ActionScript3.0で音声合成プログラミング

ActionScriptで何とか音を合成して鳴らしてみようと思ってしまいました。
そこで、調べてみました。
すると、どうも、簡単には出来ないことが分かりました。
原因は、ByteArrayから読み込みが出来ないからです。
これはやるしかないってことでやってみました。

flex2のコンパイラであるmxmlcをハックして何とかできました。

方針

①無圧縮の音声データを含んだMovieClipを作る。
②無圧縮の音声データを含んだMovieClipをByteArrayに入れる。
③音声データ部分を書き換える。
④ByteArrayからLoader.loadBytesを使って読み込み再生する。

と言う感じです。
さて、問題は無圧縮音声データを持ったのMovieClipをどうやって作るかです。
mxmlcでは、[embeded soruce="data.mp3"]
のように書くことで、ムービークリップ内にデータを取り込むことができるのですが、
wavファイルを指定しても対応していないので読み込んでくれません。
幸い、mxmlcはjavaで出来ています。
そこで、mxmlcを改造して読み込めるようにします。

やりかた

①mp3の文字列を含むjarファイルを探す。
mxmlc.jarに特に目をつける。
②mxmlc.jarを解凍して
mp3を含むファイルを検索する。

SoundTranscoder$NotInMP3Format.class
SoundTranscoder.class
MimeMappings.class

が見つかる。

ディスコンパイルする。

MimeMappings.java内の

set( "image/svg", new String[] { ".svg", ".svgz" } );
set( "audio/mpeg", ".mp3" );
set( "application/x-shockwave-flash", ".swf" );

とあるところに、

set( "audio/wav", ".wav" );
を追加する。

SoundTranscoder.java内に
mp3読み込み部分を改造してwavを読み込めるようにする。
(11025hzの無圧縮のみ対応してます)

public SoundTranscoder() {
	super(new String {
		"audio/mpeg",
		"audio/wav",
	}, flash.swf.tags.DefineSound.class, true);
}

：
：

	private DefineSound mp3(VirtualFile source, String symbolName)
		throws TranscoderException
	{
		String location = source.getName();
		InputStream in = null;
		byte sound = null;
		try
		{
			int size = (int)source.size();
			in = source.getInputStream();

			int b;
			if( ( b = in.read() ) == -1) throw new IOException();
			if(b == 'R') {
				sound = readWav(in, size-1);
				DefineSound ds = new DefineSound();
				ds.format = 3;// uncompress
				ds.data = sound;
				ds.size = 1;
				ds.name = symbolName;
				ds.rate = 1;// 11025
				ds.type = 0;// mono;
				ds.sampleCount = sound.length/2;
				return ds;
			} else {
				sound = readFully(in, size-1);
			}

：
：
：

	private byte[] readWav(InputStream inputStream, int size)
		throws IOException
	{
		BufferedInputStream in = new BufferedInputStream(inputStream);
		ByteArrayOutputStream baos = new ByteArrayOutputStream(size + 2);
		baos.write(0);
		baos.write(0);
		int state = 0;
		do
		{
			int b;
			if( ( b = in.read() ) == -1)
				break;
			switch(state){
			case 0:
				if(b == 'd') state = 1;
				break;
			case 1:
				if(b == 'a') state = 2;
				else state = 0;
				break;
			case 2:
				if(b == 't') state = 3;
				else state = 0;
				break;
			case 3:
				if(b == 'a') {
					state = 4;
					in.read();
					in.read();
					in.read();
					in.read();
				} else state = 0;
				break;
			case 4:
				baos.write(b);
				break;
			}
		} while(true);
		return baos.toByteArray();
	}

として、やったらできました。
で、コンパイルして、jarにぶっこみます。

あとは、asをコンパイル実行して上手くいくかなと？
swfをじっこうしてみます。
音が鳴れば成功です。

package {
	import flash.display.*;
	import flash.events.*;
	import flash.net.*;
	import flash.utils.*;
	import flash.media.*;
	import mx.core.*;
	public class s2 extends Sprite {
		[Bindable]
		[Embed(source="short.wav")]
		private var c:Class;
		public var b:SoundAsset;
		public function s2() { b = SoundAsset(new c());
b.play();}
	}
}

さて、mxmlcでコンパイルしたデータは基本的にzipのアルゴリズムで圧縮されてます。なので、そこらへんからperlのプログラムを拾ってきて解凍したバージョンにします。

#!/usr/bin/perl

use Compress::Zlib;

$in = STDIN;
binmode STDIN;
binmode STDOUT;
read $in,$header,8;

die 'not CWS' if $header !~ /^CWS/;

undef $/; # enable slurp mode
$buffer = <$in>;

#$buffer = compress($buffer) ;
$buffer = uncompress($buffer) ;
$header =~ s/^C/F/;

$out = STDOUT;
print $out $header;
print $out $buffer;

こんなのです。
で、適当に、配列に読み込めるデータとして吐き出します。

import std.file;

void main() {
	char dt = cast(char)read("short.swf");
	for(int i=0;i< dt.length;i++) {
		printf("0x%02X,", dt[i]);
		if (i % 16 == 7) printf(" ");
		if (i % 16 == 15) printf(" // %02X\n", i / 16);
	}
}

音がなってたものを、埋め込んだだけで、ならないようにしてこのプログラムの出力をas3に埋め込んで、アレコレするのが以下のas3ソースです。

package {
	import flash.media.*;
	import flash.display.*;
	import flash.events.*;
	import flash.net.*;
	import flash.utils.*;
	import mx.core.*;
	public class s extends Sprite {

		public function s() {
			var dt:Array=[

で、問題は音が鳴りはじめるタイミングが分からないというか、
1024byteのバッファがあるらしく、それに読み込むタイミングで鳴り出すようなのだけど、そのバッファに触れないのでレロレロなってしまいます。なったりならなかったり、２回分を１回でならしてみたり、、、。困った。

ってことで、とにかくここまでは出来たので報告しておく次第です。
