From what I have read, using Speek over Nellymoser is advantageous, but I can't figure out how to use it with a Flex 4 Microphone object. For instance, the last code line:
[Code]...
With AIR 2 allowing access to mic data, it's possible to save/process audio locally. Adobe provides a WAVWriter example but is there any API access to the Speex codec?
View 1 RepliesPeople have figured out how to use the Google Speech API (Speech-To-Text). I'm trying to get it working with Flash Speex codec, and I just can't figure it out. I've tried inserting frame size byte before each 160 bytes (as some sources say), but this doesn't work. So I post a challenge to somehow translate the flash speex bytes for Google Speech API to understand. Here is basic flex code:

Codec = speex is too noisy: set noiseSuppressionLevel is no use.
But codec = Nellymoser is ok.
I want to play *.spx files which encoded by Speex on the Web.But I have no knowledge of Flash/Flex or any Flash Audio codec. After Google search for a whole day, I got some solutions, that is:
Do something wrapping Speex files with a FLV container because that the Speex is only playable as the audio codec in a FLV container.Now I can play a SPX-Audio-Only FLV file in Flex, I use netStream.play("audio-only-speex.flv"), But I donot know how to wrap a Spx file with FLV container using ActionScript.I have never heard FMS stuffs before, as well as I'm not sure whether my virtual host can support or not...Convert every Spx files to MP3.
I think the best solution is decoding Spx in AS3, Yes, I'd like to make a Spx Flash Player.So, I downloaded Speex Library from speex.org, installed Adobe Alchemy. After ./configure;make the libspeex, build libspeex/speex.c out a libspeex.swc via Alchemy. then, I donot know how to do next. How can I decode the speex audio with AS3? My libspeex.swc: [url].....
In addtion, should I rewrite the libspeex using Alchemy API before build the libspeex.swc? Although I am not professional in AS, but I have a strong ability to learn.
I am able to record sound from microphone, encode it using SPEEX and write into ByteArray. I want to play it back. If I try using Sound object the audio is messed up. Speex uses 16kHz for encoding and Sound Object needs 44.1kHz for playing audio. How am I supposed to play this encoded sound.
View 1 RepliesI'm implementing a very simple audio-only RTMP server.I have my client code like this:
// get the default mic
var mic:Microphone= Microphone.getMicrophone();
// best quality (picks up all sounds, no transmission interruptions)[code].....
Then on the server, I keep receiving audio packets with size of either 43 bytes or 11 bytes (no other sizes found yet).My questions are:
Why do I get size of either 43 bytes or 11 bytes (from SPEEX encoding?)?
Is the 43 bytes = 1 head byte + 42 data bytes?
What is the size of 11 bytes?
How should I process or convert the SPEEX to raw data, so that my server side app can use this audio data? My current implementation:
I pick up all 43-byte packets (drop all 11-byte packets);
Skip the first 1 byte;
Decode the left 42 bytes using Speex library.
How should I convert the raw data back to SPEEX audio data?
When i am pointing to an FlV it's playing successfully. But when it comes to a speex file. I am getting an error StreamnotFound. How to resolve this issue?
View 2 RepliesIs it possible to enable the user to resize an object in the flash movie?
What I want is a box for example, that can be dragged and dropped but also resized both vertically and horizontally. For example the user is able to drag the bounds of the box in a direction thereby making the box bigger or smaller. The mouse should also change to tell the user that he/she is enabled to do so.
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].....
I'm stuck on making an object move via sound inputted from the Microphone. I've done this at the moment.
[Code]....
i have the actionscript to allow an object to be manipulated by the sound received in the microphone:
m = Microphone.get();
attachAudio(m);
m.setUseEchoSuppression(false);
onEnterFrame = function () {
circle._xscale = circle._yscale = m.activityLevel+50;
};
but i need the script to allow the function that when sound is made it triggers a jump to a different frame.
As mentioned in release notes to Flash Player 11, developers added LZMA compression support.
Question is how can one enable this support? Maybe there's an mxmlc option? Or more steps?
Simply setting -swf-version=13 and switching playerglobal.swc in sdk didn't work for me.
Adobe's "SWF File Format Specification v10" says that Speex encoded data can be used for streaming sound (a little clarification of the "streaming sound" definition here: "The SWF file format supports a streaming sound mode where sound data is played and downloaded in tight synchronization with the timeline. In this mode, sound packets are stored with each frame." - this has nothing to do with any FMS streaming, no ActionScript needed - just plain SWF).This should be accomplished by using a single SoundStreamHead2 tag with StreamSoundCompression set to 11 (which means "Speex", as stated in the abovementioned Specification) and then N pairs of ShowFrame and SoundStreamBlock tags. However, this does not work - Flash Player plays no sound when playing the SWF generated by me this way. Please note, that I am capable of generating such SWFs containing streamed MP3 or PCM data, which then play perfectly. Just not Speex...
I strictly conform to the Specification:URL...I tried the streaming sound approach as well as the event sound - both do not work.Moreover, I was not able to find (anywhere on the Internet) any sample SWF with streaming sound (nor event sound) encoded in Speex. Do they even exist? Anyway, Flash CS5.5 is not capable of generating them.I would just like to know whether Speex support for SWF streaming sound can be found anywhere else than in the Specification. (I know that FLV can contain Speex and that Flash Player can stream Speex from a microphone and that FMS can stream Speex to its clients, but this is not what I am asking for)
could you answer whether ScreenVideo codec (ID=3) is supported by latest FlashPlayer for DefineVideoStream/VideoFrame tags?
View 1 RepliesI have tried really hard to find an example showing how to play speex encoded audio in flash. I tried the following code -
var connect_nc:NetConnection = new NetConnection();
connect_nc.connect(null);
var stream_ns:NetStream = new NetStream(connect_nc);
[Code]....
I tested the above code with .flv videos and AAC encoded audio files and it works just fine. But when I try stream_ns.play("sample.spx") I get a stream not found exception.
Am I using the wrong container (.spx) for speex audio. Is playing speex audio from a file supported?

