Finding the maximum dB in an audio clip
I'm producing a DJ mix with Ableton. I'm very surprised to find that putting an MP3 or WAV into an audio track results in the master track going red, even though the the on the audio track and master are both 0dB. How can an audio file have a peak of more than 0dB in it?
Regardless, the only way I can find to stop this is to show the "peak level" control for each track on the session view, play the whole track and then use the peak value shown to adjust the clip volume or track volume such that the master never goes above 0dB.
So, my main question is how can I find that peak value without playing the whole track through a channel?
Is there something in the clip view I'm missing or is there some other utility (audicity? sound forge?) I can put an audio file through to tell me what that maximum value will be?
thanks for any help!
