Why Choose Neptune Mastering?See What Makes Us Stand Out.

With today’s digital music market open as it is, many producers/labels don’t see the need for mastering or do “it” themselves. However they forget or maybe underestimate the value a good mastering can bring to a release.  Besides the fact that the mastering engineer will have a fresh, unbiased ear (that you will not have after spending hours, days or weeks on a song), we also have the equipment, the experience and the facility to hear the tiniest details.

Our +15 years of music industry experience enables us to recognise important details in your music and put the focus on making your audio sound better.

Stem Mastering

Individual audio tracks are grouped together to allow for independent control and signal processing of each stem and can be manipulated independently from each other. Stem Mastering should only be used if there are serious problems in the final mix. Preferably you would fix these types of problems during mixdown. If you can not go back and redo your mix Stem Mastering is the way to go.

Mix Down

Audio mixing skills take years of time to hone which can be frustratingly difficult when first starting to produce. Sometimes stereo or stem mastering is not enough to reach the outcome desired. This professional mixing service will transform your song into a tight, punchy, well-balanced, fat mix with correct stereo width that lets all your hard work shine through.
