Re: [android-developers] Re: how to convert morse sound to text???

android market has a application named morse code reader can convert morse sound to text...

The job of parsing Morse code can be very simple if the sound is clean
and regular.  If it is a little bit irregular in timing, then the job
gets harder.  If there is a little noise, then it gets harder still.
And if there is a lot of noise, then the programming becomes nearly
impossible.  The last I heard, a program could not beat a trained
human listener in the toughest of environments.  So how clean and
regular in timing is this Morse code that you want to parse.
