FFT Filter

Hey guys,
I want to FFT my signal and split the FFT into two parts from a certain frequency.
I implemented it using two filters and two FFT. but i want toreduce it to a singale FFT and splitting it.
Please find my solution.

I do not completely understand what you are asking. Do you want to take the FFT of a signal before the filter, then extract certain portions of the transform output?
Your image shows two waveform wires entering two filters. Do those both contain the same signal or two different signals?
What will you do with the FFT outputs?
Give us an idea of the big picture - what is the source of the signal(s) and what will you be doing with the filtered results?

How do I make a FFT filter fade over time?

I am trying to apply a FFT filter (underwater shallow) to an audio track, but I want it to gradually fade until we here the original non-filtered audio at the end. I've created a multitrack session, but Show Envelopes does not unclude the FFT filter. Surely there is a way to accomplish this? Please help!

If you add the FFT filter to the Effects Rack for your audio track you can then select Rack Mix in the Automation track and use it to fade between the "wet" treated version and the "dry" untreated version.

FFT Filter Preset Importation / Creation

After using Audition to copy the eq's of two different songs, I computed the difference between them in Excel to make a compensation eq curve. I would like to use the data I collected to generate an FFT Filter preset. I have looked into editing Audition's settings xml file but don't understand how the FFT presets are formatted. The alternative, of course, is to input the eq data into the Audition FFT Filter plugin by hand but this can be a very lengthy process depending on the FFT Size (in my case, 512, which generates 230 eq curve points; right now I'm on around number 50). Is it possible to create an FFT Filter preset by modifying Audition's xml settings, and if so, how are the presets formatted? Thanks

>Is it possible to create an FFT Filter preset by modifying Audition's xml settings?
Technical answer:
I'm not convinced that it is. Currently the most reliable way of modifying (or swapping) presets is to create the one you want, and store it as part of a script. The good thing about this is that once you've figured out how the numbering works, you can edit the script at will. So if you enter all of your points, you can look at how this is stored in the script, and modifying it becomes quite simple. In fact, I suspect that you could probably configure Excel to do most of the work for you without too much trouble at all.
Audible results answer:
I wouldn't ever bother to do what you are doing though - no two songs are the same, and there's no reason on earth why the EQ for one would be anything like correct, or appropriate at all for another.

Which fft filter do you recommend for use with Photoshop CS4?

Looking around the internet, I am having trouble finding an FFT filter that I can download and that is recommended for use with CS4. Any have any help?

Thanks much, but when I click on the link

FFT Filter, Dynamic EQ, Scientific Filters...

Hello
I don't know what types of applications these are good for? I'm scared, help me overcome my fear of the unknown.
I always go back to the graphic eq, parametric eq, and notch filter because it seems to get the job done for me, but I would like to utilize the FFT Filter (what does that stand for by the way?) as well as the others listed, I just have no idea when it would be a good time to use them or just experiment with them.
So, I would like to hear from Audition users who utilize these processes effectively in their work: what do you usually use them to accomplish?...and in what type of situations do you find yourself using them in most often?
Thanks,
Kris

Huge topic - can't really cover all that in one post at all.
FFT stands for Fast Fourier Transform - and from there on the explanation gets technical and complicated, and whilst it won't help you with real-world processing, you do need to understand that long window sizes work better on LF than short ones do. And just to make it confusing, a long window size means a smaller number, and a short one is a large number.
In Audition, some of the filters are finite impulse response types (Graphic equalizer and FFT ) and others are infinite impulse types (Parametric equalizer, Scientific filters and the notch filter) - these are the two basic models for constructing digital filters. If you want to know more about these, then unfortunately it gets technical - again! Basically, the infinte type uses a recursive feedback model (and can have steeper filter sides as a result), and the finite one doesn't. Most people think that they sound 'different' as well, but that depends rather on program content - you have to use your ears. The big problem with things like the Graphic EQ is that if you aren't careful there will be a lot of phase shift at the transition points between one band and the next one, and this can have a pretty adverse effect on the sound in general. I never use it for anything, because there's never anything that I want to accomplish that I can't do with Parametric EQ, but YMMV. The notch filter is primarily only intended for removing hums, and this needs careful use too, because it's very easy to introduce ringing in the filter skirts.

