Questions related to the asFFT Xtra http://www.schmittmachine.com/support/list.php?4 Thu, 20 Jun 2013 05:26:26 +0200 Phorum 5.2.6a http://www.schmittmachine.com/support/read.php?4,147,147#msg-147 http://www.schmittmachine.com/support/read.php?4,147,147#msg-147
I am able to play the sound and capture the values for 3 bands of EQ (bins) and then successfully play it back and execute my trigger when it hears that frequency played back.

The problem is that this only works with 3 bins. and only 60% of the time. Other times it misses the mark. I rather query 15-20 bin samples to be very accurate.

To get it to work at all I also must have normalized and equalized set (which is fine).

For what I am doing I must run the project at 25FPS. Is this one of the reasons I am not able to do much past 3 bins? I tried speeding the FPS up so that when looping it is checking faster, but does not seem to matter.

Do you have any suggestions to improve the recognition of more then 3 frequencies. tried increasing time smoothing but did not help...but maybe I need to try that more? This may be a limitation of lingo not processing fast enough? processing sound level works really well , but not as accurate as FFT

My native language is french: Quebec,Canada

asFFT is a very interesting Xtra but what happen with Windows Vista ?

I Dont try it...]]> manege asFFT Sun, 21 Sep 2008 23:15:38 +0200 http://www.schmittmachine.com/support/read.php?4,69,69#msg-69 http://www.schmittmachine.com/support/read.php?4,69,69#msg-69 im wondering if anyone can help me. i am trying to design a 3d equaliser using the asfft xtra. so far i have been able to export the w3d file and get it into director, and then get the individual balls to move if a mic input is present, but i want to seperate the frequencies of the sound into groups say 200hz to 350hz for one ball 350-1k for another and so on. If someone could point me in the right direction coding wise it would be greatly appreciated

i am a complete beginner at this and im amazed that i have been able to get this far, but the project is due in fairly soon and i would appreciate any help you could give.
i have attached a jpeg of the design and a link to a video of the first stage, im not sure they will be any help.

Thanks very much

- Download if needed Checkbox on in Director
- Upload the packadge files (.ppc, .w32, .carb) to the direction in xtrainfo.txt (my server)

Im using Shockwave3D and Havok also.

When publishing from a PowerPC (Mac) there is no problem, the application works great in any browser (safari, mozilla).

In Windows i found a problem, i have also configured the xtrainfo.txt to use my server, when i publish the browser says that there are problems in shockwave.]]> grifu asFFT Sun, 02 Mar 2008 20:22:59 +0100 http://www.schmittmachine.com/support/read.php?4,52,52#msg-52 http://www.schmittmachine.com/support/read.php?4,52,52#msg-52
I am building a simple test app that takes asfft and uses microphone input to adjust the size of a w3d object.

im getting an object expected script error

ive got two scripts one to do and one to react

do_asfft:

property gFFT, gBins
global values

on beginSprite
-- creates xtra instance and checks it worked
gFFT = new(Xtra "asFFT")
if not objectp(gFFT) then put "error : 'new' failed"

-- sets the number of bins/ frequencies you want (must be power of 2)
-- can be between 2 and 256, 8 works well, any lower and its not very accurate
-- try using setParams(gBins, 4) if you want it to be more accurate, but cost in processing time
gBins = 32
err = gFFT.setParams(gBins)
if err = 0 then put "error init:" & gFFT.getError()
end

on enterFrame
if objectp(gFFT) then

-- get mic data, returns an array/ list. values.count will = gBins
-- 100 is the number that full volume will be- i used 100 as 100%
-- but you can use any number even 11 like spinal taps amp!
--
-- true, false means normalised, unequalised. normalised sound will show volume
-- otherwise it will only show frequency- the equaliser makes mine crash!
values = gFFT.getFFT(100, TRUE, FALSE)
if values = 0 then put "error reading:"&gFFT.getError()

--put values
-- dumps out global var values, tab this out and it can still be used

--put values

-- from elsewhere, read the list using:
--
-- global values
-- repeat with i = 1 to values.count
-- put values[i]
-- end repeat

end if

end

do_react:

property n, spritenum, s

global values

on beginsprite

s = sprite( spritenum )

n = random( 32 )

end

on enterframe

member("test").model("test").transform.scale=vector(2,5,3) * values[1]

end


can anyone see my problem???]]> defboyuk asFFT Wed, 30 Jan 2008 19:42:17 +0100 http://www.schmittmachine.com/support/read.php?4,49,49#msg-49 http://www.schmittmachine.com/support/read.php?4,49,49#msg-49
surlist = gFFT.getSourceList()

-- 1

??

Is it correct? I'm exepecting a string.

From this laptop your Shockwave demo says: Unknown source

From the same (i suppose) dir file the error is: Error reading: Unknown

Is this soundcard not compatible? It seems strange, maybe i make some mistake.]]> tyler77 asFFT Fri, 07 Dec 2007 12:14:58 +0100
