No, you don’t have to treat or be aware of ISP but: Many of the top mastering business don’t care about ISP so why should I? In some extreme cases, the actual peak can be as much as 3-4dB above the sample peaks detected in the digital domain.
Just how bad this distortion depends on the converter used. In that process the newly created waveform may peak above the 0dBFS ceiling which individual samples adhere to, thereby causing distortion. No, Your D/A will create a waveform that continuously moves from one sample point to the next. That is, how your peaks will look after your waveform has been converted from a digital stream within your computer, phone, iPod or CD to electrical impulses that can be amplified and played back through your speakers.Īren’t the waveforms the same as they appear on my screen after the D/A conversion? ISP, Inter Sample Peak or TP, True Peak, refers to peaks in the analog domain.
