There is a offer on for the Inspector XL for a limited time only, which contains s a good frequency analyser (frequency analyser/spectrum analyser/ 1/3 octave analyser) at
http://www.elementalaudio.com/
alternatively firium, that someone else has mentioned is available there also.
There are also spectrum analysers in cool edit, soundforge etc. There is also a spectrum view thingy in the free editor audacity.
Fruity 6 I believe has some sort of spectrum analyser in its up and coming compressor.

Dear All,
Okay
I did read all this topics, But I cant fully understand the holle Spectrum Analyser process.
I have some doubts,
First: After open the Spectrum Analyser at the main channel mix to see all channels on it, I dont know how to analyse the "images" that the Spectrum Analyser gives me,...
Does anybody have a tutorial about it, Spectrum Analysers, using it in Logic or Sound Forge?
Because I know how I do I open my Spectrum Analyser on my Logic Audio music, but I dont know how to analyse it,,, somebody help me please!
Thanks for all

to schuenck:
mmhh.. i think that what you need is to start from the basics, learn the physics of sound waves, the theory behind what is frequency and amplitude... then you will fully understand the graphics in the spectrum analyser...wich analizes the amplitude of frequencies in a given sound track!
then it will lead you to the crucial subject of MIXING these frequencies.
but now er mate just read books and tutorials i have to stop now it could be extremely long and painful to continue.
this forum is super good and fun but you will make more fast progress with books and tutorials...
hope it helps in showing the way....
.... :o)

To tribalizer:
I think I have an basic knowledge about it.
For example, I know I have to eq my sounds; Bass and Kick between 20hrtz and 900 hrtz, synths from 900 to 5000, break beats from 5000 12000 and go on...
But I trully don´t know how to "use" the spectrum analyser,,,,,,,, How do I know what freq I have to change? What signals show me I have to changue something, sound, some freq?
Thanks ;-)

The signals you should pay attention to are the ones your ears send to your brain. A spectrum analyser can normally only really help you when you've decided exactly what it is you want to do. One thing it can make much easier though is cutting out areas of the sound in the extreme highs and lows - you can use it to very easily see sonic rubbish either side of the actual sound you're working on, and thus determine a good starting point for any high or low-pass EQ you might want to apply.

Well, although people keep on saying that you should trust your ears, spectrum analizing is very helpful and very used by professionals. There s nothing more accurated than a visual image of your track to help you making subtle changes in final mixes. Once you learn the acoustic and sound theory you ll be able to understand the information regarding wav shapes, present frequencies, dynamics, etc.. Changes performed on the track sounds can be visualized through spectrum. And remember that if you don t have some real flat and accurated monitors, you ll probably be wrongly persuated about yur mixdown overall quality. The best solution is to use both tools: ears + spectrum analyzes
The best advice I ve read about spectrum analyzes was wrote by D-Alien on a topic I created about this subject sometime ago. As people hardly remember to try the search funcion in the website (you d find almost all answers you need..) I ll post his wonderful tips here. Once more I d like to say "thank you" to D-Alien for his very kind effort to help me ( and he really helped a lot):
"sure spectrum analisis can tell u a lot. it can tell u if the side-chain compression u use between kick and bass is correct. if really the subtle part of a kick compress just the subtle part of the bass so that the same dont loose its "color". ...but! using the spectrum from soundforge... is just horrible. in this page: www.exactaudiocopy.de there is a freesoftware. dld it. install it. open it and enter in PROCESS WAV function (Ctrl+E) than give the closest zoom possible (the speed of the refreshment depends on your video card) and now the grafics looks Different! u can see very welol what is going on.
here I've posted an Image:

Spectrum analisis from the begining of one of great Mubali tracks...
I've marked u the kik and bass. Its so clear. First u see the clik. u can tell very well which frqs it ocupies. than comes the middle part. the Hit! and the last is the subbass. thats why a good structured kik will have all this 3 main parts of its body very well defined. it varies from kik to kik how exactly it looks, but all great kiks always have this 3 parts of their body present. U asked about how u can see if attack, decay, release comports. well its obvious in the grafics. U shold know that in 145bpm 1/16 of a note needs about 20ms to reach the next sixteenth. (from great MIKE A tutorial!!) so, if u dont want that the subbass of the kik interfears with the notes of the bass, try to make the kik as short as u can. and at the final stage of the mastering of your track it will become it nesecary power from the last multiband compresor that is used to pump up the track. but u Do need a very well defined kik and bass notes, and thay Must not interfere, otherwise, saturation can occur. This can be resolved using sidechain compresison, a little EQing, and some litle stereo spread so that both can share the same frequancy range. LAter u see the bass notes too. u see just 3 of them cuz the first one has been eaten by the sidechain. the other notes are well defined, every note consist of 3 small peaks, they are because of the distrorted and very deep bass Mubali use here. in the other image u can see the same song from a smaller close up. u see very well what exactly the bass, the kik and all other sounds are doing, u can see the low cuts, the high cuts, the sidechain, compressions, the Eqlizing, and a lot more secrets we cannot percieve just by ears." by D-Alien |
