Trim Audio File

[Sudarshan Bisht]

I need to trim down size/duration  of an audio file, for example I have a 5
MB audio file and I want to create an audio file having only 1 MB of size or
60 seconds of duration.
So to do this I need to first decode original audio file
completely/partially and then encode the raw samples again until it reaches
1MB/60 sec.
Is there any other optimized way ?  For example playing with audio headers.
