Hello,
I would like to hear your opinions please!
I've been researching the topic Re-EQ of my audience recordings for some time now.
Until recently, I did not edit my recordings EQ-technically and in principle always left RAR. If necessary, only an increase of the volume or a channel adjustment came into question.
It was always clear to me that I could improve the sound of a recording by correcting the EQ. But I was just too insecure to screw around by ear at the EQ - virtually without "scientific control".
Of course, I make sure all RAR recordings of my concerts have a backup, only edited versions came to a "release" but, as said before, without EQ post.
On the internet I came up with the idea to apply the EQ of a "Pink Noise" to the recording.
Short for the term "Pink Noise":
"1/f noise, also known as pink noise, is a noise that decreases with increasing frequency. In acoustics, 1/f noise is perceived as a noise in which an average person perceives all frequency ranges of the audible sound spectrum as roughly equal. "
Accordingly, "Pink Noise" should be regarded as an idealized frequency response - just without musical content. ;-)
With the iZotope RX program, I can generate a track with as many seconds as I can "Pink Noise". If you look at the frequency spectrum of such a "track", you find that it is very linear and balanced. Most of the professionally mixed or officially released pieces that I've examined to this effect have followed a frequency response close to this "pink noise" line.
Secondary topic: The current trend in the field of mixing even goes so far that the audio track of each instrument is turned down so far that it just disappears behind the "Pink Noise" or is no longer audible - the finished mix sounds very balanced.
OK, back to the topic: If I now apply the EQ of "Pink Noise" to 100 % on my track, the song begins to sound really good. If I then look at the new frequency spectrum, it comes damn close to the idealizing course. It is much, much more balanced and also the "gaps" were somehow "ironed out".
As a comparative example, I took a piece from one of my audience shots:
Simon Phillips's Protocol IV - 2017 11 11 Muenster DE - 03 Pentangle.flac

I would be happy if one or the other here in the forum listen to the times or could compare it.
Cheers!
