20*log10(factor/0.65)

2008年2月22日 · This would also depend on the overall maximum indication on the display when fully turned to its max position. Some receivers max is 0 on the display, then you would not set your reference to 0 but say -10 or -15. Others will have a max indication someplace in the + 10 to + 18 range. Then you reference point for the master volume would be at 0.
