> TL;DR: Type "Remove the background hum from my voice" and Vidiyo measures your recording's noise floor and speech level, then applies noise reduction tuned to that measurement, plus EQ for hum and rumble. It measures again and reports the noise and speech levels before and after, so you know the voice wasn't over-cleaned.

## What Vidiyo does

1. Measures each voice clip's noise floor, speech level and signal-to-noise ratio.
2. Applies noise reduction set to the measured noise floor on every clip from that recording.
3. Adds a high-pass filter for rumble, or narrow cuts at the mains hum frequency.
4. Adds EQ, a de-esser or compression when the voice also sounds muddy, harsh or uneven.
5. Measures again and reports the noise floor and speech level before and after.

A fan, a fridge or a hum from a cable can sit under a whole recording. Viewers forgive soft video faster than noisy audio. This prompt cleans your voice from measurements, not by guessing.

## What does Vidiyo do when you say this?

Vidiyo measures each voice clip's noise floor and speech level, then applies noise reduction tuned to that exact floor on every clip from the same recording. For hum or rumble it adds a high-pass filter or narrow cuts at the mains frequency. Then it measures again and reports the noise floor and speech level before and after.

Matching the measured floor matters: noise reduction set even a little off removes much less noise. The assistant aims for clean speech without pulling the voice down, and if speech level drops, it eases the reduction off. If your voice also sounds muddy, harsh or uneven, it can add EQ, a de-esser and compression in a fixed order, starting from tested voice presets.

## How do you phrase it?

Describe what you hear:

- "Remove the background hum from my voice"
- "There's a fan noise, clean it up"
- "My voice sounds boomy and muddy"
- "The S sounds are harsh"
- "Make my voice sound like a podcast"

The last one asks for a whole chain: noise reduction, EQ, de-essing and compression. A specific complaint gets a specific fix.

## How would you do this by hand?

By hand, you'd open a noise reduction effect, capture a noise profile from a quiet stretch, set the amount by ear, add a high-pass filter, maybe an EQ and a compressor, and solo the voice to compare. Then you'd apply the same settings to every clip from that recording. Getting it right by ear takes practice and good headphones. Here the starting point comes from a measurement.

## What should you check afterwards?

Listen on headphones to a quiet stretch and to your loudest sentence. If the voice sounds hollow or watery, ask for "less noise reduction". If some hiss remains, ask for a little more. Recording in a quieter room helps more than any processing, so a clip that's still noisy may be worth re-recording.

## Honest limits

- Noise that changes a lot, or noise as loud as your voice, can't be fully removed.

## Frequently asked questions

### Does the noise reduction happen on my Mac?

Yes. Audio processing is local, and the assistant only sees the measurements.

### Can it remove any noise?

It handles steady noise well: hum, hiss, fans, air conditioning and room tone. Changing noise like traffic is harder, and loud noise over your words can't be fully separated from the voice.

### Will my voice sound processed?

The assistant starts gentle and checks that speech level barely moved. If the voice drops, it backs the reduction off. You can ask for less any time.
