@Noel96;

Hi Noel smile

It's the slope relative to the slope of white-noise.

White noise is the same dB level through the entire frequency spectrum, which makes the slope look flat when viewed at '0 dB per octave' (0 dB change in how you project the slope per octave, meaning a signal with the same dB value will look the same height across the entire frequency spectrum. For example; a -18 dB bass signal is as high as a -18 dB cymbal signal)

For music that slope is too bright though, so music (viewed on a '0 dB per octave' slope) tends to look like it goes downward as you move from low to high frequencies (the high frequencies look like they have less power, because they do have less power normally)

So on spectrum plugins for music you can usually adjust how you want the slope projected on the screen, so that you can more quickly/easy see if your music fits your desired slope.

So to have the music-slope appear flat, you actually make it go upwards as it moves to the higher frequencies. Hence it's expressed as a plus dB value.

A +6 dB per octave slope means that 2 signals displayed an octave apart will appear at the same height if the signal one octave higher is 6 dB less powerful. 2 octaves above it will have the same height if it is 12 dBs less powerful.

So since treble signals are less powerful, this +6 dB slope will make music look flat across the spectrum if the music is mixed/mastered toward that specific brightness.

If you project a white noise signal on this slope, it will look like it's rising as the frequency increases.

So basically, the slope is used to determine how bright your sound should be.

Music that appears flat on a '0 dB per octave' slope sounds too bright, if it looks flat on a '+6 dB per octave' slope it sounds a lot darker.

The slope on your image is probably (I have never used Ozone, so I don't really know how it works) set to a specific value somewhere in Ozone's settings.

I'm not good at explaining, but I hope it makes sense smile
