Professional audio mastering from Basel
Finalize sound
Audio mastering brings a production to a uniform technical level and prepares it for reliable release on all platforms.

For artists, producers and media companies
Technical preparation of audio content for stable playout via media
Audio mastering is the final processing step of an audio production in which the sound, loudness and technical parameters are optimized for publication. It is used by artists, producers, companies and media houses to reliably prepare recordings for streaming, broadcast or physical formats.
Good audio mastering has a balanced sound, consistent levels and processing that makes the material stable and comprehensible. Frequency balance, dynamics and loudness must be adjusted so that the mix works in different playback situations.
OSLO STUDIOS carries out audio mastering with a structured process for analysis, editing and technical control. All steps are carried out in our own studio and are tailored to the requirements of the target medium.
Typical components are sound correction, dynamics processing, stereo optimization, loudness adjustment, format conversion and playout in the required master formats.

What is audio mastering?
Audio mastering is the final processing of a mix. Frequencies, dynamics and loudness are adjusted, noise is corrected and transitions are smoothed. The result is a technically clean and stable file that sounds consistent on all devices and platforms. Mastering also prepares the material for the desired formats, including standards, exports and release packages.
How is an audio mastering created in the studio?
The mix is analyzed and technically adjusted. The material is then optimized and formatted according to specifications.
Which formats can be mastered?
Music, voice, podcasts, advertising, movie soundtracks and content for digital platforms.
Which loudness standards are taken into account?
Standards for streaming, radio, TV and social media. Mastering is prepared accordingly.
