There are several libraries for Linux which increase audio speed without affecting pitch, the best-known being libsoundtouch. To my knowledge, libsoundtouch has no been formally incorporated into any media player. However, there is a relatively new project called ScaleTempo (<a href="http://scaletempo.sh.net" target="_blank">http://scaletempo.sh.net</a>) which provides this capability for several media players, including VLC (into which the patch has formally been accepted). Please test a ScaleTempo-enabled version of whatever media player is currently used to view Technion video (vlc, if I'm not mistaken).<div>
