Hear it
Hear a raw vocal become a master.
Slow It Down, raw and finished. Switch while it plays.
Slow It Down
Hip-hop, 95 BPM, 30 second clipMeasured on these clips. The mix leaves headroom on purpose, so it sits quieter than the raw file. The master brings the song to release level without clipping.
From your files to a master in four steps.
- 01
Bring your files
Your beat and each vocal as its own file: lead, doubles, adlibs. Up to 12 files, in WAV, AIFF, FLAC, MP3, OGG or M4A.

Check the tags
Rumi listens to your stems and suggests a tag for each: Beat, Lead vocal, Doubles and Adlibs. Check every tag and change any with a tap.
- 03
Pick your sound
Pick a vibe, or keep Rumi's neutral start. Then fine-tune brightness, warmth, reverb, de-ess and breath.

Questions, answered.
Can Rumi mix a vocal and a beat that are in one file?
No. Rumi needs your beat and your vocal as separate files, so it can balance them. A freestyle recorded in one file, with the beat playing in the room, won't work.
Can Rumi master a song that's already mixed?
Not by itself. Rumi mixes and masters from your beat and vocal files. It doesn't take a finished stereo mix on its own.
What files can I upload?
Up to 12 files for one song. Each file can be up to 100 MB and 4 minutes long, in WAV, AIFF, FLAC, MP3, OGG or M4A.
How long does it take?
It takes a few minutes, plus any wait in line when Rumi is busy. No need to wait around. Your master is saved when it's done.
Is the first master really free?
Yes. Every account gets one free master, with up to 5 free changes on that song. No card needed. Creator is coming soon, with 5 masters a week for $19.99 a month.
Does Rumi add autotune?
Autotune is coming soon. It isn't in the beta yet.
