Hi,

I've been trying to remove the hiss from the audio of an MP4 video that was recorded using a Samsung S9 (AAC encoding , 48kHz) but when I apply it the sound becomes choppy rendering the filter unusable. Does anybody have any ideas why this isn't working or more importantly how to stop it happening - I've spent quite a bit of time on google but can't see any reference to a similar problem? This is after I highlight a quiet section at the beginning for hiss analysis and then apply the Hiss Removal to the whole track. It doesn't happen with the Preset Hiss removal settings. The sound file is after applying the filter and the screenshot is the spectral frequency view after applying the filter showing the introduction of a regular artefact. The original hiss is around 2-3kHz on the left channel.

I've tried up and down sampling the file into WAV format and a different computer with the same result.

Thank you for any advice.
