We’re really excited to share the launch of our algorithmic online audio mastering tool which empowers everyone to create perfectly polished, radio-ready tracks. Fast, simple and most importantly – for FREE.

To musicians, mastering is an important step in the creative process that brings an audio mix to distribution-quality. When a song is played on a radio or streaming service, the sonic elements of the track have usually been finely balanced to ensure that everything is sounding its best.

Mastering is an important addition to our native creative toolset and integrates seamlessly throughout your workflow in the Mix Editor. Like our entire BandLab platform, this new service is 100% free for all users. Unlike other services, with our free online mastering tool there are no hidden charges, monthly fees, or limitations on quality, and most importantly – we don’t take any named-credits on your production notes.

Mastering Settings on BandLab

We designed BandLab mastering using cutting-edge modelling technology, paired with the work of the best mastering engineers from the BandLab community. We’ve developed emulations of classic mastering processors to accurately create an industry-standard audio signal-chain, including models of the vintage Aphex Aural Exciter™, detailed transient shaping through reel-to-reel tape emulators, a robust multi-band compressor, and a lightning-fast, discrete mastering limiter.

To achieve a high-quality, authentic mastered output, we analysed some of the best-mastered tracks in the world and used what we discovered to define parameters for our three unique settings. We’ve meticulously tested our mastering chains to ensure effectiveness at improving dynamic and spectral quality. The current three Mastering Settings on BandLab at time of the beta release are:

CD Quality Vector CD QUALITY: Incredibly versatile setting, boost the overall volume and polish of the track.

Bass Boost VectorBASS BOOST: Built for tracks that pack a punch in the bass! A great fit for EDM & rap tracks.

Enhance Clarity VectorENHANCE CLARITY: Add audio brightness and pop-sensibilities, let each layer stand alone.

Mastering is an art, not a science and despite the technological achievements of this release, the human ear will always be the most accurate and delicate piece of music equipment ever created. There will always be a need for mastering professionals, we hope this service will bring more recognition and therefore opportunities to the professional mastering engineers who are part of the global BandLab community.
