Well, what i mean is: A piece of music, peaking at a given level, for example 90 dB SPL (where the C-weighting matters), will seem louder when the RMS level is higher and the dynamic range is smaller. The same signal or piece of music, peaking at the same value of 90 dB SPL, will sound more quiet if the RMS level is lower and the dynamic range is bigger.kulture wrote:Sorry to be pedantic but you said that RMS is the perceived loudness in a previous post. Loudness is affected by the equal loudness contours (a psychoacoustic phenomenon) and many other elements/phenomena. Therefore, RMS is literally what it says it is, root mean square, merely a statistical tool for finding a kind of average of sinusoidal magnitudes -- different from perceived loudness.
Therefore, RMS has a relation to the perceived loudness. Maybe i should not have said that RMS is perceived loudness, but it is related to it.
The commonly used term "dynamic range" stands for the range between the highest RMS level and the highest peak, as stated in the quote above. I think what you refer to is the signal/noise ratio.kulture wrote:EDIT: oh, and with respect to dynamic range, I may be thinking of something different. Because the dynamic range can be defined simply as the lowest signal to the highest signal (the range of levels). Without dither, the lowest signal will be the quantisation error. With dither it will be the dither (noise). Perhaps in mastering or some other process there is a dynamic range term which uses the upper RMS of an entire track?
The term dynamic range is widely used in mastering, that's correct.
