How do you check peak output in LMMS?

This thread talks a lot about knowing your peak output: http://www.dubstepforum.com/viewtopic.p ... =moneyshot

I'm wondering, how can I check what the output levels (in decibels) are in LMMS?

Thank you for your help! :)
in your FX library you have a spectrum analyzer
you can monitor the dB for the channel you insert this analyzer in, and you can have spectrum analyzers on any instrument or channel -also Master.
- a more advanced alternative is the vst monitor SPAN
