Audio clipping after render

So sounds good in the project, No distortion. Looks fine in the master audio, no peaking. And the waveforms look normal in the timeline. After rendering, the waveform clearly shows major clipping and there's distortion. Not doing anything out of the norm that I don't usually do in a project, any clues ?

They might lie in 'what you normally do!"

I can think of a few that have caught me by surprise until I thought it through. Applying Eq was one. All I used was low and high shelves, but these have a few dB gain at the corner frequency which caused a audio at those frequencies to be lifted in level and clipped.

Just one that comes to mind, would need a better idea of what you're doing first before ai could offer any more suggestion.

But wouldnt that show up peaking in the master when previewing ?

It seems that although the audio FXs are supposedly realtime they're not quite realtime, I've noticed that compression can show that I'm clipping quite a bit but when it's rendered the clipping isn't there. Same thing happened to me with Eq. It wasn't until I went to burn using CDA that it told me I'd clipped in a couple of places.

I guess the best solution is to make certain you've got a few dB headroom to start with or else open the track in SF and get it to run statistics over the whole track.
