Are files uploaded for this tool?

This browser tool processes the selected media locally on this device. The file is not uploaded to ArtPlayer servers for this workflow.

Will the export have a watermark?

No. ArtPlayer browser tools do not add watermarks to exported files.

Why can processing take time?

The work runs in your browser, so speed depends on your device, browser, memory, source size, and the export settings needed for the result.

Which browsers work best?

Recent Chrome, Edge, and other modern Chromium browsers usually work best for heavier browser media processing.

What should I try if a large file fails?

Try a smaller source, close other heavy tabs, reduce resolution or duration first, and keep the tab open until the export finishes.

What does integrated LUFS measure?

It estimates perceived loudness across the whole file using K-weighting and gating, making it more useful for delivery checks than peak level alone.

Is the displayed peak a true-peak value?

No. This first version reports sample peak in dBFS. It does not claim oversampled true-peak measurement.

Does the audio leave my device?

No. Mediabunny decodes the file and the loudness analysis runs locally in this browser.
