copied!<p>Done it! ( Well... almost :D )</p> <p>It was complicated but since my problem was only the audio of MovieClip I've created a class that acts like a mixer. </p> <p>The mixer is responsible to play all the sounds using a unique SampleDataEvent that mix the bytes of all my sounds. Also it generates a single sound data in ByteArray when i execute the startRecording funcion. Kind Complicated to explain but here is the code for the mixer:</p> <pre><code>/**** MySoundMixer initializations omitted ***/ //Generates the sound object to start the stream //for reproduce the mixed sounds. public function startStream() { fullStreamSound= new Sound(); fullStreamSoundData = new ByteArray(); this.fullStreamSoundChannel = this.fullStreamSound.play(); } //Adds a sound in the soundlib //(See: MySound object for more details) public function addSound(sound:MySound, key:String) { sound.initialize(); sounds.push({sound:sound, key:key}); } //Play a sound in the sound lib public function play(key) { var founded:MySound = null; for (var i = 0; i < sounds.length; i++) { if (key == sounds[i].key) { founded = sounds[i].sound; break; } } if (founded != null) { founded.play(); } } // The SampleDataEvent function to Play the sound and // if recording is activated record the sound to fullStreamSoundData public function processSampleData(event:SampleDataEvent) { var pos = 0; var normValue:Number = 1 / this.sounds.length; while (pos < BUFFER) { var leftChannel:Number = 0; var rightChannel:Number = 0; for (var i = 0; i < this.sounds.length; i++) { var currentSound:MySound = this.sounds[i].sound; var result = currentSound.getSampleData(); leftChannel += result.leftChannel * normValue; rightChannel += result.rightChannel * normValue; } event.data.writeFloat(leftChannel); event.data.writeFloat(rightChannel); if (isRecording) { fullStreamSoundData.writeFloat(leftChannel); fullStreamSoundData.writeFloat(rightChannel); } pos++; } } //Starts recording public function startRecording() { this.isRecording = true; } //Stops recording public function stopRecording() { this.isRecording = false; } </code></pre> <p>The SampleDataEvent is used for play and extract the mixed sounds at the same time.</p> <p>I also had to create a MySound class that extends the Sound object in order to extract the sampleData of each sound (method <strong>getSampleData()</strong>) at current buffer used by <strong>processSampleData</strong> method. The MySound class also starts playing when Mixer starts (sending 0 bytes for both channels) and will stop also when the mixer stops, it will only start to send the byte information of the music when <strong>play()</strong> function is called.</p> <p>The class that i have created is something like this:</p> <pre><code>/**** MySound initializations omitted ***/ public function initialize() { this.extractInformation(null); } //Override the play function to avoid playing. //(The play act will be triggered by SoundMixer class) override public function play(startTime:Number = 0, loops:int = 0, sndTransform:SoundTransform = null):SoundChannel { this.isPlaying = true; this.currentPhase = 0; return null; } // On each buffer in sampledata i read the chunk of sound bytes public function getSampleData() { var leftChannel:Number = 0; var rightChannel:Number = 0; if (this.isPlaying) { if (currentPhase < totalPhases) { this.soundData.position = currentPhase * 8; leftChannel = this.soundData.readFloat(); rightChannel = this.soundData.readFloat(); this.currentPhase ++; } else { stopPlaying(); } } return { leftChannel:leftChannel, rightChannel:rightChannel }; } //Extracts information of the sound object in order to //split it in several chunks of sounds. public function extractInformation(evt:Event) { trace("Inicializando o som " + this.id3); this.soundData = new ByteArray(); this.extract(soundData, int(this.length * SAMPLE_44HZ + 10000)); this.totalPhases = this.soundData.length / 8; this.currentPhase = 0; } ///Stop playing means stop extracting bytes public function stopPlaying() { this.isPlaying = false; } </code></pre> <p>With that, i have generated a unique ByteArray object that contains the hole sound information of the mixer. all i had to do is start the mixer when the movieclip starts and stop it also when the movieclip stops. The ByteArray information with the sound object is passed <strong>addFrame(bitmapData, sndData)</strong> of Alchemy Lib that records it successfully.</p> <p>It is working well in my project but i probably will need to optmize the code.</p> <p>Thanks all guys that helped me!</p>
