How do I assess the result?
Choose a section containing both voice and background noise. Compare Original and Edited at the same device volume. Check that consonants and word endings remain clear. If the voice sounds muffled or unnatural, disable noise reduction.
Can I remove music or another voice?
This tool does not separate vocals from instruments. It does not guarantee removal of music, wind, clicks or another speaker. Strong noise covering the desired sound may remain; processing cannot recover inaudible words.
