Background

Problem

The podcast platform requires stereo audio, and the original mix has distracting background sounds.

Upload the 5.1 audio file, set the surround level to 0.3 to reduce noise, increase the center level to 0.9 for clear dialogue, and output as MP3.

Outcome

A polished stereo podcast episode with focused dialogue and minimal background interference.

2. Home Theater to Headphones

Background

Problem

How to use

Upload the movie's audio track, adjust the LFE level to 0.4 for balanced bass, keep surround level at 0.5 for subtle ambience, and choose AAC format for compatibility.

Outcome

An immersive stereo mix optimized for headphone listening, with clear dialogue and controlled bass.
