How Do I Know If My Mix Is Ready for Mastering?

A mix is ready for mastering when its musical decisions feel settled and the export accurately represents the approved version. Mastering can refine presentation and prepare deliverables. It works best when the mix already communicates the performance you want.
Confirm the important balances
Listen to the vocal, bass, drums and transitions at a few sensible playback levels. Check familiar speakers and headphones, then return to your main reference. Make sure a comparison track is at a similar perceived level so loudness alone does not drive the decision.
Resolve issues at the source
Listen for clicks, accidental edits, distracting noise, unwanted distortion and missing words. If the chorus balance or an individual instrument still needs a substantial change, address it in the mix session. Describe any intentional distortion or unusual dynamics in your notes.
Check processing and headroom
Avoid accidental clipping and ask the mastering engineer what file preparation they prefer. There is no universal requirement to place every mix peak at exactly −6 dBFS. If bus processing is part of the sound, discuss it rather than automatically removing it. A comparison export without a loudness limiter can be useful when agreed in advance.
Listen to the actual export
Open the rendered file and check the beginning, ending, fades and loudest sections. Confirm channel format, sample rate and bit depth against the requested delivery. Use the project’s appropriate source resolution; upsampling by itself does not create missing detail.
Make the handoff clear
Send the approved mix, a small set of useful references and concise notes about the intended sound. Identify alternate versions, track sequence and destinations. Agree on deliverables, review procedure and timing before the work starts.
If you are unsure about one remaining issue, raise it directly. A clear conversation is more useful than trying to hide it under another processing chain.
