Getting Recorded Audio Frequency in J2ME

[satyarajasekhar]

Hi,
I am doing one application in J2ME which records audio spoken through microphone attached to the phone.
I had to get the frequency in which the audio is recording from my application. I had gone through the
J2ME documentation for Player as well as RecordControl, but i couldn't find any information on
retrieving the frequency at which the sound is playing.

You question is not quite clear to me - are you looking for the rate or frequency when you are recording the file or when playing it back?

If you want frequency of sound in Hz then it is actually not a single value but a series of values as a function of time.
You will have to calculate fourier transform of the sound samples which will give you frequency.
Read about this on wikipedia on how to calculate fourier transform and frequency graph...
