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 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=son.play();
var t:SoundTransform = new SoundTransform(0, 0);
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 some sounds in my library. They are all exported and have been given class names like C, D, E etc. I have another class that represents a button. This class stores a reference to one of the Sound in my library. I set the type for this variable to Sound. When I try to set it I get the error: cannot convert C$ to flash.media.Sound I try as Sound, for example key.note = note_array[p] as Sound; The value ends up as null.
View 2 RepliesI use this class as a base for all my streaming sound. It gives you two missing properties not available in the Sound class: a reliable soundchannel always available for referencing and a latency value indicating how long it took for your last call to play() to actually play the sound. I'll probably post it on my blog when I get the time but here it is:

There must be a simple solution to stop the sound and unload it in as3.
This is not all of my code, but in short I am loading random sounds. I need certian vars to be outside of the function so I can reference them with other functions for a progress bar.
How do I unload a sound so I can load a new one using the same names without getting an error the second time its called?
I have two buttons in this test. A play Sound and a Stop Sound Button.
here is my code:
var TheSound:Sound = new Sound();
var mySoundChannel:SoundChannel = new SoundChannel();
PlayButton.addEventListener(MouseEvent.CLICK, PlaySound);

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]
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?

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 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 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 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.

When the timeline jumps to the page frame, the background music stops but the page's music doesn't start.
