Each of these 30 second samples are mastered to the clients’ requested Loudness and True Peak. So, they are anywhere from -10 to -14 LUFS Integrated and -.1 to -1.0 True Peak. We don’t believe there is any advantage in putting before and after samples, as usually the most distinguishing characteristic, if the mix is good, is loudness.
