I often "speed up" the playback of large recordings by adjusting the throttle only. In the throttle block, I just multiple the recorded sample rate by a factor (say 10) to get increased playback speed. Don't change any other blocks' parameters - just the throttle. Very Respectfully, Dan CaJacob

Tom: What would you recommend if my data was recorded at 50M for about 15 seconds and I would like to double to playback time with a throttle. If I set the throttle to 25M, would that do the trick, or is it more complicated than that? I'm waiting for a new shipment of RAM, and once I have that I w
