You have a video of a family party. You can see your mom talking in the background, but the music is loud and everyone is laughing. Is her voice lost?
Not necessarily. Modern audio technology allows us to "unbake the cake"—to separate the ingredients of a sound file and isolate the voice you want.
The Magic of Stem Separation
"Stems" are the individual tracks of a song or recording (vocals, drums, bass). New AI tools can perform "stem separation" on any audio file, separating speech from noise.
Tools to Try
- Lalal.ai: An online tool that is incredible at separating vocals from instrumental backings.
- Adobe Podcast Enhance: A free tool from Adobe that uses AI to clarify speech and remove background noise. It makes a phone recording sound like it was done in a studio.
- Audacity (Vocal Reduction):
- Import your track.
- Go to
Effect > Vocal Reduction and Isolation. - Select "Isolate Vocals."
Using EQ to "Carve Out" the Voice
If AI tools aren't working, you can try manual Equalization (EQ). Human speech typically lives in the frequency range of 300Hz to 3400Hz.
Want to recreate a loved one’s voice?
EchoAgain helps you preserve and reconnect with the voices that matter most.
Try EchoAgain- Open your file in an editor like Audacity.
- Open the Equalizer.
- High Pass Filter: Cut everything below 100Hz (this removes rumble and bass).
- Low Pass Filter: Cut everything above 4000Hz (this removes hiss and high-pitched noise).
- Boost the Mids: Slightly boost the frequencies around 1000Hz-2000Hz to make the voice more intelligible.
Slowing It Down
Sometimes, speech is buried because it's too fast or mumbled.
- Slow down the playback speed by 10-20% without changing the pitch. This can make it easier for your brain (and AI models) to decipher the words.
When to Call a Pro
If the audio is extremely important but very damaged, consider hiring a professional audio engineer. They have forensic tools (like iZotope RX) that can perform miracles on damaged audio.
Why Bother?
Recovering even a few sentences of clear audio can be enough to train a voice model on EchoAgain. You don't need hours of studio-quality sound; you just need the essence of the voice.
