Welcome to SDB Mastering: we're a full-service professional studio in Europe providing high quality audio mastering services.


SDB Mastering is a full-service mastering studio, providing attended mastering sessions and online mastering services. SDB Mastering is the mastering division of Estúdios Sá da Bandeira, one of Portugal's largest independent recording facilities. In total, we have 2 separate recording studios spread across two storeys - plus our mastering room - all built upon a late XIX century building. We have free wifi, kitchen and lounge - plus all the coffee you can handle - so if you're attending we'll make sure you'll be comfortable during your session.

Our mastering room was built from ground up to serve as a mastering studio. It's fully treated and decoupled - built in a room within a room type of configuration - all to ensure a quiet and accurate monitoring environment. Along with a reference monitoring system by ATC and acoustically neutral furniture by Sterling Modular, our room provides a revealing listening experience, key to what a mastering studio should all be about.

Regarding our tools, SDB Mastering is outfitted with a mix of custom analogue gear built by our staff, high-end equipment from known manufacturers and various digital tools from brands such as Mytek, Dangerous Music, elysia, Sonoris, DMG Audio, Weiss, TDR and iZotope. We can work with both analogue and digital sources, including 1/4" tape, DSD sources up to 11.2MHz, DXD audio, PCM audio files up to 768kHz/64bit or even other older formats such as ADAT and DAT tapes.

All engineering work at our mastering room is done by Miguel Marques, who was the owner and mastering engineer at Bender Mastering Studio before partnering with Estúdios Sá da Bandeira and joining SDB Mastering. Besides his work as a mastering engineer, Miguel is also the author of Sistemas e Técnicas de Produção Áudio, a pro audio book written in Portuguese for recording and mixing engineers.

What's Mastering?

Mastering is the final step before the distribution or manufacturing of a music record and is, therefore, one of the most important stages of audio production. It is the final chance to get everything to sound as great as it can sound, in a wide range of different playback systems and formats.

Mastering is the process of converting mixes to records and prepare them to be distributed or manufactured by producing high-quality masters, in CD form, DDP images, vinyl lacquers or digital files. It's in mastering that all mixes are fine-tuned so they can translate well in every type of speaker, where all mixes are balanced and levelled so they can sound related and part of the same record and where all fades and edits are made to produce the final product.

In this digital age where online music stores are a big part of music distribution making sure your music translates well and that it is optimised for every type of format available is also a big part of what mastering is about. We are prepared to master for almost every medium available, be it an audio CD, vinyl or the new "Mastered for iTunes" format.


Our engineer has been mastering music professionally for years, working with both indie and major labels, new bands or known acts, across all music genres. This list is a small sample of the artists, projects and labels that had music mastered by Miguel since 2010.
