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?
View 3 Repliesdoes anyone have an example of a simple volume slider that controls the master volume of the entire swf?
View 1 RepliesI've created a small music player with a sliding volume control. I'm having trouble with the volume. Though it does control volume properly, if I set the initial volume to less than 100%, the volume always starts at 100% until I move my mouse over the player. At that point, the volume changes to whatever the initial volume is set to.Is this a flash bug, or am I missing something? Here is the affected code (code for other buttons/functions omitted for brevity):
var song_initvolume:Number = 100;
slider_1._x = groove_1._x + song_initvolume;
playSong(0,song_play);[code]....
I'd like to be able to set the volume at say 50%, but the above mentioned behavior happens each time.
I'm building a video player and am kinda stuck at the volume slider part. It's a YouTube style vertical slider, meaning if the slider is in the top position volume should be 100% and if the slider is dragged to the bottom position sound should be 0. Currently it's doing the opposite of what I want :(
Dragging the slider down will make the sound louder, while dragging up lowers it.
Here is my code below dealing with the volume slider.
[Code]....
The (-4) is an offset value so when you drag it all the way to turn it off, it's 0 and not 4. I need to reverse this somehow, so the traces above will swap... going down will make userVolume = 4 and going up will make it 30.
I've got a serious of games which in turn load off a main main swf.I have mute and unmute buttons on the main menu and the same buttons in each game.When I unload/load a game I want the volume to stay as it is so they player doesn't have to keep turning the volume off. AudioOff is the button shown when the volume is off and AudioOn is the button shown when the volume is on.The code I've got now keeps the volume on or off through the games but the buttons aren't showing up correct with this code..
if (SoundVolume.volume == 1)
{
AudioOn.visible = false;[code].....
I converted the slider bar and slider button to buttons. Then, I made the slider button into a movie clip.
Here is the code I placed while slider button was a button:
Code:
on (press) {
startDrag(this, false, left, top, right, bottom);
}
[Code]....
It seems right to me but I don't know. The movie button slides down the slider bar but it just doesn't affect the volume. Going to try to attach my FLA to offer better insight. Just tried to upload it and no matter if it's FLA or zipped FLA, it says it failed.
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]

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?
View 6 RepliesI 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 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.

I wrote something to capture sound from my microphone. I can visualise the sound data with SoundMixer.computeSpectrum.is there a way to mute the sound and still get sound data from SoundMixer.computeSpectrum?Now I have this:

sc.soundTransform = t;
but I do not get any data. if I pump up the volume, data comes through again(I need to mute it because it will echo otherwise).

I have a tower defense game that I am working on and I'm in the process of adding sounds. Each tower plays its own fire sound when it fires. However When I have 5+ towers of the same type firing at the same time the volume gets louder.
Here is my game as is, the sounds are only in testing stage right now and I am aware that they can get annoying with the current set up.[URL]..
Most noticeably are the air towers. if you feel like listening play my game and first place 1 Air (blue) tower on screen. When the first air wave starts (lvl 4) hear the one tower firing alone and then during this stage add a 2nd tower and the volume almost, if not, doubles.
