BUTE Loudness Normaliser is a cross-platform application which assists the final checks of the mastering journey. With our automated solution, you can rest assured your audio is loudness-ready for broadcasting or streaming in just a few clicks, and won't be altered or rejected.

SIMPLY EFFECTIVE

It's incredibly easy to normalise your files using the BUTE Loudness Normaliser. Simply:

1) Drag in your WAV file.
2) Select one of the many presets, or set your custom parameters using our 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.
5) Save your finished file. Done.

Please note that the BUTE Loudness Normaliser offers in-depth analysis and normalisation of one track at a time. If you are looking for Batch Processing, check out our BUTE Batch Processor.

AUDIOPHILE QUALITY

Our advanced metering algorithm has been optimised to deliver superior sound quality and accurate results. The integrated True Peak limiter helps ensure there are no overshoots getting through, whilst still normalising to target. Our novel limiting algorithm also provides absolute transparency. Due to our 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.

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. We will keep these up-to-date and you can create and save your own presets as well.

Bute is fully compliant with all revisions of ITU-R BS. 1770, EBU R128, ATSC A/85, OP-59, ARIB TR-B32, Spotify, YouTube, Apple Check, Hulu, Netflix (including the latest revision), TIDAL, Sony Gaming (ASWG), AES Streaming Recommendation, US Public Radio (PRSS), TIDAL and Pandora.

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, our 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 our server-based enterprise solution is what you are looking for.

HIGH SPEED PROCESSING

We understand that loudness compliance can be a time critical task at the end of a project. Our high speed processing will meter, limit and normalise your audio in record time.

BUILT-IN TRUE PEAK LIMITER FOR PEACE OF MIND

Our 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

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

MEASURABLE PARAMETERS

See clearly laid out readings for overall integrated loudness, loudness range, short-term and momentary loudness, RMS and true-peak. These can be toggled on and off, so you only see the information you require.

FLEXIBLE AND SCALABLE

We give you the flexibility to adjust and integrate the Normaliser into your current work space. You can minimise it at the click of a button to divert your attention to other things.
