voice isolation

Voice isolation is notoriously difficult. It’s like trying to extract a banana from a banana milk shake.

This sample has been produce by using the “Vocal Removal” effect in Audacity 1.3.13, then using the result as a noise profile in the Noise Removal effect, and applied to the original audio track. The Equalization effect has then been applied to remove low bass and high treble. Finally the track has been “Envelope” shaped to remove the unwanted parts. With more time and effort tweaking the effects you may achieve slightly better results (this was done quite quickly), but I’ll be surprised if you get much better.

Hi steve, total beginner here. Could something like my attached clip be cleaned up for voice isolation given that the background noise is inconsistent? Would appreciate your input, thx!

Try using the “Vocal Reduction and Isolation” effect with the default settings (as shown in the picture in the manual: http://manual.audacityteam.org/o/man/vocal_reduction_and_isolation.html) except for the “Action” control which should be set to “Isolate Vocals”. It can not completely remove the music because some of the sounds are in the same frequency range and the same pan position (panned to the centre) as the voice. “Some” of the music is reduced, and that’s as good as it gets.
