 First of all you need open output file:

     outputFile = new QFile(fileName);
     outputFile->open(QIODevice::WriteOnly | QIODevice::Truncate);

 Then you need create encoder and attach output file to the encoder:

     encoder = new QCodec2Encoder(outputFile, this);
     encoder->setCodecMode(ui->cbBitrate->currentData().toInt());
     encoder->setNaturalEncoding(true);

 # Usage for playing voice
 First of all you need open output file:
 
+```
     audioInput = new QFile(m_WorkingFileName);

 Next you need create decoder:
