How to clean noisy podcast audio
Updated 29 October 2026
Background hum, a fan or a noisy street can make a good conversation tiring to listen to. There are three levels of fixing it, from light to heavy.
- Start with quick cleanIt tidies the recording and levels the voice. It runs on our side and costs no credits. For a decent recording this is often enough.
- Try studio voiceA fuller, closer sound: it removes rumble, evens the voice out and trims silence at the ends. Also free.
- Use AI noise removal for a rough roomIt sends the audio to an AI service that separates the voice from the background. It works on traffic, fans and echo, and uses credits per minute of audio.
- Compare before you decideVandcast shows how far the voice sits above the background before and after, in dB, and you can undo and try another preset.
- Stop it at the source next timeClose windows, turn off the fan, record on a soft surface. Cleaning helps, a quiet room helps more.
Tip: Do not stack every preset. One good pass sounds better than three heavy ones.
