Why can true peak be higher than sample peak?
Digital samples describe points along a waveform. The reconstructed waveform can rise above those points between samples. True-peak measurement estimates these intersample peaks, while sample peak reads the largest stored sample.
Leave room for the next export
Encoding and playback can change peak behavior. Check your final exported file, not only the mix inside your editor. If peaks are too high, lower the gain or use controlled limiting, then measure the new file again.
