I am importing an audiofile to Mathematica and want to play it back at double speed. The only functions I see are the advanced options of AudioPitchShift (which doesn't alter the duration but increases the pitch) and AudioTimeStretch (which doesn't alter the pitch but does alter the duration). However, I want it both at the same time, half the duration, double the pitch. Which function should I use?

  • $\begingroup$ Can't you compose those two together, with a judicious setting of options, to achieve the result you want ? ie, something like AudioTimeStretch[AudioPitchShift[myaudiofile, dp], 0.5] $\endgroup$ – High Performance Mark May 27 '19 at 15:19
  • $\begingroup$ Yes I can, but I suspect there is a faster & simpler option which I am overlooking $\endgroup$ – DM037 May 27 '19 at 15:24
