Audio sampling signals?

  1. Jul 5, 2011 #1
    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

    1. The problem statement, all variables and given/known data

    In digital transmission, what are audio sampling signals? What is the mimimum sampling rate required.
    2. Relevant equations



    3. The attempt at a solution

    "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.

    Sorry, I have not heard the term "audio sampling signals" before.
    I thought you were asking for help with sampling OF audio signals.
