DAW Sync and Automatic Re-metering.

Bute is compatible with VST / VST3 / AU and AAX (including Audio Suite) formats, so whether you use Pro Tools, Ableton, Logic, Cubase, Premiere Pro (or most other DAWs for that matter), Bute will synchronise with it. This integration allows for automatic re-metering, so when you listen back to any changes you made in your DAW, Bute automatically re-analyses too and updates the overall metering and history graph. 


All the presets.

When you are submitting work for multiple different platforms, it’s useful not to have to manually adjust your target levels. Bute offers a wide array of presets at your fingertips to save you the hassle. You can enter your own should you have any variations you need to use. We will continue to revise and update the presets as more standards are introduced and refined.

Fully compliant with the ITU-R BS.1770-1, ITU-R BS.1770-2, ITU-R BS.1770-3, EBU R128 standards, Spotify, YouTube, Apple Check, Hulu, Netflix, TIDAL, Sony Gaming (ASWG), AES Streaming Recommendation, US Public Radio (PRSS), TIDAL and Pandora.



History Overview & Custom Warning System.

The history overview and our custom warning system work in tandem to give you complete oversight and control of your session. The colour-coded custom warning system shows you areas of your audio that need your attention at a glance whilst the history overview gives you the ability to easily navigate and zoom around your session to these areas. You can adjust the target levels yourself in the settings.  Handling a long session? No problem!


Session Control.

Along with the ease of navigation the history overview offers, Bute is able to handle over 10 hours of data in one session and will reload metering data from previous sessions. You can also export metering data to prove compliance with loudness standards.


Easily Toggle Readings.

With its graphical user-interface, Bute offers an in-depth insight into your audio. To improve your workflow, you can toggle between relative and absolute loudness, short-term and momentary loudness, true-peak, and traditional RMS readings at the click of a button.


Flexible Interface.

Bute is very ergonomic. It’s completely scalable giving you the flexibility to adjust and integrate the it into your current workflow and save valuable screen space. Bute also updates in real-time for changes in visual settings.
