Audio Quality
         
        
            The quality of the audio with speed change can be a serious issue for some videos. Obviously if you are
            watching a tennis video, the audio quality is not of particular importance and in fact you may simply want
            to turn it off. However, if you are watching a video of a musical instrument, the usefulness of the video at
            slower speeds is related to the quality of the audio. If there is so much distortion that you cannot hear
            accurately what is being played, the value of slowing the video (and audio) down is lost.
        
        
            Video Surgeon uses the same high quality algorithm for speed and pitch change technology that is used in our award
            winning Song Surgeon software. If you start with a good quality A/V file you should be able to slow it down
            and have sufficiently good quality to hear what is being played, regardless of what musical instrument you             might play.
