Simply Effective

It's incredibly easy to normalise your files using the Loudness Normaliser interface:

2) Select one of the many presets, or set your custom parameters using the application's unique system.

3) Hit "Analyse" and get an in-depth analysis with alerts to areas that require Bute's attention.

4) Click "Comply" to normalise your audio - the metering graph clearly shows the extent of true peak limiting.

Audiophile Quality

Signum Audio's advanced metering algorithm has been optimised to deliver superior sound quality and accurate results. The integrated true peak limiter provides absolute transparency and peace of mind that there are no overshoots getting through, whilst still normalising to target. Due to Signum Audio's approach, the relative dynamics of your audio will be affected as little as possible and you’ll be left with consistent, compliant masters of your audio files every single time. This makes it great as a final check for your mastering journey.

Features

Built-In Presets

By boasting a comprehensive range of industry standards and recommendations, the Bute Normaliser ensures that you can tune your productions to the needs of your clients with minimal effort. Signum Audio keep these up-to-date, and you can create and save your own presets as well.

Alert System

The colour-coded alert system notifies you if there are areas of your audio file that go out-with your desired target. You can see these areas in red on the history timeline. In addition, the application's custom alert system also allows you to finetune the alerts for all the readouts to your specific needs. These will appear in yellow.

Drag & Drop

Import and export your files with a simple drag & drop. Please note that the BUTE Normaliser only processes one file at a time. If you are looking for Batch Processing, then Signum Audio's server-based enterprise solution is what you are looking for.

High-Speed Processing

Signum Audio understand that loudness compliance can be a time critical task at the end of a project. The Loudness Normaliser's high speed processing will meter, limit and normalise your audio in record time.

Built-In True Peak Limiter for Peace of Mind

Signum Audio's novel design approach to the true peak limiter is an industry first, and it provides absolute transparency whilst ensuring no peak will ever go over the threshold. A gain reduction display shows you where and how much the limiter reduced your mix.

Import & Export in Multiple Formats

Signum Audio support the standard .WAV 42bit 48KHz for broadcasting with all its pull up and pull down variants. In addition, they also support .flac, .mp3, .aiff, and more.

Measurable Parameters
