We take a creative approach to mixing, best summed up as "We mix and master your song as if it were our song".
This means we'll take the time to mix it as if it were our own song, and if we notice any issues or ways we can improve it, we'll let you know.
But basically, professional mixing and mastering include things like correctly applying pitch correction (Autotune), compression, EQ, reverb, delay, and panning to your vocal and instrument tracks.
Mastering includes applying high-quality EQ, limiter, compression, and harmonic exciters to the final mix to ensure that your song will sound like industry standard productions.

Our pricing is based on the number of tracks in the song, the more tracks in the song, the more time it takes to mix them. Each package has its own benefits. For example, the ICON pack has unlimited revisions and additional versions.

That will depend on the package you'll choose. Our single services and Advanced pack includes 1 revision, VIP pack - 3 revisions, and ICON pack - UNLIMITED revisions.
We'll make the required changes and send the new version back to you in 2-5 days after receiving your comments.

Each song consists of many tracks: you have the kicks, snares, hi-hats, bass, vocals, synth, piano, etc. Each one of those is called a track.
When we say "16 track mix," we're referring to mixing 16 separate tracks within the song. To make your songs sound their best, we need all those trackouts (usually referred to as stems) such as the kicks, snares, hi-hats, bass, vocals, and ukulele (can't forget the ukulele) to be their own separate waveform so we can better mix the entire song.
If you need help exporting your tracks, let us know, and we'd be happy to show you.

It'll take up to 3 days to get your song back.

Yes, we work with music sung or rap in all languages.

When you click "purchase now" on the order form, you can select how many songs you want to be mixed and mastered.
