In Android Studio,How can I get the data after sound change with the type of byte[]?  
Well,my data of input is byte[] & I need get output data with changed is byte[] too.  
Oh yeah！the length of output data must be equal to length of input data.It’s very import!  
So how can I do ?

Well,There is my code(Java Language):  
====== code start ======  
private byte[] doVoice(){  
AudioFrame frame = getAudioFrame();  
ByteBuffer byteBuffer = frame.getData();  
byte[] inputBuffer = new byte[byteBuffer.limit()];  
byte[] outputBuffer = new byte[byteBuffer.limit()];  
byteBuffer.get(inputBuffer);  
outputBuffer = VoiceTools.changeVoice(1, inputBuffer);  
return outputBuffer;   
}  
====== code end ======  
so,the data format of voice is byte[],and how could I to deal these data with FMOD?
