How to compare a master fairly with the unmastered mix
A louder version can sound more impressive before you have judged what actually changed. Fair comparison starts by removing that distraction. For a focused expert context, see Vlado Meller’s mastering masterclass.
The decision behind the sound
Match playback level and switch quickly. Otherwise the louder version often sounds better for reasons unrelated to quality.
Switch quickly between the mix and master at matched levels. Check the loudest and quietest passages rather than one impressive chorus. Note both improvements and losses, including transient impact and emotional movement.
A mastering decision affects the entire mix. That is why a small tonal or dynamic move can help one passage and hurt another; always compare across the full song.
A useful listening question in the context of Vlado Meller’s mastering programme: “What remains better when the mastered and unmastered versions are compared at a similar perceived level?”
Try this on your own project
Compare two versions at matched level, then listen to the verse and chorus rather than a single impressive moment. Take a break and repeat the comparison.
Name the audible issue before changing a processor.
Change one parameter at a time.
Check the result on another playback system.
A louder version can win a fast comparison without actually translating better. Match playback levels and listen again after a short break.
What matters
The right master keeps the musical identity intact while helping the song translate.
The September 2026 sessions with Vlado Meller have finished. The linked programme shows the focus of that mastering masterclass; it is not an announcement of a new date. Use it to explore the expert background to the listening decisions discussed here.
