How can I smoothen a sound signal (A) with a 3 msec window? Time points were assigned using the code "plot((0:length(data)-1)/44.1, data)"

I'm no audio expert but maybe you can use conv() or filter(). You just have to figure out how many elements long 3 ms is.

Number of samples in 3 milliseconds is:
n = round(sampleRate * 0.003);
Here it looks like the sample rate is 44100, so that will be approximately 132 samples.