View 3 RepliesI use Red5 server 0.9.1 for live streaming from Adobe Flash player to my RTMP protocol transport.I test it with audio data captured from my microphone using flash application and for now transport recieves and recognizes audio packets. For further audio data listening I need to know what audio codec Flash player uses to send data to the Red5 server.Transport doesn't recieve any metadata packets with detailed information about media codec. All I know for now from "connect" message is that publishing side supports the set of audio and video codecs.

View 1 RepliesRight now I am working on an AIR 3.2 application which lets you stream a video to a Flash Media Server and saves it on a hard drive.This sequence works fine with the standard Sorenson codec but I want to use H.264 for my videos. I found lots example c ode and implemented it in my code, but when I record a video of myself I am unable to re-watch it afterwards.I found how to implement a H.264 encoding in a realeyes blog post here. My code is here.It saves the video as a .f4v file, but my browser (I've tried the latest versions of both Chrome and Firefox, with the latest Flash) and also VLC are unable to load the video. I also used a program called Movie Player which is able to open the file but can only show the first frame and the audio. Neither am I able to upload the video to YouTube because they do not support the file extension.Here is an example video file it saved: H264Test1.f4v.My question is: How do I stream and save the movie with a file extension that I am able to re-watch while using the H.264 codec?
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 need the Remote Shared Object functionality and wonder if Flash Media Streaming Server incorporates this functionality?
View 1 RepliesI was looking around sites for navigation, and came across this: [URL]. I really like the way the menu with the four to five movies that scroll to the left and when hovering over them, the one you chose expands, pushes the other ones to the right of it away, and shows a description, stopping the movement. I'm thinking that this is partially the same concept as the infinite scroller, but how did they enable the object to "push" the other objects away? Tween class? [URL]
