I'm making a audio recorder with Adobe Flex (Microphone, NetStream), I want to get the current audio wave from Microphone to display in the visualization area, how can i get the data?
View 1 RepliesA groups of friends are working on a little game that would listen to the microphone as part of the interaction. We've tinkered with processing and flex. What we'd like to know is if anyone has succeeded in:
recording from the microphone using a web app
performing an FFT on this microphone data
In the case of flex, according to the docs "Because sound data from a microphone...do not pass through the global SoundMixer object, the SoundMixer.computeSpectrum() method will not return data from those sources."[1]
I am unable to visualize the audio waveform in my flash timeline. I need to synchronize audio voiceover work and this is impossible to do without being able to see the timeline.
I am using CS4.....in previous versions I was able to see the waveform but no go for this version.....
I'm trying to create a WAV audio player for a website which will display the audio waveform like this site does: [URL]
Is there a way to do this? I've spent hours searching the internet with no luck.
I'm trying to stream *.wav files on a webpage and looking for a flash program which will show the full audio waveforms. Something like this:
How to do this? Again, streamings not the heard part, I just need to allow users to see the waveform timeline.
Is there a way to stream and audio line level feed rather than the audio from a computer's microphone?
View 1 RepliesI have got three screenshots below of Flash-based audio players on various websites that draw a waveform of the clip it is going to play and moves along while it is playing and also allowing the user to click on a point on the audio file and it jumps to that point.I have very little Flash knowledge but is this easy to achieve? I would like to just show the Flash file an mp3 and it draws the waveform. I understand this could be quite intensive on CPU so would there be a way of caching the waveform data so it doesn't redraw each time the file is loaded?
View 5 RepliesI am a newbie to this Flash Segment. Though for my recent project i am diving into it. I want to make "A Flash app which will Capture user voice from microphone. It can be appended if paused. After recording done i want to upload the file to the server. so that i can play it back when required." I tried this with java applet but the UI is too bad so i am thinking in respect to flash. What i found till now is for this i have to go for Flash Media Server which is not possible in my project. I want a simple player. You guys rocks that i can easily understand after some wondering in this forum but did not get my solution so thought of posting it.
View 1 RepliesI'd like to record audio from a microphone and I'd like the user to be able to add cue points during the recording so when he loads the file afterwards, he can jump easily to a specific position.
I don't really know what file format I should use and how to store the metadata (cue points)
I thought about
encoding a wav/mp3 and stores metadata in a .cue file (easy to do but 2 files to store)storing XMP data in a mp3 file (seems a bit harder but standard metadata embedded in 1 file)flv/f4v with audio only and standard cue points but I'm not sure I can create them directly from the client
I am having a problem trying to record internal sounds made from the flash file.I can record sound from the microphone no problem,What i want is to be able to record the sounds from the flash file without isung the microphone etc.

I have very little AS3 knowledge. I managed to connect to Mic, speak and hear my voice back. However, I am not sure how to stream this to PHP or rails server side.

View 1 RepliesIs it possible for Flash to detect the tempo of audio coming through the microphone (ex. - someone singing into the microphone or playing music on their computer)?I am trying to figure out whether this is possible.
View 2 RepliesIn Java there is a method of the AudioFormat called
getSampleRate
This returns the number of samples per second. I was wondering what the best way to achieve this with the microphone in flash is. I am not sure if I need to add a SamplesDatatEvent and use extract() or ?? I need to know the number of samples per second from the audio coming into the mic.
We need send h264 from flash to Wowza and after to vlc by RTSP protocol. But if we send sound in Speex codec, we not listens sound. what it is possible to make?
View 1 RepliesBasically I want to recreate a sound installation that I made a couple of months ago which used Logic Express and a Tape Delay effect to take ambient sound captured by a mic, delay its output by 3 seconds, and then play it into the headphones. All without recording anything and in realtime.I've basically got this far, which lets me hear the mic input through my headphones loud and clear. Now all I want to do is apply a 3 second delay to the input before it outputs. Do I have to send the audio to a buffer where it can be constantly stored and rewritten?
Code:
//Create a new Microphone
var mic:Microphone = Microphone.getMicrophone();

I'm setting up an application where I need to record users' voice every so often during the course of the users' interaction with the application. Recording is fine, and the quality is fine, but now my issue is understandng how Flash handles the microphone when it gets attached to a stream for publishing.Basically, the problem is that when I "publish" my stream, the voice gets cut off (clipped) at the beginning. So, I initially thought this may have to do with buffer settings on the FMS server side, but it wasn't. Then I investigated client side stuff. For some reason, my internal mic .activityLevel property is -1 even though I have called Microphone.getMicrophone(). According to Flash's documentation, this shouldn't be the case:
activityLevel propertyactivityLevel:Number [read-only]Language Version : ActionScript 3.0Player Version : Flash Player 9The amount of sound the microphone is detecting. Values range from 0 (no sound is detected) to 100 (very loud sound is detected). The value of this property can help you determine a good value to pass to the Microphone.setSilenceLevel() method.If the microphone is available but is not yet being used because Microphone.getMicrophone() has not been called, this property is set to -1.I am using a timer to investigate the microphone .activityLevel property every 50 milliseconds:
package
{
import fl.controls.Button;
import fl.controls.TextInput;[code].....

View 1 RepliesI have to detect avtivityLevel of microphone in Flex. I am using the activityLevel property of Microphone class but as I found out it always return -1 even if I have done Microphone.getMicrophone(). To detect activity level we have to set microphone.setLoopback = true;
how to do this without using loop back as I do not want to hear my sound back just monitor the activity level
i am trying to detect the microphone activity level. In windows XP, it's returing the activity level. But in windows vista, even if the mic is not connected it's returning an activity level. has anyone come across like this.what is the problem?
View 1 Repliesi am using red5 and flex. Actually my objective is to send microphone stream from the server to the client and play it on the client side. Similarly send microphone stream from client to server and play it on the server side. No need to store the live stream.

I am trying to create an audio watermarking system. I figure the best solution is to create an audio file (WAV) based on a unique string of text and then combine this with the original wav.The part that makes this tricky (for me anyway) is:How do I convert the text string to a wav?How do I ensure that the resulting WAV form is inaudible (or at least barely noticeable to the listener). would prefer this be done server side (via PHP, etc) but if the processing load isn't too much then would be ok with something in Flash or Javascript.
View 1 RepliesI've got a flash 10.1 app that lets me record microphone input to a wav without a media server, which I am saving to an Amazon S3 bucket.I have another process running on a server which gets wavs from this bucket, converts to mp3 using LAME and puts them into another bucket. This all works fine, but in converting wav > mp3, about 0.1sec or so of silence is added to my sound.In the application this are being used in, perfect sync is critical, so I need to trim off that little bit. If I have to trim it off the original waveform that is okay, I don't expect anything important to happen in that first fraction of a second.
What is the best way to go about this? I am using Adobe's WavWriter to convert by ByteArray into a proper waveform. Is there a way I can easily trim off the first few samples from my ByteArray without invalidating the structure?Alternatively, is there a good server-side tool I can use to trim the wav before running it through LAME, or an argument I can give LAME? Or, could I even trim that sound off the mp3 after it has been converted?
