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: Our guide shows you how to cleanly structure peak levels, headroom, and dynamics directly in the mix. 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.

How is true peak calculated?

The D/A conversion process, in which a digital signal is converted back into an analog signal for playback, can lead to slight level fluctuations. The analog reconstruction of the signal can have peaks well above the highest digital sample. In this case one speaks of 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 time segment is analyzed individually. When analyzing the audio signal, the audio signal is broken down into its individual frequencies. Each frequency of the audio signal is expressed by a specific level value. Then the level values ​​of all frequencies of the audio signal are compared with each other and the maximum level value 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 the distortions that can occur when the audio signal is digitized and played back. It is important to note that True Peak is not associated 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.
