Begin with a mix you are ready to finish
Mastering follows the decisions made during recording and mixing. Before handing over a song, listen for issues that still need attention inside the arrangement. If a vocal needs a different performance or an instrument needs a substantial balance change, raise it before treating the mix as final.
Keep track of which version everyone has approved. Clearly naming the final mix reduces confusion when alternate exports, rough mixes and revision files are in the same folder. If you are uncertain whether your song is ready, describe the concern when you contact the studio.
Explain where the music is going
A single, an EP and an album present different planning questions. Tell the studio how many songs are involved and how you expect to release them. If a distributor has specific delivery requirements, share those requirements rather than assuming a particular format or loudness target applies to every release.
For a group of songs, explain the intended sequence and any deliberate differences in mood or dynamics. Mastering is not a reason to erase musical contrast. The useful conversation is about how the tracks should relate to one another while retaining their individual character.
Prepare files after agreeing the requirements
Ask which file format and export settings the studio wants before sending your mixes. Keep the original mix exports safely backed up. If you have used processing purely to make a rough mix louder, explain that choice and ask which version is most useful for the next stage.
Provide concise notes about concerns you can actually hear. Mention the listening context and the point in the song, rather than relying only on words such as “bigger” or “better.” A reference can support the discussion, but it cannot guarantee that recordings with different performances and arrangements will sound identical.
Get a project-specific mastering quote
Mastering is the final production step, with attention to loudness and clarity for distribution. Pricing and turnaround are set case by case. There is no published flat rate, guaranteed delivery window or advertised list of included alternate versions on this site.
Share your song count, intended release date and current mix status. Ask what files you will receive and whether any additional versions need to be quoted separately. If mixing work is still required, discuss it as part of the project rather than expecting mastering to resolve every underlying issue.
