[solved] Sampler audio is sped up?

  Hate to bombard the forum with questions

  That's what it's for!

  The audio sounds fine when I play it through the file pool, but during the actual task it is sped up considerably.

  The playback sampling rate is fixed at 48Khz in OpenSesame 0.24. Your sound file probably has a different rate (33Khz?), which is why it sounds sped up. There are a few simple tricks to get around this:

  • Your own trick. Calculate the conversion factor (e.g., 33/48.1 = 0.6875 -> 68.75%) and adjust the pitch accordingly.

  • Resample your files to 48Khz using a tool such as Audacity: http://audacity.sourceforge.net/

  • Try the latest OpenSesame 0.25 pre-release. This allows you to adjust the sampling rate of the OpenSesame mixer (but it's an unstable release!)

  Hope this helps!

  Thanks for explaining. Calculating the conversion factor will work for me until the latest version is ironed out.

  Hi

  I've also got problems with the sampling rate. I followed Sebastiaan's suggestion and tried editing the general script. The funny thing is that the general script already showed the new sampling rate!

  I solved the problem calculating the sampling difference as you advised mpaulin to do. That worked for me as well.
