True Peak
During mastering, True Peak determines whether an audio signal arrives at digital playback devices and streaming platforms without distortion. Unlike Sample Peak, True Peak also captures the Intersample peaks, which can occur during digital-to-analog conversion — which is why platforms like Spotify and Apple Music typically prescribe limits of −1 dBTP.
What is a true peak?
True peak is a measurement used to determine the actual maximum level of an audio signal. It is commonly used in recording studios and the professional music industry to ensure that audio signals don’t become too loud during playback on different devices, which could lead to distortion. Especially when online mastering Attention is paid to this value because it is of great importance for digital publication.
True Peak in a mixing context: How to already adjust peak levels, headroom, and dynamic range in Mix If you structure things cleanly, our Mixing Guide in the complete process overview.
True Peak is measured by analyzing the audio signal on a dedicated analysis device or in audio software. This takes into account not only the actual peak level of the audio signal, but also the distortions that can occur during digitization and playback. These distortions can cause the actual maximum audio signal level to be higher than the measured peak level, which is why True Peak is considered the more accurate measurement.
True Peak is often used to ensure that audio signals are suitable for broadcast on various playback devices such as radio, television, or music streaming services are optimally controlled.
Overall, True Peak is an important metric in professional practice. music section, which can help ensure that audio signals are reproduced cleanly and without distortion on various playback devices.

The D/A conversion processThe process of converting a digital signal back into an analog signal for playback can lead to slight level fluctuations. The analog reconstruction of the signal can exhibit peak values that are far higher than the highest digital sample value. This is referred to as a true peak or inter-sample peak.
True Peak is calculated by analyzing the audio signal on a special analyzer. The audio signal is divided into small time segments, and each segment is analyzed individually.
When analyzing an audio signal, the signal is broken down into its individual frequencies. Each frequency of the audio signal is then expressed by a specific level value.
The levels of all frequencies in the audio signal are then compared, and the maximum level is determined as the true peak of the audio signal. This true peak value indicates how loud the audio signal actually is and also takes into account any distortion that may occur during digitization and playback.
It is important to note that True Peak is not compatible with the peak level of the audio signal is identical. Peak level only indicates the current maximum audio signal level, while True Peak takes into account the actual maximum audio signal level that can occur when the audio signal is digitized and played back.
What is the ideal true peak value for mastering?
For streaming platforms, a true peak maximum of -1 dBTP is considered a safe recommendation to avoid distortion caused by inter-sample peaks and lossy codecs. Some mastering engineers take an even more conservative approach with -1,5 or -2 dBTP. It's important to measure the true peak with a suitable [tool/method - context needed]. measuring tool to control, not just the normal sample peak.
What is the difference between True Peak and LUFS?
True Peak measures the highest actual level of the analog reconstructed signal, while LUFS True Peak describes the perceived loudness over time. True Peak protects against clipping, while LUFS ensures consistent loudness. During mastering, both values are considered together – a target LUFS value for loudness and a True Peak limit to prevent clipping.
Why is True Peak important at all?
When converting a digital signal back to analog or compressing it into formats like MP3 and AAC, levels exceeding 0 dBFS can occur between samples – these are called inter-sample peaks. These lead to audible distortion, even though the normal level meter still appears "clean." True-peak metering makes these hidden peaks visible and thus protects the Sound quality before clipping.
