What i am trying to do is to read from that C file, encode and thus
reconstruct the previous audio file. But i am getting noise.

and decoded a mp2 file (Could not answer to that thread because subscribed
after he answered. Sorry Mr. Tusher). But playing that decoded file, i am
getting previous sound with heavy noise. Can anybody tell me what is the
reason of it? To decode an audio file (mp2), is there any tutorial that i
can follow???

Hi tariqul islam,

You first try to use mono clip for your encoding and decoding purpose,  as
per your description I thnk your making mistake while reading data from the
buffers.  In example they hv given for single channel mono audio. Plz let
me know.
