    Voice Isolator

    Extract vocals from audio using mid/side channel separation and voice-frequency EQ filtering.

    ℹ️
    For best results, use stereo recordings where vocals are centered and instruments are panned. The Mid/Side mode works well for music; EQ only works for any mono or stereo file.
