what is the significance of the number in front of dB when using audio extraction tools?
Posted on 2010-04-10
Lately, I have been using CDex with great success in ripping some music cd's to mp3. While I understand the majority of what I am looking at, one thing which is not clear to me relates to dB. From what I understand, dB is a measure of sound waves if I am not mistaken. I noticed in the area of CDex called Peak Value, there is a number like -2.86dB=71%, the second track might be 0.00dB=100%, the third track might be -2.38dB=76%, and so forth. Basically, each track which goes through the extraction process has a dB value and a percentage.
With what has been presented here, I am interested in any interpretations which can be given for these numbers. While I am sure this is just trivial, it still would be nice to have an understanding of this. Perhaps it is some type of interference ratio which gives an indication of the audio quality of each track. Of course, this point is mere speculation on my part.
At any rate, any shared input to this question will be greatly appreciated.
