For those using Audacity who'd like to find the actual peaks within the waveforms quickly, you can Amplify>allow clipping>0.7 dB. You also have to ensure you have "show clipping" enabled under the

menu. Obviously set the level back when you're done. Also useful to import the same file to a second track directly below to actually work with, using the over amplified track as a reference.
