Our Services

Tailored solutions for your marketing needs.

Stereo Mastering

One of the final steps in the post-production audio process before distribution is stereo mastering. The sole purpose of mastering is to optimize playback across all systems and media formats, and encode the files with the proper information. Common tools that stereo mastering utilizes include equalization, compression, stereo imaging and limiting.

Stem Mastering

Unlike stereo mastering, the process of stem mastering involves processing the final mix as five to ten stems. This gives the mastering engineer more control of each individual grouping or stem. For example, most people typically send: drums, bass, instruments, vocals and effects. Some more stems can be broken out for more control, like kick drums, individual bass sounds, toms and fills.

Vinyl Mastering

Vinyl mastering tailors a master for vinyl records, preventing distortion and needle skipping. Distinct Mastering offers this service upon request. It's crucial for music intended for vinyl to undergo proper mastering, ensuring optimal sound quality. Distinct Mastering is well-versed in the necessary techniques for superior results.

Apple digital masters

Apple Digital Masters is a certification program for mastering studios and engineers that ensures high quality audio is submitted to Apple Music platform. Distinct Mastering is an Apple Digital Masters certified studio and can provide your music to Apple’s exacting standards. Your song must be mastered and submitted by an Apple Digital Masters Certified Studio in order to be approved.

Audio Mixing

Audio mixing services come into play after the recording process. This process involves combining multiple sounds together to make all parts sound cohesive and tonally balanced. The ultimate goal of audio mixing is to create the best possible version of your multi-track recording. During this phase, we will adjust the frequency content of your files, add effects, and modify the spatial position. This will tailor each sound so all instruments have a space in the final balanced mix.
