Does this also mean that audio equipment in general will display a spectrum with this kind of logarithmic offset adjustment?
- mjr00 1y agoMore often than not, yeah. On the music production (rather than listening) side the two EQs and spectrum analyzers I use most frequently, FabFilter Pro-Q and Voxengo SPAN, both use a 4.5dB/octave tilt by default. You can adjust it, but I've never done so.
- Acen 1y agoPractically all of audio land is logarithmic. The orders of magnitude in power/loudness is pretty astonishing. When introducing decibels to new audio engineers, we generally introduce it as a 3db increase is a doubling in power, a 10db increase is a 10x increase in power. It gets silly when you start talking sound pressure level, because how people perceive a 10x increase in the output power, is about a doubling of the perceived loudness.
- tverbeure 1y agoWell, yes, of course it’s logarithmic. The question was whether or not the audio displays have a correction to make pink noise render as a flat horizontal line, whereas general test and measurement spectrum analyzer would show a tilted line.
