Sugestion: volume normalization, compression (as in audio effect, not as in zip). A lot of people have shitty mics or change their distance.

Opening the picture in Windows Photo Viewer (the old on introduced in Windows 7) throws this error: "Windows Photo Viewer can't display this picture because there might not be enough memory available on your computer."

Other Windows included apps, like Paint, Paint3D and Photos open it just fine.

Paint is like the Notepad of Artwork apps. It can handle anything.

If notepad doesn't open it, nothing will.
