I was able to create a Slidecast but the audio plays at a different pitch or speed on SlideShare. Why?

We use a Flash player for playing audio which supports the following sample rates for mp3 — 44.1 khz, 22.05 khz and 11.025 khz. Some mp3 encoders can also export to 32khz, 16khz and 8khz. Flash does not support these sample rates and will play them at a higher or lower pitch. Make sure your mp3 encoder always outputs at one of the above three sample rates.
