Audiorecorder in Matlab.....

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.
