Help for newbie - isolating voice

Hi, using windows 10 and version 2.1.3 of audacity.

I am a complete beginner with stuff like this and not computer savvy at all! I have a sound clip of a person talking with the television on in the background. How can I isolate the voice of the person talking and get rid of the television noise?


If the TV is a lot quieter than the voice, you might be able to help with Noise Gate.

Noise Gate is designed to let loud sounds go through and not quiet ones. If they’re both about the same volume, I think that’s the end of the world. Number 4.

The Four Horsemen of Audio Recording (reliable, time-tested ways to kill your show)
– 1. Echoes and room reverberation (Don’t record the show in your mum’s kitchen.)
– 2. Overload and Clipping (Sound that’s recorded too loud is permanently trashed.)
– 3. Compression Damage (Never do production in MP3.)
– 4. Background Sound (Don’t leave the TV on in the next room.)

Are we trying to rescue a podcast performance? AudioBook? If the TV is higher volume than the voice, nobody will be able to bring it back.


Yes the voice is quieter than the TV :frowning:
So I can’t do anything then?

No… What’s this for? If you can make-out what’s being said can you type-up a transcript or if it’s part of a video, turn-down the volume and add subtitles, etc.

The human brain of often the best filter… If you can’t understand what’s being said there’s probably nothing you can do. …And if this is for any “legal purposes”, you have to be very careful about altering the evidence.

Pros still record in soundproof studios. Radio station studios and TV newsrooms are soundproof. On-location movie dialog is re-recorded in the studio, etc.
