Overview

The Audio Mix tool combines multiple audio tracks into a single file, allowing you to adjust the volume of each track for a balanced mix. It supports various output formats and settings for professional or personal audio projects.

When to Use

  • •To normalize volume levels across different audio segments before finalizing a mix.
  • •For converting mixed audio to formats like MP3, AAC, or WAV for compatibility.

How It Works

  • •Upload two to ten audio files in supported formats.
  • •Specify volume levels for each track using comma-separated values (e.g., 1.0,0.5,0.8).
  • •Select output format, sample rate, and audio channels as needed.
  • •Process the mix and download the combined audio file.

Use Cases

Outcome
A balanced mix where voices are prominent and music is subtle, ready for publishing.

Outcome
A high-quality audio mix that enhances the film's narrative and is ready for synchronization.
