- Select a local audio or video file to upload or drag and drop it into the shaded area to directly start the upload. An example file can also be selected from the dropdown on the right.
- Press the Start Noise Reduction button to upload and process any selected local file or to produce the processed output for a selected example file. A progress bar shows the progress of the upload.
After the upload completes, the currently selected audio noise reduction settings will be used, if "Fix settings for uploaded file" is checked. Otherwise, the default settings corresponding to the button DSP – I will be used.
- Of the two audio players that appear at section Output, the upper one plays the original input audio while the lower one plays the latest noise reduction result. The latter can be downloaded by pressing the Download button.
- If noise reduction quality of the output needs improvement: adjust denoising parameters using the controls in section Algorithms and do one of the following:
- Keep the radio button next to the original input file player checked and press Process. This runs a different noise reduction operation on the original input.
- Check the radio button next to the output file player and press Process. This applies a subsequent processing phase on the output of the previous phase. With this option, each processing phase gives a different output even if settings are otherwise unchanged.
- To return to previous output, press Previous version. The settings will also change to reflect the previous configuration. Pressing Previous version another time switches back to the newer version.
- The buttons in the beginning of section Algorithms can be used to select preset configurations. These include methods based on digital signal processing (DSP) and artificial intelligence (AI).
- Longer recordings may take a while to process. It may take up to two minutes for the result to first appear after the uploading has finished. The audio player then updates automatically as more of the processed output becomes ready. If it stops updating and does not show the full length of the audio, you can try to reload the page. If that does not help, the full length output may still become available a few minutes later, so you can try to reload the page again.
