Bravo, Alexey and RBJ! Way over my head but I understand the gist: In layman’s terms, it’s possible to construct an artificial signal whose sample peak does not exceed 0 dBFS but whose true peak can be much much higher. Yet still I have no idea how Sequoia’s true peak algorithm found the applause to reach +11 dBTP. I haven’t lost any sleep over it, however 🙂
Another hint: The more distorted, bright and compressed the music you master, the greater the chance it will produce 0 dBFS+ signals and totally mess up the sound, especially once it gets to a codec.
