Hi all,
I want to log an 8 hour signal from a pcb mic. with the sound and vibration assistant(signal express). I want to acquire at 50KHz, but i think there wi'll be too much data. Is there a WAY to reduce that data?
thank you

HI Pollon,
what about averaging the signal in a certain amount of time, to reduce the number of points you have to save?
If for example you're acquiring at 50 Hz, you can save the mean value for every 50 points, and in that case, you're saving one point each second.
Hope it helps,
have a nice day!

There's a processing function called time averaging that does the average:
