Example: David Gooding lecture.
A clearer voice is the point.
For an interview, spoken note, or recorded talk, you want to hear what was said. Diffio focuses on restoring recorded speech rather than making you build an audio-editing workflow around it.
Know what you are testing.
Here, voice isolation means reducing background noise around recorded speech. It does not mean extracting a singer from a song or separating one person from several overlapping speakers.
