During digital recording, music signals are sampled and then quantised to create the binary code that represents the amplitude of each sample in time. However, if the highest digital values are then normalised close to 0.0dBFs, then it’s entirely possible that a DAC’s oversampling filter will reconstruct signal peaks between samples that notionally exceed 0.0dBFs. It’s important to appreciate that the digital data is not ‘clipped’ but that in the process of upsampling this data, signals are realised that lie above this digital glass ceiling, beyond which is a netherworld of catastrophic clipping and momentary bursts of distortion. Of course, if the interpolator is designed with a few dB of headroom in tow – as is the case with MBL’s ‘True Peak Technology’ – then these peaks, known as ‘intersample overs’, are carried through without clipping.
