Bute Loudness Suite (Surround Version) by Signum Audio Review

Bute Loudness Suite qualifies you for the loudness war with an integrated solution containing an Analyser, a True Peak Limiter, and Normaliser. This suite provides you with the tool to measure and adjust the loudness depending on where you want to publish the track for example a streaming platform YouTube or TV.

Any sound professional worth their salt knows that audio is key in any project, but how that audio is mixed is just as crucial. Loudness standards play an important role in the success of a project, no matter to who the project is being delivered.

In order to maintain a dynamic mix that meets industry standards, Scotland-based Signum Audio has developed tools such as the Bute Loudness Analyser and Bute Loudness Normaliser to ensure compliance with streaming and broadcasting standards. The plugins are available separately or in a bundle called Bute Loudness Suite. With these tools at your disposal, you can rest assured that your mix will be compliant with all the necessary standards.

As any audio engineer knows, the sound is a complex phenomenon. In order to create a mix that sounds good on multiple devices and meets all the necessary compliance standards, it is essential to have a deep understanding of how sound works. Loudness normalization is one tool that can be used to help ensure that a mix sounds good on all types of speakers. By matching the loudness of the mix to the target specification, engineers can be confident that the mix will sound its best on any system.

However, it is important to note that loudness normalization should never be used as a substitute for meeting compliance standards at the mixing stage. In order to create a truly great mix, engineers need to understand both the science and art of sound.

There are many presets included to allow you to produce results for different platforms. Many of the needed target platforms and their loudness requirements are supported and can be extended later. Overall those presets are essential to produce with the target levels required for the platform you want to publish.

The presets fit with all revisions of ITU-R BS.1770 and fully support EBU R-128, ATSC A/85, OP-59, ARIB TR-B32, AGCOM 219/09/CSP, Public Radio (PRSS), expanded AES recommendation for streaming presets with a short form variant, added Sony Gaming preset for PS4 and PS Vita (ASWG).

The built-in limiter makes sure that the result does not clip. Instead of the built-in limiter, I may use an additional limiter I have. However, if you do not want to invest in a third-party limiter you are all set.

The most useful would be to use the tool as an AudioSuite plugin in Pro Tools, where you index one whole album to check if the overall loudness of all tracks is excellent, you can then normalize the entire album. This is very convenient and helps masters to produce. This is a Pro Tools-only function and will not work (yet) in other DAWs, but many do use Pro Tools for mastering, so it is a tremendous help for the mastering process.

The suite allows you to produce a consistent master where you reduce level shifting with the limiter you prevent clipping. The Surround version does also support ASWG 5.1 and 7.1 Surround Sound.

Bute Loudness Suite – User interface & Usability

When you start the suit the UI is pretty straightforward, to measure the signal you need to press play in your DAW – just playing in your software synthesizer or sample player will not “move the needle” or show anything. The reason for this is that the analyzer stores the track, this is excellent as you can jump back and forth on the track and make adjustments where needed.

The loudness graph is one of the most useful features of the interface. It shows you at a glance how your mixes are progressing, and it also allows you to make fine adjustments to the levels of individual tracks.

The best thing about it is that it uses an automatic re-metering system, so you don’t have to keep adjusting the levels manually. You can even set alerts for particular audio events, such as true peak levels or thresholds of short-term loudness. This means that you can make sure that your mixes are always sounding their best, without having to worry about making mistakes.

There is an integrated help system that jumps through the settings and explains them, instead of climbing through the possibilities an overview and overlayed help with pop-up help text would be for me more useful. The plugin can be switched into the compact mode, removing the analyzer section and only showing you the numbers.

Conclusion

While it’s self-evident that the most important tool for mixing is the human ear, it’s also true that the ear can be easily fooled. As a consequence it continues to be essential to support those critical listening skills with a reliable reference metering system: specifically, one that can analyze the ‘loudness’ of the material against the appropriate parameters for the various media streaming platforms that dominate the consumer music experience today.

The current loudness standards were developed with broadcast television in mind and are now being adopted by many online streaming services. This has led to a need for metering systems that can accurately measure against these new standards. In order to produce a mix that will sound its best on all platforms, it’s essential to have a metering system that can provide an accurate Loudness measurement.

Additionally, many modern metering systems also offer features such as True Peak measurement, which can be helpful in avoiding distortion on digital platforms. Whatever your budget or needs, make sure you invest in a good quality reference metering system to help you achieve professional results.

The Bute Loudness Suite by Signum Audio is an excellent tool for ensuring that your audio mixes are always sounding their best. It comes with a variety of presets that allow you to produce results for different platforms, and the built-in limiter ensures that your mixes don’t clip. The UI is straightforward and easy to use, andY NOW

the integrated help system is very helpful. Overall, the Bute Loudness Suite is a great tool for anyone who wants to produce professional-sounding audio mixes.
