When I upload an audio file (and an image together) on youtube, it does not recognize the words. The audio quality is that of a portable recorder; for me the words are enought clear. Is there a way to improve audio quality? I've already tried to do this with audacity, but the quality is worsened. Thank you in advance.
P.S. I know that the transcriptions of youtube are inaccurate, but this is not a problem, the most important thing is to recognize the audio file.