Fft and automatic filter

Hi.
I have a couple of data from a measure and want to do an automatic filter.
The way how I want to proceed is the following one:
I want to make an FFT on the data, and then make a frequency detector.
The unwanted frequency are 50Hz and 100Hz.
IF (and only if) the 50Hz and/or 100Hz are detected on the FFT (automatic detector), then, I will filter the data with 2 band-cut filter (one with 50Hz central frequency, and one with 100Hz), then re-made an other FFT to make sure the frequency I have removed from the datas are there any more.
How can I do that?
Is the way I want to to it succesfull? If not, why?

Thank you johnsold.
I have test your vi (and try to understand how it works).
Please correct me if I'm wrong : You change the value of the data scaned if the signal data is over the threshold.
Question : what is the command that fix the value of the threshold?
Other question : my array is a 2D array. how can I do the same thing with it? (with a for loop, and indexation I suppose)
The last question is : I have puted a reverse FFT to see the signal filtred, on the graph, the first values seems to be higher than the initial array. why? is it a mathematical error? (no problem with it, I just cut those first values out, but I want to understand why...)
If I understand well, I jsut have to put the same thing in serial to have two frequency filters.
Other question : Why you dont use a filter bloc made in labview?
The way i was thinking the vi is as follow :
I test the signal with a FFT, do the over threshold detection. If one (or two) peak(s) over the threshlod is detected, the you filter the signal with a simple filter.
What do you think about this method? Is it a good way to construct my application? If not : why?
Please find an example of the way I was thinking the vi (doesn't work correctly, but the idea is there)...

Time-domain accuracy of Audition's filter functions

Thanks for your reply, Steve. I'm not sure why that would be a 'very strange question' though. 'Brick wall' refers to the sharp transition between pass band and stop band. It's a commonly used term. I prefixed with 'near', since I'd ordinarily moderate the transition to avoid Gibbs phenomenon.
I understand the relative merits of FIR vs IIR re consistent delays, and I would not consider using IIR in this case. The question was intended in context of Audition's filter implementations. It -is- possible to avoid delays by doing an FFT, applying coefficients to the FFT output, then IFFT. But I'm not sure there is more to the approach used in Audition's "FFT Filter". IOW, I was looking for insights on what delays (if any) to expect from the Audition "FFT filter". I hope that is more clear.

It's not mentioned because there's nothing at all wrong with it - as this reply attests...

It's a term certainly, and I know exactly what it is - but it's not a mode, as such. The mode of a filter would imply something about the structural content of the filter - IIR and FIR are modes, if you like - but brick wall only refers to settings.
I understand the relative merits of FIR vs IIR re consistent delays, and I would not consider using IIR in this case.
Ah, that's the crux of the problem. It's not even remotely possible to tell you what the effect would be, because we have no idea of what you are using it for - you will have to be a lot more explicit.

Calculate frequency response using FFT and inverse FFT

Hi,
Attached is the program using FFT and inverse FFT to filter a time domain signal. The frequency response of the LPF can be obtained by using the chirp signal from 0 to 5kHz. However, I don't know why the signal obtained from a sine wave input is so strange. The amplitude is wrong and has a envelope outside. Please help to point out what's wrong with that.

fft filter.vi ‏87 KB

If you check the help text for sine wave.vi you'll see that it generates the sine wave based on the following formula:
yi = a*sin(phase[i])
for i = 0, 1, 2, …, n – 1 and where
a is amplitude,
phase[i] = initial_phase + f*360*i
This means that when you input a=1, f=0,1 and initial_phase=0 you will get a sine wave that is based on samples at every n*36 degrees; i.e. at 0, 36, 72 etc...due to this sample rate you never see the full amplitude (+/- 90 degrees), the wave is clipped at the top. If you input an initial phase of 64 degrees you will get the full amplitude, but the wave is still deformed due to digitalization...
The lower the frequency you put in, the closer the digitalized representation will be to the true sine.
Use the Waveform Generator VIs from the analyze palette if you want to have more control over the wave generation (sample rates etc.). (Not available if you have the base package.)

