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 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]
View 4 RepliesI'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?

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

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)

View 2 RepliesI'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.

View 1 RepliesI have two flash files that I would like to play back to back in the same location on my site. I would like one to play, and then when it's done, I want the other to play in its location.
I googled around and read up on the loadmovie variable, which I thought that is what I needed, but it isn't working.
To start out, what I did was create a new flash file, then I inserted an image into the timeline on its own layer, converted it to a movie clip (named pic_mc), did a fadeout effect on that image, then I created a new layer, and on the frame directly after the image, I put the following:
Code:
loadMovie("/images/preferred-reseller-hosting-0001.swf", "pic_mc")
I then ran a test (ctrl+enter) and all I see is the fade out image, and not the other flash movie. I even uploaded the .swf to my site and tested it there in a real world situation, and it didn't work. It just fades the image out and restarts the movie.

However, what would be the best way to organise this? Each "TV" will have a different set of "Channels". Do I create each 'channel' and save them as seperate SWF files, or is it possible to have them all in one main file. I can then flick through each 'channel', which essentially unloads the current animation and loads the next one

View 2 RepliesI have 2 FLA files, a "menu.fla" and "game.fla"
In my "menu.fla" I create an object of my class:
var gameEngine:Engine = new Engine();
I click on a button in "menu.swf" to load my "game.swf" into the window...
I would like to know how can I use the "gameEngine" object in my "game.swf"?
Also, I have to code that runs on a "left-arrow" key-press in "menu.fla", but I also have some code running on a "left-arrow" key-press in "game.fla".
Once "game.swf" is loaded, and I press the "left-arrow" both the code from "menu.swf" and "game.swf" executes.. I only want the game.fla's "left-arrow" code to execute?
I also noticed that "game.swf" is basically layered over "menu.swf". Is there a more efficient way to load .swf files?
I'm still working on this project and it got literally huge... at least huge enough to consume all of my 3 GB RAM memory and crash my Adobe Flash CS4.

Basically I have a main swf file, inside it there's an image (let's say its instance name is "projects_btn") that should take me to "Projects.swf", and I want to click on an "x" sign (its instance name is "xSign_btn") inside Projects.swf that would take me back to the main swf file "Bnaider2.swf".
