New Post: mixing audio received through serial port with a local audio file

Dear Sir,

I am getting audio file stream (as variable sized chunks per time eg 2000 bytes). I am saving this file to filewriter class

Private Mywriter As WaveFileWriter

and into the dataReceived event , I pass the audio chunk to wavefileriter class by Mywriter.Write

Question , :

• I have a local mp3 file in the same format at the received bytes (PCM,16 bit , 8000 HZ,mono).
• I will get the size of the received data , eg 2000 bytes, and will get the first 2000 bytes from the local file(same format)
• I need to get 2000 bytes that is mix between first 2000 bytes & second 2000 bytes.
• I will pass this 2000 bytes to the wavefilewriter.
  

How.

Thanks,
