Already have a wind stem? Upload that instead. Brass Section comes out cleaner because competing parts are already gone.
Brass Isolator — built for real audio work
Arrangement Analysis
Isolating the brass section makes it easy to study voicing, harmonization, and articulation in complex big band or orchestral arrangements — without other sections in the way.
Brass-Specific Training
MusiCraft's brass mode is optimized for brass timbres, distinguishing brass from woodwinds and strings far better than a general-purpose stem splitter.
Minus-One Practice Tracks
Extract the 'other' stem (everything except brass) to practice your trumpet or trombone part over the full rhythm section — the classic minus-one rehearsal format.
Use Brass Isolator in three steps
No desktop install. Upload, separate, then solo or mute stems in the browser before you download.
Who it's for
Session musiciansIsolate buried parts so you can hear voicings and lines clearly before you write them down or learn them by ear.
Cover artistsPractice over the real arrangement with a minus-one mix — same tempo, key, and feel as the original track.
ProducersPreview stems in the browser, then pull only what you need into the DAW for edits, mashups, or sample study.Frequently asked questions
