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.
