2.1.6. Output type

---

The output type combo-box allows you to configure which type of metering measurement is displayed by the visualizer. These measurements are displayed using the current output color.

Integrated output type takes into consideration the full history of audio since last reset, and is implemented according to the LUFS specification.

History average, history peak, and history min are based on the history buffer, whose length is configurable from the visualization tab. This allows you to continuously analyze any length of time supported by the history length parameter.

Global average, global peak, and global min analyze all loudness measurements since the last reset.

PSR (peak-to-short-term loudness ratio) compares true peak against short-term LUFS, which makes it useful for spotting heavily limited passages and mix density changes.

PLR (peak-to-loudness ratio) compares true peak against Integrated LUFS for a program-level dynamic range summary.

Crest compares sample peak against RMS, which gives a traditional peak-to-average dynamic range view.
