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.

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

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

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

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

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

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

Three steps to finish the browser workflow.

1
Choose audio
Measure integrated LUFS, sample peak, and RMS locally in your browser without uploading the audio.
2
Measure loudness
Mediabunny decodes the audio locally while a streaming loudness analyzer measures K-weighted loudness, peak level, and RMS.

Core details about privacy, browser support, output, and practical limits before you start.

Measures gated, K-weighted loudness for practical delivery checks.

Shows sample peak and average signal level beside LUFS.

Reads decoded audio in small chunks instead of uploading it.

Check supported inputs, output formats and usage requirements before you start.

Supported input	Audio files such as MP3, WAV and M4A. Supported codecs depend on the browser and processing runtime.
Output result	Integrated LUFS, sample peak and RMS measurements; no processed audio file.
Processing and privacy	Processing runs on this device. Source media is not uploaded for this workflow.
Browser requirements	A browser with the decoding and encoding capabilities needed by the selected media. Available codecs vary by device.
Usage limits	Processing capacity depends on duration, dimensions, codecs, settings and available device memory. Large inputs can fail; keep the original file.
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.
