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.

Linear changes gain at a constant rate. Smooth eases the gain near each end for a gentler transition.

Yes. Set either duration independently or use both in the same export.

No. The original stays unchanged and the tool creates a new local audio download.

Three steps to finish the browser workflow.

1
Choose audio
Add precise fade-in and fade-out timing to audio, preview the result, and export it locally.
2
Apply fades
The browser applies a continuous gain envelope to decoded audio samples, then Mediabunny exports a new file.
3
Preview and Download
Check the finished result, then download the exported file.

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

Set independent fade-in and fade-out durations.

Choose a direct linear fade or a gentler smooth curve.

Export MP3, WAV, or M4A without uploading the source.

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	Export options: MP3 / WAV / M4A.
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.
What is the difference between linear and smooth fades?	Linear changes gain at a constant rate. Smooth eases the gain near each end for a gentler transition.