Audition 6 Crashen when previewing or applying effects

Hi
I recently installed the Creative Suite Master Collection CS6 Windows version of my new Retina MacBook pro (new 13" model) and I'm having a few problems with Audition. The main problem is that when applying effects (like a FFT filter or Stretch and pitch) Audition would crash when trying to either preview the effect or apply it.
One example is when trying to change the pitch of an audio file. Normally I use “Audition” as the algorithm rather than iZotope. Audition would crash when previewing the effect or when trying to add it. It doesn’t crash when using the iZotope algorithm. It also happens if I try to apply reverb effects too.
This Macbook Pro I’m using is running Windows 7 Pro x64 via Bootcamp. I don’t have a lot installed on it atm & both windows & the master collection are fully activated. I had an older Macbook that never had this problem before. I’ve also tried Audition from CS5.5 on Mac OS X & it doesn’t have this sort of problem.
These are the errors that show up acording to System info.

The sound hardware found on this Macbook is a Cirrus Logic CS4208 (AB 94). Atm I'm using the stock drivers included with Bootcamp. Also, both Windows & adobe software are all up to date.
Can you please help me out?
Thank you

Because my main computer is a PC with CS6 & i'm usiing my macbook as a secondery PC. Yes I could use the mac version but all my projects are done on CS6 while I have CS 5.5 on the mac partition. Plus I'm not interested in updaing to CS6 for mac (if it's possible since ny CS5.5 is an upgrade from CS5).
Anyway I just want some help fixing up Audition for windows.

How do I see the frequency of a point in spectral frequency display

Hi all,
I have recently tried out Au 6 (I use Au 3 at the moment), and though I very much like almost everything so far, there is one HUGE problem...how do I see the frequency of a point under the cursor? In Au 3 this appeared in the status bar, but I can't figure out how to see it in Au 6. I spend a lot of times editing bird sounds, and this is an absolutely vital feature for me; without it I will probably have to stick to Au 3. A huge thanks for anyone who can help with this!
John

I've tried the method recommended here for a while, and I must say I am extremely unimpressed. Sure, you can get grid lines to be fairly accurate. But by the time you've zoomed in to the spot to get the desired frequency (see another post recently by me about the problems with THAT), mentally converted the value into hertz instead of kilohertz to use in the fft filter or where, it's take 3-4x as long, minimum, than it did in Au3. Why on earth did Adobe get rid of this feature? Every other sound editing tool I've used has it. It's as basic as the eraser on the end of a pencil...sure, you can get by without it, but it makes the whole tool so much more useful. I edit hundreds upon hundreds of sounds, and anything that makes editing a sound take that much longer is a serious issue. Regrettably I cannot justify a purchase of Au6 at this time, and since I've moved to a mac I can no longer use Au3. So this will probably be the end of me using Adobe audition.

How to remove Plosive sounds in Adobe CS5

Hi, I am singing into my dynamic mic using adobe cs5 and for some reason I cannot avoid the harsh plosive sounds being picked up by mic.
When I play it back it makes a huge "PUH" sound and really doesn't sound very nice.
Im sure a program like CS5 will allow me to remove these harsh plosive noises but I dont know how.
Please help
Thanks

