Quiet Video Dialogue Checker
Choose a spoken scene from a quiet video and measure whether the source audio is genuinely low, already near its peak limit, or too inconsistent for a simple volume increase.
Your video stays on this device. The selected audio sample is extracted and measured locally.

What to do next
This tool measures audio level; it does not recognize speech or separate voices from music and noise. Use a sample that contains the dialogue you care about.
Test the scene that actually sounds too quiet
A video can contain a loud intro and quiet conversation later. A whole-file average can hide that problem, so this checker lets you choose where a 30-second sample begins. Select a representative section with normal dialogue rather than silence or a music-only scene.
Level and clarity are different problems
A low measured level with available peak headroom can support a cautious gain increase. Strong peaks with quiet words point toward inconsistent levels. Dialogue buried under wind, traffic, or music may remain difficult to understand even after everything becomes louder.
Why this tool does not edit the video
The web checker answers a smaller question: whether the source scene is quiet and how much peak room remains. Editing, comparing, and exporting the complete video stay in the iPhone app, so the diagnostic remains fast, private, and focused.
FAQ
Questions about this tool
Does the checker upload my video?+
No. The selected section is extracted and measured locally in your browser. The video and extracted audio are not sent to this site.
Can it separate speech from music or background noise?+
No. It measures the combined audio level in the selected scene. Choose a representative section with the dialogue you care about and interpret the result alongside what you hear.
Why does it analyze only 30 seconds?+
A focused sample keeps local processing practical on mobile devices and lets you test the exact spoken scene that sounds too quiet.
Will it make the video louder?+
No. It diagnoses the source video without editing or exporting it. If the source is measurably quiet and has peak headroom, the iPhone app is the separate editing workflow.
