Overview

The Audio Dialog Isolation tool uses a high-performance HT-Demucs FT neural network to separate vocals and accompaniment from any audio file. Running entirely in a secure Node environment, it processes your audio locally to extract clean stems and packages them into a single ZIP archive in your preferred format.

When to use

When you need to extract clean vocals or dialogue from a mixed audio track for remixing or voiceover work.
When you want to remove vocals from a song to create a high-quality karaoke backing track or instrumental accompaniment.
When you need to isolate speech from background music or noise in podcasts and video recordings.

How it works

1Upload your audio file in any standard format up to the 100MB file size limit.
2Select your desired output format, such as WAV, FLAC, MP3, M4A, OGG, or Opus.
3The HT-Demucs FT neural network processes the audio to separate the vocal and accompaniment stems.
4Download the generated ZIP file containing the isolated audio tracks.

Use cases

Isolating dialogue from background music for video editing and post-production.
Extracting clean vocal stems for music production, sampling, and song remixing.
Creating instrumental backing tracks from full songs for karaoke or live performances.

Examples

1. Extracting Vocals for a Music Remix

Music Producer

Background

A music producer wants to create a remix of an indie song but only has access to the final mixed stereo track, not the individual multitracks.

Problem

The producer needs to isolate the lead vocal line cleanly without any bleed from the drums or guitars.

How to use

Upload the stereo song file, select 'WAV' as the output format to preserve maximum audio quality, and run the isolation process.

outputFormat: wav

Outcome

A ZIP file containing a clean vocal WAV stem and a separate instrumental WAV stem, ready to be imported into a digital audio workstation (DAW).

2. Creating a Karaoke Backing Track

Vocal Coach

Background

A vocal coach needs an instrumental version of a popular song for a student to practice over, but no official backing track is available online.

Problem

The original song contains loud, centered vocals that distract the student during practice.

How to use

Upload the MP3 of the song, select 'MP3' as the output format for a smaller file size, and start the separation.
