## Overview

Isolates the center/dialog channel (FC) from a surround audio file or the first audio track of a video, then outputs it as mono. Useful for dialogue-only stems, clarity checks, or remix workflows where you need the center content separated from the rest of the mix.

## Inputs

- **Audio File** (file): Select a surround audio file (e.g., 5.1)
- **Output Format** (select)

## When to use

- When you need to isolate dialogue or voiceovers from a 5.1 or 7.1 surround sound audio track.
- When preparing audio stems for remixing, localization, or dubbing projects.
- When analyzing the center channel mix for phase issues or level adjustments in post-production.

## How it works

- Upload a surround sound audio file or a video file containing a multi-channel audio track.
- Select your preferred output format, such as WAV, MP3, FLAC, or AAC.
- The tool isolates the front center (FC) channel and converts it into a single-channel mono file.
- Download the extracted mono audio file directly to your device.

## Use cases

- Isolating clean dialogue from a movie scene's 5.1 surround track for voiceover analysis.
- Extracting center-channel vocals from a multi-channel music mix for remixing.
- Creating dialogue-only stems for localization and foreign-language dubbing.
