I'm trying to build a play back progress bar for an audio recorded from the users microphone. It works okay but when I play back I can't figure out how long the audio is so I can calculate percent played for animating a progress bar. Most of these snippets can be found in LiveDocs and online examples from bytearray.org. Audio is stored in the bytearray and the sound is played back in a sound channel.

I want to limit server recorded netstream length to 10 secs at client side using as3. How can I do that?
View 2 RepliesI'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

I am trying to use the class Sound of actionscript.My code is really basic :
var snd:Sound = new Sound();
snd.load(new URLRequest("mysound.mp3"));
trace( new String(snd.length));
snd.play();
The audio is playing very well but in my trace, I get 0 instead of the length in milliseconds of the Sound.
I am trying to record a video chat being done through FMS. I have made my program start recording only when the second stream publishes. Then, I stop recording when either streams stops publishing. In my last test I recorded a 45 minute chat. The resulting flv files show that there are 13 seconds difference between them. The video gets more out of sync as it goes along. My first guess is that it is something to do with dropped frames. Is there any way to force FMS to fill in dropped frames. I'm posting my code for starting and stopping recording:

I 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...
My Flash movie has connected to a server via Socket. The server has sent some data over the Socket connection. This data consists of a 4-byte message header which describes the length of the incoming message and then the message itself. In this particular case, my message has a length of 500040 bytes.
My code receives the first installment of this long socket message in a block of 4,380 bytes. I know this because of trace statements in my socketDataHandler function. It peels off the 4 bytes at the beginning and interprets them to get the incoming message length of 500040. The remaining 4376 bytes go into a ByteArray var (a property of my class) called buffer. As more blocks of data arrive, the socketDataHandler function is repeatedly triggered and the extra blocks are concatenated into the buffer.

I'm trying to figure out how I can make the sound file that I load into Flash start at x seconds and end at x+30 seconds.So basically, I just want a 30 second sample to play starting at a specific time position. Does anyone have any advice on how to do this or have links to somewhere I can read up on it?

View 1 RepliesI need to mix 2 sound data, one is a mp3 sound byteArray and the other one is a recorded sound byteArray. I use URLLoader to load the mp3 external file into a byteArray. The sound is recorded on a microhpone and stored in another byteArray. I need to save to a file - the mp3 comes first and the recorded sound after. I am using WavWriter to write it out as a wav file.
The mp3 is in 44Khz and 16-bit rate. The recorded sound is in 44Khz and 8-bit.Is there a way to do this? I have researched for a few days already and tried a few things, but still cannot find the correct way to do this.
i am creating this little drum program, and the sounds is all done, all i need now is the ability to record what you play so you can play it back right afterwards.
View 1 RepliesYou could capture the sound into a ByteArray and save the bytes in a file or a database. Have a look at the SampleDataEvent on the Microphone class, and the ByteArray class. As for the php I think you want to look at mysql functions or fopen() and fwrite().
View 1 RepliesI just joined this Adobe Forums, and I am new to action script 3.0, I am working on a couple of lessons and I would like to be able to shorten the number of frames they take up on the timeline by setting the time the transition takes in seconds in my action script, and limiting each to a single frame so that my timeline can be organized and easy to work with.SO I set the seconds to 10 seconds, and kept each on a single key frame BUT THE PROBLEM is that the transition only plays as a single frame and cuts off and then moves to the next frame and so on

i have a slideshow with a delay of for example 3 seconds, and a preloader which is a line with a 100px final length.i start preloading next image.now if the time until next image loads is longer than slideshow delay, i will show next image as soon as it loads.if the time until next image loads is shorter that than slideshow delay, i want to wait additional time until delay and then show the image.the problem is how do i represent smooth line width grow (being enter frame or tween) by calculating/comparing 2 values together (delay and loader percent, which goes from 0 - 100) ?if my line growth represent just a slideshow delay, then when it gets to an end, if next image still hasnt loaded, then it wont look good if line has come to an end, but i still have to wait.
View 4 RepliesI'm trying to write the following 16bit WAV header data into a 16bit bytearray..? Using actionscript 3.
52 49 46 46 54 00 13 00 57 41 56 45 62 65 78 74 5A 02
What i'm doing is trying to pass the correct bytearray to this mp3 encoder (http://code.google.com/p/flash-kikko/) to get it to write out an mp3. If i use their example, i can open a 16bit WAV file via filereference and pass in that bytearray to the encoder to export an mp3... but i wanna create my own bytearray and pass it in and create the mp3. Using HxD, i copied the header and footer of that same 16bit WAV file and pasted it into flash as a bytearray but when i pass it into the encoder, it freezes the compile.. and i get the error: Error #1502: A script has executed for longer than the default timeout period of 15 seconds.

View 3 RepliesI'm trying to convert the byteArray of a Sound Object to an array with floats. The Sound Object plays back fine & at full length, but the float Array i get from it is cut off (but sounds correct), so i must be doing something wrong in the conversion:[code]The top two channels are the original Sound Object.The lower two is the float Array Data. I aligned them so you can see that the beginning is cut off and obviously the length is incorrect.
View 1 Repliesnormally the sound.length property is only accessibleafter the sound has finished downloading.I have heard there is an algorithm that can determine thesound.length property before an mp3 has finished downloading, or atleast approximate it very closely
View 1 Repliesdoing sound recording and playback in flash. I found this code from a tutorial and converted it to a flash document. From my traces, the record functions seem to be called. But when I try to play back the data, it tells me that the byteArray is empty. I've tested and I know that my microphone is working.
When I trace the size of the ByteArray, it returns 0;
So why does no data get recorded into the ByteArray?
output:

Stopped recording

View 2 RepliesI'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?

Problem is, soundFactory.length will return 0 ! That's because .length needs the entire file to be loaded in order to return the proper value, right ? If i trace it in "completeHandler" function, the right value is being shown but i cannot return the value to use it as a parameter in the "asteapta" function, at least i have no idea how. I guess i need to know the sound length before the file is being loaded.
I have a Flash based media player loading mp3s at 22.050 khz, and for some reason the length is being reported as a little over twice what it should be. Is there anything I can do, short of dividing the results by 2?
