am trying to make a mp3 player by using actionscript3.In this , am trying a upload a mp3 file and play that particular file. Am also using the computespectrum() to display the graphics.Now the problem am facing is with the computespectrum . Randomly , the computespectrum is failing for the same file and is throwing error.The error is as follows [code]Am actually uploading the file into a folder named "mp3files". The "mp3files" folder and the swf are lying in the same domain.
Using 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]
I'm building a media player with a sound visualizer using computeSpectrum(). When I adjust the volume, there is no longer any data for the visualizer. Does anyone know a way to adjust the volume of audio, but still access audio data using computeSpectrum() as if the sound were still audible?
Just wondering how often Flash (as3) will allow me to computeSpectrum? I am currently attempting to computeSpectrum 100 times per second, but I am finding that the data repeats every few times.
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?
For 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
I'm trying to do some beat detection on a sound, but I want other sounds playing at the same time, and I don't want those to be included in the beat detection. Is there anything like SoundMixer.computeSpectrum for individual Sound or SoundChannel instances ?
I managed to run my youtube api and SoundMixer.computeSpectrum.SoundMixer.computeSpectrum are online, positionBar, player.getDuration (), player.getCurrentTime () does not work.Everything is running on localhost.I do not know is the security issue,
I 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 have some arbitrary signal data which i'd like to get a frequency analysis of. it's not audio data. is there a way to coerce AS3's computeSpectrum() call into doing this work for me ?
I'm trying to use the code below to show a graphical representation of the sound from externally loaded FLVs, as they play.The code I have is below, can I change this to listen for whatever sounds Flash is playing at the moment and computeSpectrum from tha
Code: var url:String = "song.mp3"; var request:URLRequest = new URLRequest(url);
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?
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
I'm used to using SoundMixer.computeSpectrum, but I need to get some data on-the-fly from the microphone (and I can't use the SoundMixer with the microphone).
I'm having trouble translating the FFT data (from this class) as shown in this excellent spectral analysis example to match the ByteArray output from computeSpectrum. My existing code is built to handle the data received from computeSpectrum (with FFT set to true).
I'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.
I am trying to use if and else statements and failing. I am either completely missing their purpose, or just not writing the correct code. Scenario: I have designed a gallery that consists of animation in movie clips that are placed on the time line. With the if/else statements I need Flash to know what movie clip the user is on, so that the users next action loads the correct movie clip.
I've been manually creating a slideshow with flash (I like my final product better than the auto-approaches), and have reached a sort of odd situation.When trying to insert a new keyfram at fram 1675 of my animation, instead of a new keyframe, I'm getting my last keyframe's run (from 1650) extended to here.Is there a per-layer keyframe limit?And is there an FAQ that would cover this (fairly obvious seeming) question, rather than posting?
I made an XML file and then replicated that in a PHP file. I then just executed my PHP file and then viewed the source of it and then copied that into an XML file and had my AS read that file it works fine. However, when I have it set up to read my PHP file and I test it in Flash it gives me the following error:[code]
I am trying to develop a sound visualizer and i have developed OO solution but the problem is I get this error:

I have an ancient project that has thousands of lines of AS2 code spread out in class files. I started to try to make an on-screen keyboard and I noticed an issue with FP8 and the Selection class. I need to use FP8 because it's a MDM Zinc extended project and Zinc does not allow me to export to FP9 or FP10 if I use AS2.0. Of course this issue doesn't happen in FP9 or FP10.I have a reproducible example here that's highly simplified and stripped down. It has 3 class files, a Main, ExampleKeyboard and ExampleOutput. Main just instantiates the other 2 classes. The keyboard is all of 3 buttons (again very simplified to stick to the point). The output just generates an input TextField. This issue seems to be isolated to using the Selection class when your project has other classes. For mine, the keyboard is in one class and the TextField is drawn in another. I did a single frame no-class example and this problem does not exist so it's specific to the Selection methods using FP8 when a project contains classes. URL...After you run it you MUST press the red button to Selection.setFocus() the input field. The other 2 gray buttons simply send the letters 'a' and 'b' to the input text field. In FP9 and FP10 this all works just fine. The Selection. getCaratIndex() reports the cursors proper position (which I set every time you press a button). In FP8 you will see that Selection.getCaratIndex() ALWAYS returns -1. Has anyone had these Selection class issues in a project that used multiple classes and FP8?
So I have been able to generate random numbers before, but now they just seem to be spazzing out randomly.I created 4 dynamic textboxes with the variable names item1, item2, item3 and item4. The code that I have used on the frame is:
The main class shown below is showing a blank screen and is NOT navigating to [URL].

I am trying to create and build a flex library project (.swc) using maven 2 firsttime.I am able to create directory structure but build is failing. My maven settings are : Maven version : apache-maven-3.0.2
I have a Flex app that uses Flash Remoting and the RemoteObject to pull data from a ColdFusion CFC. About 75% of the time it works, but the other times I get a message using Charles (a debugging tool) that says faultString = "Unable to Invoke CFC". FaultCode = "Server.Processing".
