ActionScript 3.0 :: Sound Extract - ByteArray To Decibel?
Jun 29, 2010When I extract the bytearray of a sound file I get the raw audio data. Is it possible from that raw audio data to get the decibels?

ActionScript 3.0 :: WAV File - New Sound.extract() Function To Get Two Seconds Of A Sound Into A ByteArray
Nov 11, 2009I'm having some trouble getting the following code to work - trying to use the new Sound.extract() function to get two seconds of a Sound into a ByteArray, and then create a new bytearray with a WAV header, and then output the file. The resulting 'test.wav' file sounds very wrong although slightly recognisable? I think I may have some of the WAV header settings may be wrong but I'm not quite sure what's the matter and after a long time scratching

Flash :: Sound Extract To Bytearray - Progress Handler?
Mar 17, 2011I'm using the following to extract the sound data from a sound object and store this in a byte array.
I require that the entire mp3 be loaded into the bytearray before advancing and the below works fine for this purpose however flash temporarily hangs while it extracts this data (2.4mb mp3)
Is there a way i can stop it from hanging i.e. use an eventlistener to check the progress of the extract process?

Actionscript 3 :: Introduce A Sound From The Library To A ByteArray (and Then Play That ByteArray)?
Feb 16, 2011I am working on a game, made with Flash (using AS3) The game has a fast ball and when this ball hits an object it has to make a sound... but the sound starts with delay (so the ball is far away when the sound is played).This sound is edited by me and it hasn't got any silences at the beginning.The method i'm currently using is the simplest one:
public var sonidoPuntos1:sonidopunto1 = new sonidopunto1()
and then...
sonidoPuntos1.play()
I am trying to introduce the file into a ByteArray and then playing it from there...
Actionscript 3 :: Sound.extract Method Empties Sound Object Data
May 20, 2011I am using the following to extract the byte info from a sound object - however if I go back to the same sound object and run this again, The byteArray has no bytes available.
var data:ByteArray = new ByteArray;
sound.extract(data,sound.length*44.1);
data.position = 0;
return data;
Is this the correct behavior? Is there not a way to do this multiple times on the same sound object?
Flash :: Playing Sound From Data Acquired From Sound.extract()?
Aug 1, 2011I'm trying to play a sound using a technique found here (play the sound by sampling raw sound data gathered from the original with extract()), with the difference that the mp3 sound is embedded in the swf, not loaded externally. This is my code:
var soundBytes:ByteArray = new ByteArray();
var mp3sound:Sound = Sound(new Sound1_design()); // this is the embedded sound
mp3sound.extract(soundBytes, int.MAX_VALUE);

This works, in a way, except that the resulting sound is distorted (it has a kind of a metallic ring).
Flash :: Extract Sound From A Fla?
Jan 30, 2010There is an .fla file that has a sound wave in it's library. However I do not have this sound wave saved on my computer so I can not edit or open this sound in another application. I was wanting to know if its possible to extract this *.wav file from out of the fla library? I did some research and they said to goto export movie and export it as an *.wav file. However I tried this it exported the whole fla file as one big *.wav dud. I tried to play it and nothing happened which makes sense.

View 6 RepliesFlash - Flex Sound Extract And Save Mp3?
Aug 15, 2011I'm trying to rig up a basic mp3 cutter in Flash (using the Flex framework)I have gotten so far:
var ba:ByteArray=new ByteArray();
sound.extract(ba, playEnd - playStart, playStart);
This extracts the relevant bytes from the sound object and stores them in ba Then, I do this:
saveFile=new FileReference();
saveFile.save(ba, sound.id3.artist + " - " + sound.id3.songName + ".mp3");
The file saves properly, but it can not be played (Players say it is corrupted) how I can create a valid mp3 file from the byteArray obtained after the extraction?
ActionScript 3.0 :: Sound.extract() On Streaming Audio?
Sep 8, 2010I'm picking up Flash and AS3 after working with AS1 a few years back. My first project is a mp3 player that is able to take an mp3 file, a start loop point, and an end loop point to loop the mp3 without any gaps or breaks in the sound.
blog.andre-michelle.com/2010/playback-mp3-loop-gapless
I found this page that got me started, and went off of that code. The resulting player works perfectly except for one fatal flaw. As far as I know, the mp3 file must be fully loaded to be able to use the Sound.extract method on it, this can take a while when the files are 3-4 MB, especially on slow connections. I want to be able to have the audio start playing as soon as the mp3 file begins loading.Is there any way to use the Sound.extract method on a streaming audio file that has not fully loaded yet?
Actionscript 3.0 :: Music Visualization With Sound.extract()?
Mar 19, 2009I'm trying to match the behavior of SoundMixer.computeSpectrum() by using the new Sound.extract() method, so that I can draw music visualizations for separate Sound objects at once. As you know, computeSpectrum() samples the currently playing audio and copies it to a ByteArray. Sound.extract(), on the other hand, copies as much of the Sound as you want to the ByteArray, and does not require the Sound to be playing at the time.
With the Sound data extracted to a ByteArray, I know have about twenty-six thousand floating-point values representing the waveform, from start to finish. However, I'm only interested in about thirty-two of them at a time- the last thirty-two that were played. How do I determine where in the ByteArray that would be?

View 2 RepliesAS3 :: Flash - Sound.extract() - Create A Visual Waveform For An MP3
May 29, 2011I'm trying to create a visual waveform for an MP3. The code I've included is called on successful load of the MP3. I intend to extract just a few important samples from the sound to create the waveform, rather than extract the entire sound into a bytearray. Even on a good machine, extracting an entire song can cause flash to freeze up for 3-5 seconds (or longer!). For my purposes, this isn't feasible.
Unfortunately, the code I've got below is failing to produce any numbers. If I extract the entire song it functions, but extraction of just the key points is giving me nothing. Does performing an extract make the remainder of the sound object invalid for future extracts? If so, is there some way around this that won't freeze flash for an extended period of time during the extract? Some important variables from the rest of the code:

Flash :: AS3 Using Sound.extract In A Loop To Analyse A Soundfile?
Aug 27, 2011From this AS3 code I expect 500 lines of trace outputs that contain "2048". But instead I get only some lines containing "2048". The rest of the traces print a "0" which shows me that the extract() method did not return any data.
Why is this the case? I would like to iterate through the soundfile with a specific amount of steps to extract 2048 bytes of the sound at the respective position. Extracting the entire soundfile at once would freeze the flashplayer for seconds and is therefore not a good solution for me.This behaviour can be found as long steps is smaller than samplesInSound/2048.The closer it comes to that value, the more lines with a "0" are printed compared to those with a 2048 in it.
var sound:Sound = new Sound();
sound.load(new URLRequest("soundfile.mp3"));
sound.addEventListener(Event.COMPLETE, soundLoaded);[code].....
I had the idea that the extracted part of the soundfile is cut out of the rest of the soundfile after extracting it (like at Actionscript 3 - Sound.extract method empties sound object data), so I tried out another for loop:
for(var i=0; i<samplesInSound - steps * 2048; i += Math.floor(samplesInSound/steps) - 2048) but this didn't work out either.

Jan 18, 2012I'm trying to prepend the byte array of a sound object to a captured microphone sound byte array.
It works, but the extracted sound object get pichted down and doubled in length. I guess this is because the byte array of the sound object is in stereo, while the mic byte array is in mono.
I have this:
sound.extract(myByteArray, extract);
myByteArray now contains the stereo data. How can I turn this to mono
UPDATE:
Here's a working solution:

I aligned them so you can see that the beginning is cut off and obviously the length is incorrect.
