The Mastering Show #90 - Inter-sample peaks and True Peak limiting - the devilish details
The Mastering Show - En podkast av Ian Shepherd

Everyone is talking about inter-sample peaks and True Peak limiters - or in fact it’s more accurate to say they’re arguing about whether ISPs are audible or not, and whether True Peak limiters sound bad ! In this episode I’m joined by Alexey Lukin, iZotope’s “godfather of RX”, to talk in detail about exactly what ISPs are and why they’re so confusing - including: * How are inter-sample peaks measured, and why do you see different results with different meters ? * What are DSP overshoot peaks, and how are they different ? * What does over-sampling have to do with all this, and why is it important ? * Do True Peak limiters really sound bad, and how should we test them ? * Why will they NOT prevent lossy decoder clipping, sometimes ? And * What the hell are we supposed to do about all this ?!?
