thank you much, i'll try to use it.
that track has some pulsing noise besides pink noise,
is this noise only for audio diffmaker or
would measurements still be correct if i use behringer rta?
behringer can generate it's own pink noise, but i can't use it, because
my car's cd player doesn't have audio in connectors.

It's called pseudo random pink noise.
It is mathematically generated and eventually repeats the same sequence over and over again.

Our brain has a knack for recognizing patterns and you are probably hearing that pattern in this particular WAV file.

(I hear a repeating "thump" in this WAV sample)

Just give this a try and see if it works for you.

There may be other pink noise WAV files on the WEB.
I just haven't searched for them.

Hi,

There are many soft signal generators around on the web that generates pink noise for output through the soundcard. Most use the RND function built in Windows. These generate no patterns.

Simply record the .wav output through the Windows mixer into a file.

Saves to .wav directly as well.

Cheers

You can make as long a sequence as you want with something like Audition, just FFT filter white noise at 3dB per octave.

You can make pink noise right away with Adobe Audition. No need to use a dedicated filter.

Digged somewhat deeper into it to see what quality of noise it generaes. Here the flatness of the pink noise spectrum as generated by AA:
