ActionScript 3.0 :: Playing MIDI File - Any Way To Transform Into ByteArray?
Jan 14, 2010How can I play midi files in flash? Is there a way to transform into bytearray and play this?

View 4 RepliesI need to append MIDI files: leave header (same for all files) and other meta information, just copy music/score part. I already have MIDI files in appropriate bytearrays, as I guessed I need to use writeBytes, but unfortunately couldn't find which bytes I need to take and copy. Something like this:
var newFileBytes:ByteArray=new ByteArray();
newFileBytes.writeBytes(firstMIDIBytes);
newFileBytes.writeBytes(secondMIDIBytes,8);
Works only partially, file is playable; first part fully and second - only some notes (then player hangs out)
To say truth byteArrays aren't my strong side, as the MIDI file structure.
I want to load a midi file into Flash and have it read the sequence so I can get each musical note from the file.
But I'm not sure where to start on this. how I would go about accomplishing this?
Here is a site that has a pretty neat little flash object , [URL]
They let you upload a midi file and the recorder animation shows which positions on the flute/recorder you need to place your fingers at.
I'm just interested in how they used Flash to read the individual notes from the midi file.
I am reading midi files in as3 (flash cs5) with the help of the helpful library that is called midas [URL]- the midi-as3 library. I am trying to figure out a simple way to calculate the whole duration of the midi file (for example - total time of 4 minutes or 6 minutes...). I assume I could calculate the last note of each track + check the tempo and figure it out, but I was wondering if: Is the duration of the midi file is written somewhere in the data that I could just pull out and use?
View 1 RepliesI'm trying to write a simple sound recorder and am having trouble playing sound stored by using the sampledataevent trigger. My code is as follows:
Code:
import flash.display.Sprite;
import flash.media.Microphone;
import flash.events.*;
[Code].....
When the playFoReal function (sorry for the name!) is called no sound plays. I know my as is bad but I only started learning recently and really need to get this program working! There don't seem to be many examples to look at as I guess this technique is rather new.
if i will load my mp3 to bytearray and then play the bytearray it will beat the latency we have in playing sounds normally?
View 1 RepliesI could play MIDI file where "filename" is a String type with "asd.mid" value. However, I tried to sent AIR's nativeprocess command to Java, it shown "could not read" error.

I'm having trouble with loading in an external image that I can transform with the Senocular Transform Tool class. I have managed to load in the picture but the transform class doesn't seem want to grab it. Eventually I want to us the FileRef to upload the image but I just need to figure out how it works first. Here my code to load in the external image

The transform class can grab the other movieclips but it doesn't want to grab the new image loaded in from the code above.
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...
I have some animation (programmatic, I'm NOT using keyframed animation in timeline), and some music I want to play in the background. Once the music file reaches the end (about 30 seconds long), I want to trigger the end of the animation functions.I figure I could either use an actionscript timer to trigger the end of the animation or a keyframe with actionscript that is placed on the timeline near the end of the song but these methods assume knowledge about the duration of the wave file. If I changed the framerate or updated the external wave file, these triggers would possibly no longer sync upIs there some sort of event listener or other detection method for an audio file to signal it has finished playing? Or maybe there is a way to get the duration of the audio file to use in the timer
View 3 RepliesWell, i am recording the voice from heaphone and the sound data is stored in ByteArray at runtime, now can i stored as mp3 ?i want to save as mp3 file on the client system.. For that, i think i have to use air application..
View 1 RepliesI am coding an AIR application.
I've got directly a path of a swf file (because it was stored in a xml file). Do yo know if it is possible to get the ByteArray from this file ?
I know that FileReference do that very well, but this class need a select event. But it isn't my case because I've allready got my path.
There is a WSDL which have one method which take byteArray & fileName(which i want to write) as a parameter to write a file in local system, the following is the code...
public void writeLocation(byte[] byteToWrite, String fileName) throws FileNotFoundException
{
StringBuffer fileLocation = new StringBuffer("D:\Products\Device");
[Code]....
but the flex 2 showing the error when i searched i found out in flex 2 there is no "data" property. so i am unable to create the selected object into byteArray..
how to convert a file I have on my server (pdf/excel/ppt) to a ByteArray. The reason I want to do this is to display the dialogue open/save as to the user and I must set the Content-Type to octet-stream. The dialogue shows fine with just navigateToURL() but for pdf's it is the user's local browser setting. For a URLRequest I must set the data as a ByteArray. I'm trying to use the code located here:
Custom printing with Flex
I'm trying to download a file and convert it to ByteArray (it's a JPG file from a remote server if it matters).
View 1 RepliesI think I have a basic understanding of using bytearray and saving data to a local fileI've been able to save the data (strings) and bring them back.To start off, I have been teaching myself AS3. I have no knowledge of PHP or where to start with that. It has been said many times that you cannot make a txt file from within flash. Unfortunately this is what I need to do.I put together a map labelling app to use at work here. (it loads in a floor plan, then you can add 'nodes' that track info on each office - employee, ext, office #, data line jack, etc.) I would like to use this data in an access database that I have already running.in short, I would like to output my data from the mapper to CSV. On putting the data into a bytearray I am comfortable with marking the commas as well as line ends, but the data is not txt... is there a way to convert it
View 7 RepliesI m trying to write AS3 to take a screenshot of a MC thats on the stage and pass the data to a .cfc method which saves it as a jpg on the server.The current code I have kind of works except the jpg is unreadable.I think it has something to do with not using Flex, AMF, and writing binary files.When I look at the jpg via a hex viewer I think it doesnt have the right jpg header.The jpg begins with:c3 bf c3 98 c3 bf c3 a0 00 10 4a 46. When I think it should begin with:ff d8 ff e0 00 10 4a 46

How do i open file and get its content as a ByteArray in AS3. I saw examples, using FileStream & File classes from flex.filesystem, but the doc says it's for AIR only.
View 4 RepliesI need to write a ByteArray to a file on local disk with Flash AS3. The flashapplication is run locally (it's a projector exe).
I found the FileReference class with the save() function which works perfect. The only problem is, that this function opens a filebrowser and let's the user select where to store the file. However - i have the path already as string and need to save to this location without useraction (since i'm exporting a lot of files into this directory in one go and don't want the user to choose each one manually).
Is there a way to store a bytearray from a projector to local disk without opening a filebrowser?
I'm also using mdm Zinc, which actually provides a function to save a ByteArray to disk, but this function is for some unknown reasons not working. I already filed a bugreport, but I need to get this to work very urgently, so i'm looking for alternatives!
I read limited (small - 15 - 500 mb files). I need to be able to put all file bytes into one single bytearray. So I have a function:
[Bindable]
public var ba:ByteArray = new ByteArray;
//.... code ....//
[Code]....
But it does not work=( - gives me Error: Error #2030: End of file was encountered.
How to get a full bytearray from stream to use it as normal bytearray?
I have an Air application with remote service in codeigniter.I'm trying to save a bytearray that I received from the Air app but when I save the data I get empty files with the correct filename.So there must be something wrong with my bytearray or the way I save the data.Does anyone have an idea what I'm doing wrong?I've debugged the Arraycollection I sent and the bytearray is definitely in there.

I am using the FileReference object. I want to be able to save the local file data into a ByteArray. I know that I can use the data property in Flash 10, but I would like a solution that works for earlier versions of Flash.

View 2 RepliesI want to open a pdf/excel/doc using flex, as all know we can use navigateToUrl(URL) method to open a file from the server. But my problem is those files are encrypted in the server, so I load the files as follows
ByteLoader = new URLLoader();
ByteLoader.dataFormat = URLLoaderDataFormat.BINARY;
ByteLoader.load(new URLRequest (constructedURL));
so that I can manipulate them and can get the decrypted file. Now my question is, my data already got downloaded from the server, so how will I launch the files(pdf/doc/excel) with the binary content which I had got?
Is there anyway i can launch those files like we do it in navigateToURL()?
how to get this working.I have found that
writeByte(0xFF);
writeByte(0xFE);
At the beginning of the Byte Array alters the Encoding.How ever the resulting String using the toString method still creates escape characters.I am trying to write the byteArray to another AS3 file to be compiled later.
I would like to generate a sound in Adobe Air using ByteArray. The sound should be a silence of x seconds. I found this code that I am using to generate the bytes:
private function encode(data : ByteArray) : ByteArray
{
var channels : uint = 2;
var bits : uint = 16;

But when I save the file using Filereference and import it into a flash file I get an error message saying that there were problem reading the file.

View 7 RepliesI'm trying to figure out if it's possible to access a Midi device (like a piano/keyboard or electronic drum set) that is plugged into to a clients USB port over the web.
Obviously the browser security model makes this impossible using just javascript and while it looks like the emerging html5 device standard might help in the future it's apparently not there yet.
