 | Hi, I tried to record an audio signal by speaking into a microphone using the audiorecorder object in Matlab 6.5. But the output was absolutely illegible,and was noisy. I tried the same thing with Microsoft Sound recorder and the signal was clear. Do I need to do some conditioning before using the audiorecorder object's output????

dunno MATLAB v 6.5, but you should be able to open your recorded .wav files with MATLAB, but that might be an additional inconvenient step.

 | yeah, i could open the recorded wav file using wavread().....but cant I record a clear audio signal directly into Matlab?

Presuming you used same parameters (Fs, NBITS, NCHANS), I guess it may be caused by the recording volume.
