This is just for fun, but I'm comparing two different microphones recording the same audio source. I want to compare their frequency response, but I haven't been able to figure out how to do that. I have tried the Presonus spectrum analyzer as well as Voxengo SPAN, but i'll be honest, I don't really know what I'm doing.
What would be a good way to do this? I guess essentially I want to see the visual difference between the microphones at different frequencies. |

I just remembered that Fabfilter 2 has an EQ match function, so for fun I did that and set the number of EQ bands to 21. The end result shows me what would have to be done to the second mic to match the sound of the first. Not exactly what I wanted, but it is kind of a cool way to do it.

I figured out how to use the sidechain in the S1 spectrum analyzer, so I'm getting closer. I can see the two different analyses next to one another. Now I just need to figure out how to compare them. There is a "Compare" button, but i haven't figured out what it does yet.

There is some useful info here... It's about how to read a chart but touches on how they are made.

What I'm looking for is a way, inside the DAW, to compare two different tracks, essentially. To visually see the difference for myself. It's not really necessary, but I figured there was a way to do it given the analysis tools available.

Oh ok. Well you could run a frequency analyzer on each track, set the peak hold to infinite and let them run. Then view the two side by side.

Maybe this is what you are after...
https://s1manual.presonus.com/Content/B ... is_and.htm Look at the Spectrum Meter plugin... Send the two tracks you want to compare to the same bus, one track panned hard-left and the other hard-right. Put a Spectrum Meter in the bus's Insert and set it to display L-R and it will show the differences between the two. That would show you where the two are radically different. Put a Spectrum Meter on each of the two tracks and compare to see which one is "overpowering" the other at any given frequency. I hope that makes sense... not sitting at the DAW right now... Another thought... the ProEQ plugin on that same bus as I mentioned above... does it show two different curves for L & R channels? Then you can see them going on the same graph in real-time. |

Yes, that should work! I was using the Spectrum Meter, but had it setup differently. I think the way you're suggesting will show me what I'm looking for. Thanks!

I use Pro EQ for that. Like sending a guitar sidechain to the Pro EQ on the vocal track and you can see both responses, the SC signal is purple. That's one of the reasons why I still use Pro EQ for EQ even while mostly always using the Fat Channel compressors.

Ah there you go... doing that you get both on the same graph!

I have used multi-track Voxengo Span in previous DAWs, but can't seem to get the same setup w/S1.
Melda Productions has an alternative on sale this week. Looks good in current S1 mixdown... https://www.meldaproduction.com/MMultiA ... tiAnalyzer |

Big thumbs up for the Melda Multianalyzer. I think you would really like it!
You can always do a 15-day demo (full functioning- no risk). This video shows this tool way better than I could explain... |

I had read that about ProEQ the other day in another thread.
So the sidechain button is just to compare another track? I guess you wouldn't really sidechain an eq?

As long as you're just doing things for fun, you could try a null test. If you use both microphones at the same time to record exactly the same Source material (such as an acoustic guitar performance), then you can flip one of the tracks out of phase and then mix them together.
The resulting audio will be the difference between the two microphones. Of course this has some inherent flaws because the two microphone capsules can't be in exactly the same place at the same time  and even moving a microphone a half inch can change the sound. But you might get some interesting results because it could show you some differences that are not readily apparent using test equipment. |
