01
Validate the source file
We check the supported format, file size, duration, and whether the audio can be decoded. Audio that the user is not authorized to use is not eligible.
MR Maker quality review
How we evaluate vocal-removal results
MR Maker publishes the checks used for uploaded audio and generated instrumentals. This is a reproducible review process with clear limitations, not a promise of perfect separation.
Last reviewed:
02
Compare matching passages
We compare the same passages at a similar listening level for lead-vocal residue, backing-vocal bleed, drum or bass damage, and changes in stereo width.
03
Check technical integrity
We verify that the result plays through, preserves a plausible duration, and contains no unexpected silence, clipping, or broken encoding.
04
Pass or retry
A job is complete only after file generation and basic integrity checks pass. Failed processing does not consume credits; a different quality option or a better source file may be recommended.
Known limitations
- When voices and instruments share frequency or spatial information, vocal residue or instrument damage can remain.
- Live recordings, strong reverb, lossy compression, and choirs are harder to separate.
- MR Maker does not grant copyright or commercial-use rights. Users must verify rights for the source and output.
- This page does not claim a public benchmark score. Results vary with each source recording.
Technical references and accountability
The review categories are informed by music-source-separation research and public audio-processing documentation.
