I am just trying to understand what the values sent back from computeSpectrum(bytes,true,0) mean. I have values ranging from 0 to 1 for each float i read from the byte array but does each value represent a range of Hz

View 8 RepliesI'm developing using Actionscript 3.0 for Flash Player 10.3.I'm using computeSpectrum() on a loaded .mp3. Running *Event.ENTER_FRAME* to get snapshots of each sample in an byteArray.The ByteArray contains 512 values (256 for each channel). These values are FFT Spectrum, ranging from 0 to 1.I can't use the peak frequency for each of the samples (as I found found out!) because the highest value is not necessarily the fundamental frequency. As a result I'm getting lots of random values all over the place.Of course I'm getting some correct too, but that's not enough.
View 4 RepliesI am receiving xml from a webservice call that contains a nil="true":[code]I used the Flex DataService (webservice) wizard to create the service objects for the cacheEntry component. This object will be serialized later on a different webservice call and stored in a database.I set a breakpoint on the set SystemFK method in the service object. It appears that the value passed in was an empty string!Allowing this value to be an empty string will cause problems in the webservice implementation in Java on the other side. Since the database value was null it is expecting a null in return, If I avoid setting this value, the serviceObject should send back a null which will make the database happy.How can I detect that a nil = true is present in the XML in order to avoid setting this value?
View 1 Replieshow can I get the bytes loaded and bytes total, from a JPG i'm loading using loadMovie? the point it's making a loadbar
Code:
image.loadMovie("pic.jpg");
What I'm trying to do is get the total bytes of all the files I want to load and display the percentage loaded of total bytes and bytes loaded of all the files. Its a slideshow so i want all the files loaded and then it will play. I've looked at bulk-loader but it wasn't what I needed. The image are loaded from an xml file. I think I would need to create an Array and then find out the total bytes but I don't know how to reference the loader in the progress.

is there a simple way to just pull back a true or false value from an associated javascript file to a flash file? here is what i have:
Code:
var bincheck:Boolean = fscommand("eval", "parent.check_bins(\'"+img+"\')");
if (!bincheck){return false;}
return true;
check_bins(img) is a function in my javascript file that simply iterates through an array, returning false if "img" is found. im simply trying to get the true or false value back into flash, but its not proving that simple. i added a couple alerts so that i could see what the "bincheck" value was, and i keep getting an 'undefined' value for "bincheck" in flash.
about.buttonMode = true;

View 5 RepliesI'm a begginer flash game developer-ish individual working on my first project - An economic game with RPG elements, I'm mixing AS 3.0 with Flash CS5 (for the graphics, buttons, tweens and the simple stuff in general since it's easier for me atm than scripting it). The trouble started when I had to script in variables. I've sorted out a couple of issues but a few still remain:
1. I need to limit three of my main skills to 0-100. Only managed to stumble across tutorials for AS2,
2. Each character will have 3 main skills, and then the 18 secondary skills will be calculated from those 3 values. This works fine, when I modify existing variables directly in the code. The thing is that I created those buttons that add or subtract from a certain skill value, but when I press them the var changes but all of the 18 skills remain unchanged (as if they do not refresh themselves - i was thinking about an eventListener waiting for a change in skill value but if I would have to do one for every one of the 18 skills in conjunction with the 6 buttons to change levels - so 144 functions - im thinking maybe an array...but I'm such an actionscript newb that I can hardly translate the tutorials into my ideas.
3. Also wondering how to create a pool of unused skill points so when I add points I can't max it out right off the bat but rather take it from that value instead and once it's 0 you can't add points anymore.
4. Last but not least, I'm having trouble creating global values. My main menu is in scene1 and when I press Newgame it goes to scene2, the problem starts when i go back to main menu errors keep showing up (since scene 1 has no information about statistics but a function probably keeps asking )which means that the program can't get access to an attribute or a method of reference for the null object at MainMenu_fla (don't be fooled by the file name, I have everything in 1 fla file)Of course an error pops up for every skill, main or secondary.
I'm working with a web service and am returning an array to a field (that I set the data type as an Array). The result thus far is "[object Object]". How can I get the array values back out as a string?
View 0 RepliesUsing the example found in the class documentation, you'll notice the bass frequencies are crammed on the low end too much, and the higher frequencies will sometimes register even in the bytearray.position = 0 float. Is this a problem with the design of the computeSpectrum class? Because I can take the same file, put it in another spectrum analyzer and see the bass and treble spread more evenly.[URL]

Since there's (obviously) only one instance of SoundMixer in any given file, is it not possible to run computeSpectrum discreetly on different soundfiles loaded into an application? Basically I want to visualise each sound differently. Anyone come across any workarounds?
View 4 RepliesFor the past couple of weeks I've been wracking my brains over SoundMixer.computeSpectrum(), arguably the coolest method in ActionScript 3. It's the one that spits out the last 256 (or so) audio samples that hit the speakers, with the option of viewing that data in the time domain (waveform) or the frequency domain (Fourier transform). It's great for visualizing music, but its major drawback is that it only operates on global, playing audio, which means you cannot visualize different channels or preprocess the visualization.
Sound.extract(), a new method in Flash Player 10, gives you a Sound object's entire waveform at any time you want; I've managed to line up the waveform in Sound.extract() perfectly with the waveform in SoundMixer.computeSpectrum(), so they are literally neck-in-neck. In this SWF I'm drawing two lines- a blue line, which uses data from SoundMixer.computeSpectrum(), and a red line, which uses data from

View 4 RepliesI have a Flex3 app I wrote and I'm streaming audio over RTMP from a Red5 server. I'd love to be able to use SoundMixer.computeSpectrum(), but the spectrum data is all zeros. In one location, Adobe writes that SoundMixer.computeSpectrum() does not work with RTMP data:
"For media loaded from RTMP sources, you cannot use the BitmapData.draw() and SoundMixer.computeSpectrum() methods to extract run-time graphics and sound data." [URL] Clear enough. Except, there's the actual documentation for computeSpectrum(): "In addition, this method cannot be used to extract data from RTMP streams, even when it is called by content that reside in the same domain as the RTMP server. [...] This method is supported over RTMP in Flash Player 9.0.115.0 and later and in Adobe AIR."

I am executing a computeSpectrum function every 1/10 of a second (the speed I should be sampling the sound frequency to obtain a data bit). However the computeSpectrum seems to be giving me the same output every two or three times I call it.
Take a look at the source code and check the Binary read. Notice the binary read is repeating numbers, and the lack of single '0' or '1' bits? There should be some single '0's and '1's in there! I even made arrays of all of the input to check if the uncompressed ByteArray data was repeating and sure enough, the samples were quite often IDENTICAL every 2 or 3 calls...
PS: The audio sample data [More audio samples available there] I'm using is Peceptive Development's 'How to talk to Tin Can' [More info on reading audio as data there]. The audio sample provided in the archive is 'Low speed', which means the data is being sent at 100 baud (100 baud / 1000 ms = 10 bits per second)
I was wondering if it is possible to analyze music playing on a user's computer and show visualizations of it using computerSpectrum? Basically, can Flash read the audio playing on a computer or just the user's microphone?
