我試圖在我的動作項目中將wav轉換爲mp3，我很高興找到https://github.com/phillockwood/Shine-MP3-Encoder-on-AS3-Alchemy 但我的動作知識非常有限，我不知道如何在我的項目中使用它。如何使用「Shine-MP3-Encoder-on-AS3-Alchemy」？
在我的項目，功能如下，ByteArray的數據轉換成WAV格式，我需要將WAV轉換成MP3。我知道用個服務式MP3編碼器可以做這個工作，但我不知道在哪裏把它放在我的項目，以及如何將它的功能...誰可以幫我嗎？我也很欣賞它~~
public static function convertToWav(soundBytes:ByteArray, sampleRate:int):ByteArray {
var data:ByteArray = new ByteArray();
data.endian = Endian.LITTLE_ENDIAN;
var numBytes:uint = soundBytes.length/2; // soundBytes are 32bit floats, we are storing 16bit integers
var numChannels:int = 1;
var bitsPerSample:int = 16;
// The following is from https://ccrma.stanford.edu/courses/422/projects/WaveFormat/
data.writeUTFBytes("RIFF"); // ChunkID
data.writeUnsignedInt(36 + numBytes); // ChunkSize
data.writeUTFBytes("WAVE"); // Format
data.writeUTFBytes("fmt "); // Subchunk1ID
data.writeUnsignedInt(16); // Subchunk1Size // 16 for PCM
data.writeShort(1); // AudioFormat 1 Mono, 2 Stereo (Microphone is mono)
data.writeShort(numChannels); // NumChannels
data.writeUnsignedInt(sampleRate); // SampleRate
data.writeUnsignedInt(sampleRate * numChannels * bitsPerSample/8); // ByteRate
data.writeShort(numChannels * bitsPerSample/8); // BlockAlign
data.writeShort(bitsPerSample); // BitsPerSample
data.writeUTFBytes("data"); // Subchunk2ID
data.writeUnsignedInt(numBytes); // Subchunk2Size
soundBytes.position = 0;
while(soundBytes.bytesAvailable > 0) {
var sample:Number = soundBytes.readFloat(); // The sample is stored as a sine wave, -1 to 1
var val:int = sample * 32768; // Convert to a 16bit integer
data.writeShort(val);
}
return data;
}
