AI Voice Isolation

Repairing badly recorded audio used to require decades of audio engineering experience and highly complex noise-print extraction tools. Oraphim features an integrated, neural-engine-powered Voice Isolation tool that can salvage unusable dialogue with a single click.

When to Use Voice Isolation

Use this tool when your dialogue recording is plagued by:

• Loud air conditioning hums.
• Traffic noise or sirens in the background.
• Wind noise striking the microphone.
• Unwanted background chatter (like a busy restaurant).

Applying Voice Isolation

Voice Isolation is a native tool built into the Inspector.

1. Select the noisy audio clip on the timeline.
2. Open the Inspector panel.
3. Navigate to the Audio tab.
4. Locate the Voice Isolation switch and toggle it On.
5. The AI will instantly analyze the clip, identify the human vocal frequencies, and mathematically delete all other frequencies.

Adjusting the Amount

Below the toggle switch is an Amount slider (0 to 100).

• If you set it to 100, the background noise is entirely eradicated, leaving only the voice in a completely dead, silent vacuum.
• Best Practice: Total silence often sounds unnatural. It is usually best to set the amount to roughly 70 or 80. This suppresses the distracting noise enough to make the dialogue clear, but leaves a tiny bit of "room tone" so the scene feels realistic.

Dialogue Leveler

Directly below the Voice Isolation tool is the Dialogue Leveler.

If an actor is moving their head away from the microphone while speaking, their volume will wildly fluctuate. Instead of manually keyframing the volume or tweaking complex compressor settings, enable the Dialogue Leveler.

The AI will analyze the speech and automatically boost the quiet syllables and lower the loud syllables, ensuring the voice stays at a perfectly consistent volume.
