Re: not enough memory to plot wav. file

I did not mean you should down-sample the signal.
Here is what you can do,
1) Pick 250 points,
2) Find max and min of these 250 points, append them to a Max Array and a Min Array.
3) Pick next 250 points
4) Repeat steps 2) and 3) until the end of the signal is reached.
5) plot out the Max and Min arrays at a sample rate of 1kHz, which is the envelop of your signal.
Hope this helps
