Pitch Shift Vs. Speed Shift

Colin Hart has posted an interesting article over on his website. The article is in response to an idea that David Sonnenschein and I discussed when talking about Colin’s winning entry in January’s Sound Design Challenge. Specifically, we were wondering if there was a perceivable difference between a 192k recorded file when it was pitch shifted via plug-in processing, or when it had been forced to play back at a slower sample rate. It’s an interesting idea to consider in the design process.

One of the things I like to do in my sound design is to record at 192k. It opens up a world of options to you – you can do lots of cool things like major pitch shifting (since 192k will capture up to 96kHz, and most pro recorders are capable of 40 – 50k) and major time stretches (since you have 4x the data as 48k) without incurring any major sonic degradation. I love recording at 192kHz and then forcing it to play back at 44.1kHz. You get a lot of really cool sounds – some very deep, yet sonically full sounds.

Head over to Colin’s site to find out the results of his experiment.

  1. This is very cool, been using it so much now I feel like the guys from Time Warp lol
