Hi Tristan, I need a vi to take a waveform, typicaly 200 scans over 1.5 secs, and provide a smoothing/weighting action to join the start and end of the wave. Waves will be played as a loop and provide continuous walking for a biped robot. That is why it is important to smooth/join the start/end. I also need to minimise the effect of the vi on the wave and would like the function to affect as few start/end samples as possible. I have tried looking through some of the filtering vi's but dont have any electronic filtering experience. The vi should not introduce and high frequency bumps at the joining point as the windowed data will be experiemented on using other functions like polynomial, fourier etc. I imagine the solution will split the wave data into 3 different sections: 1, 1st 10 scans of adjusted data. 2, roughly 180 scans of untouched data. 3, last 10 scans of adjusted data. Please let me know if you require more info. Regards Chris
