Spectrum analysers explained

► Mixing tutorials : www.adsrsounds.com/category/mixing-tutorials/
In this video we will discuss Spectrum Analysers, how to read them and modify them to display what we need to see. For those not familiar with using such a tool this is the perfect introduction. Using the free plugin Span from Voxengo I will demystify the various controls contained within, and similar controls are found on all analysers.
Whether you’re a beginner or pro, having a visual aid that performs realtime frequency analysis to help you in the music production process saves time in problem solving and helps you produce better sounding mixes and masters.
Lesson key points:
0:12 - Introduction
0:42 - What is an FFT?
1:21 - Adjusting settings in our Analyser
6:32 - Advanced settings
10:52 - Creating user presets
12:01 - Other meters

The intro song starts the same as my alarm in the morning and it gave me chills lol

GREAT VID !!!!!Thanks for the help. This is a very intuitive plugin. I found that when you solo a freq. range (9:55) and scroll while holding the left click the Q factor changes. Moving the mouse changes the gain. So you can really tune in to find "Honks" at certain freqs. like 3.2khz on a harmonica

[@kobalt77]

Jeez man, I love SPAN, but had no idea it could do half of this stuff, hahaha, absolutely fantastic video, thank you so much.

[@holotropik]

I use this plugin and have been meaning to learn how to get more out of it. So thank you for posting this video, perfect timing! ;-)

[@HazyJ28]

I couldn't help but notice your correlation meter indicates a very good phase relationship between the components of your mix 🤙

[@djrobitonzz]

One of the best Videos on spectrum analyser, thanks for this

[@korglegend]

Brilliant been looking for explanation of Span, you covered all the bases, thanks

[@in_10z]

Using Span forever and didn't know about the CTRL click command for copying exact frequency! Thx.

[@_lfab]

Good stuff! Always been a fan of spectrum analyzers, this tutorial helps take this tool to the next level.

[@markdavenport2613]

SUPERB! I learned a lot from this. Thanks for the post!

[@epiphoney]

That's is just what I've been looking for. I want to design synth sounds with it compared to real instruments. Most people talk about mastering.

[@jamesrossmusic6013]

Excellent post... Thank You Sir!!!!

[@garyshore489]

Glad I saved the link to this when I happened to see it and finally got around to checking it out....installed VS+ a few months ago,studied a bunch of tutorials and figured out how to use it but wish I had seen this then too as it showed me a whole bunch of other stuff I'm going to start using now.... Curious about the display re-the line shown vs.how I have mine set up where it shows a solid block below the line...???

[@DJVICTORIUS]

Great tutorial video and good plugin Thanks!

[@adekunlehamod7374]

Pls i have a question that may not be in format of what is being discussed but still about specan. I'm using Anritzu MS2723B. I can capture the current measurement on the specan using the software at a time to see how the carriers are doing. But how can i get a record of how the carriers are doing throughout a day from the specan? I will really appreciate response from you guys!

[@Darro2017]

Hello Thank You for posting this video. It is very informative. I watch it with pleasure. Regards

[@gilormsplay]

V. useful vid. Thanx.

[@fkcoriander]

Great Video! the only problem I have is to understand the Volume (Y-axis). I mean, I know that there are many different dB meters... but I just can't figure out the relation between the dBFS meter and the horizontal lines from the Y-axis. Like -6dBFS are about -43dB on the readout in the upper right corner. When I want to know the difference between two frequencies for example... I can't find out the reference here, especially when you alter the slope for example. I was like searching the web for almost 2h now... I'm doing music and all the audio engineering stuff for almost a decade now but I just can't get my head around this particular problem :'D

[@keithrowe1007]

Thanks for the great tutorial. Now if I ever heard that Boppy little calypso number again I’ll make the news.

[@vibesandvinyl6903]

Great tutorial, this helped a lot ♨️

[@briancase6180]

Thanks for a good video. The other thing I love about span is that it shows the crest factor. This is your key to getting a loud master. Keep the crest factor of your mix relatively low, and you have the potential for a loud master. Be careful though, you can over do it and sacrifice dynamics.

[@molunz4598]

Excellent tutorial, thank you!

[@audioenginearinginstitute85]

I was always under the impression that PINK NOISE gave a flat response on a spectrum analyzer (Equal energy per octave). And that WHITE NOISE would give a rising slope to the right since it has equal energy per frequency. (The higher octaves have more Hz...) I thought that I had read that PINK NOISE was more appropriate to use when testing speaker frequency response with a spectrum analyzer - right?

[@Jubidar]

CTRL + Mouse 1 + Scroll Up/Down does not seem to wide/narrow the band? Any ideas how to turn this option on?

[@reachforkills]

Can someone PLEASE explain to me why all spectrum analyzers have negative dB's on the Y axis??? This confuses me to the point where my head hurts as my mix level is clearly showing positive dB's... Why is everything shown as negative? I'm assuming there is some sort of formula being applied to the original input but why... Why wouldn't it just show me the actual dB levels??? Much appreciated if anyone can help.

[@g4m3reoin14]

Thanks for this. Now ive a better understanding :)

[@MrMiles-gi1hl]

This is great... thank you.

[@ProducerKayo]

So what? is the spectrum like a reference for mixing? like is the goal to have an even plane? I'm trying to understand whats the spectrum for. Is this something I'd use during my creation process to level my sounds on the master? get back to me when you can!

[@quazrmusic]

thanks so much. great video

[@jcolinger3]

Thank you. Nice video. Helpful.

[@shakeelsahito619]

Test a gas stove at, e.g., five different powers. Record the acoustic signal and the sound pressure level [this latter will not be a precise value, but their ratios will be]. For the acoustic signal, you can use, e.g., the Spectroid or Spectrogram app (there are a lot of apps out there to do FFT on the microphone signal). For the sound pressure level, you can use, e.g., the Andro sensor app. Evaluate the measurement result, can you please do for me as i am getting problem while testing

[@NaikyPedraza]

Nice video, thank you!

[@chimpalahee]

Whats the difference between this and Ableton stock?

[@yogibtube]

Thank you 🙏🏾

[@TheTonyTitan]

Thanks

[@rizla4606]

Good video nice explanation

[@drummersaad]

Thank you.

[@blck_tv9408]

Hey thank you very much. It’s great. Who the fuck dislikes this 😂

[@gurindersingh7933]

sir my span is showing only two input and how can i route more then two input like kick,clap,hat,snare .

[@gregrelmueab2142]

You have to put this Plugin on the Master Bus.

[@DocBeasty]

anyone else having trouble getting it installed? I tried doing it as a VST and as an AU and it just wont show up in logic and I can't seem to find any help on that anywhere

[@john8451]

There’s an install .txt doc that comes with the download.

[@ermanitosinoreja4725]

You got it man! Luv it!

[@yolo_ofc]

great thanks alot

[@kojik4271]

when you ducked the frequency at 7:20, how come you didnt isolate with a narrower bandwidth?

[@preetamthapa5120]

HOW TO PASTE IT TO THE EQ PLUGIN ? SOMEBODY HELP

[@Frobbl]

I don't get how they thought the slope function would be a good addition. It is so misleading and confusing. With it on frequencies suddenly get displayed way louder or way quieter than they actually are. Not to mention everyone is used to analyzers without this and will be terribly misled.

[@kojik4271]

dont buy like an idiot like me. :/ you could get all the necessities free. I thought mine had a bug bc it was free so i bought it, but it turned out to be another issue. ah well, support the creators.

[@leandrotaibbi]

thanks