Well, all the stuff about getting a recording without the plosives is well and good....but if all you have is the recording in post, then the FFT filter is a good tool to work with.Highlight the plosive (and only the plosive. Try to avoid the rest of the word) -- it will be pretty easy to see in the wave file. Go to the FFT filter in Effects Bring everything below 80Hz down to zero. Then draw a curve so that 100Hz and higher is at 100% and start playing with the curve to find the right amount of frequencies to take out.
I've found in my years of radio work, that cutting out frequencies below 100Hz and leaving the rest alone will work good enough about 60% of the time. There are some plosives that go up to 250Hz and higher...you really can't fix those to take them completely out, but you can make them better. Sometimes it helps to also reduce the amplitude some after you've applied the filter.
But, you'll find that people who pop will pop A LOT...and they always seem to be saying (or singing) things with a lot of P's. So it's always better to use pop filters, mic positionioning, vocal technique, and such during the recording. But I think you'll find that FFT filter will be your friend when all that other stuff isn't enough.
(BTW, I'm sure there's probably somethig you can do with the magic healing brush to accomplish this same thing, I just haven't futtzed with it enough to know how to do it there).

I cant use all my effects in audition. why?

For example Filters and EQ i can only use:
Graphic EQ
Notch Filter
Parametric EQ
AND I CAN'T USE:
Dynamic EQ
FFT Filter
Quick Filter
Scientific Filters
It says (process) behind those i cant use, why and why wont they work?

The first three are "Real Time" effects the others aren't so need to be "Processed" to apply to the audio. These are for use in the Edit View where editing is destructive. In the multitrack View editing is non destructive therefore can only use real time effects. Were you trying to use them in Multitrack?

Can anyone help me with this- recording at audio signal in the upper frequency region of the audio s

Using Audition, how would I go about recording an audio signal (voice) at
14,500Hz? I know this would be outside the frequency range for the human ear to hear, but that is the point of my question. Any help would be very much appreciated
Thanks!!!!

You are thinking about it absolutely the wrong way if you think you can "convert" a voice file to be only 14.5kHz. You need to think of a control frequency (14.5kHz) being modulated by the voice line you record. You can't just change the pitch of the voice file or use the FFT filter to eliminate everything under 14.5kHz. It won't work that way.
Try it yourself. Record a voice line. Use Pitch Shifter or pitch strech to change the pitch on the voice. Crank it up all the way to highest possible pitch. Listen to it. Painful isn't it? Could you understand anything? Thought not. Then go to the FFT filter. Reset so it's flat. Add a break point (click on the line) at 14.5kHz. Then click and drag the line below 14.5kHz and bring it to zero. Listen to it. You get the occasional movment if you watch the Frequency Analysis window, but certainly nothing audible to my burned out ears.
The direction I would look at is using the Vocoder effect in MT. insert your voice line into the MT window. In EV, create a new file using Generate Tones at 14.5kHz of the length you need. Insert the tone file into MT ABOVE the voice file. Select and highlight them both. Still in MT, go to Effects>Vocoder. Make your Control Wave the voice file and your Process Wave the tone file. Hit OK. A new file (that looks blank) will be created. Play it in EV with the Frequency Analysis window open and you will see activity at 14.5kHz. This is amplitude modulation (AM). Will it result in anything subliminal? I doubt it, but it would depend on how much you belive subliminal messaging works.
Didn't an earlier version of Audition have some subliminal effect? Could it have been as far back as CEP 1.2?

Make them sound like a megaphone

I am trying to figure out the best way to make VO sound like it is coming through a megaphone, any tips? Audition 3.01.
Thanks!

Here are some general tips that should get you in the right direction:
use the FFT filter to create a tight filtered spectrum. You want to kill everything above 3 or 4 khz and everything below say 500hz. Megaphones have horrible frequency response.
dynamic compression. a megaphone's horn has no real dynamics to speak off...using dynamic compression will help to simulate this better
distortion: a megaphone adds a slight bit of distortion...you may be able to mimic this with enough compression..
mostly the biggies are the stuff you do in FFT and dynamic compression.
you can add echo if you want.

Scripting Docs and Examples?

I've been looking all morning for scripting documentation. Does it exist? If so, where can I get some?

Here's documentation on the scripting FFT Filter arguments I (younglove) did some years ago:
