# Audio sampling signals?

#### Googl

Hi,

I have a question and I was wondering whether you might help me, because I have done a lot of research nut no clues. Just bits and pieces.

Thanks ALOT

"Audio sampling" is converting an analog audio signal into digital data by measuring the signal level (voltage) frequently enough to capture the shape of the signal wave. The frequency range audible to the human ear is the major consideration. If you want to get 30 kHz sounds in your digital file, you must measure at a rate of at least 30 000 times a second (likely twice that for technical reasons). Check

for details.
