Oh yeah. I like the rough shape, with the flat.
And that's making me vote "team contrast".
Looking good, I'm sure sounding awesome.

currently it has no eq on mids or tweeters and has an excellent stage with good instrument placement and tonality… the finer details will be interesting to thrash out when it gets better than it is now

So a very interesting topic came up the other day

pink noise we use for measuring with mics

this is quite hard to do so I’ll use four posts… but it was quite eye opening… the Emma cds like many competition formats contain pink noise for tuning with

attached is the rew analysis of the wav file, so I saw this and wondered if my cd rip had gone wrong when converting to a wav file

[dumdum]

How bad is that while we are trying to tune (I should add that lots of other pink noise files from focal, kicker and a load more are as bad as this! God knows why… see my last post on this for why

So next up, I have the pink noise cd quality taken from the Emma 2022 anniversary usb stick, rolls off a little from 19.5khz but does extend upto 22khz, but look at the bass end, can you imagine tuning to the half whitledge curve with that

[dumdum]

So next up the hi res version of the Emma 2022 usb (these are both in wav format so no room for me altering stuff or changing things) it’s flat to 48khz, so accurate… but the same bass roll off…

And let but not least my effort made in audacitys generator, I make an hr long version so I can do a car with no skips or gaps which wrecks spatial averages

It’s 48khz 16bit and an hr long, I’ll leave a link to my Google drive so anyone with the link can download it as well… why they can’t manage to generate flat pink noise I have no idea, but there’s loads that are not flat as we require for correct tuning… mine is flat from 7hz to 24khz so very good for what we require

i should add to test your pink noise I used rew to play the wav file in rta and it measures the output of the wav file while it plays, I just set unlimited averages and it samples while the noise plays

if you have pink noise in another format I used fre:ac audio converter to swap the file format if it’s not a wav file in the first place

rew will generate it, but only for shorter periods and Sod’s law the end/beginning on repeat always comes in the middle of a 100 measurement period

for the benefit of those who follow this... have a little gift from me

Is the pink noise in the centre dash position and in mono

Wow that's WAY worse than I ever imagined. I would have trusted the EMMA one especially.

I'm definitely grabbing your track and putting it on my Google Drive. Huge thanks, that's great of you to do. So good.

I thought all pink noise was created equal. Big thanks

I agree fully that a pink noise track should not have any sudden drop off or wavy curves, but it should also not measure flat though? A white noise track should measure flat/have the same amplitude on any given frequency, but a pink noise track should slope downward from the lowest octave to the highest no?
