  1. Does sample rate have any effect on processor usage? I have a podcast that’s 64 kbps but 48000Hz, seems like a waste. I downscale them to 32000Hz to supposedly use less processor. Am I wasting my time doing that?

 

  1. Is there any difference on processor usage between MPEG-1, MPEG-2, and MPEG-2.5 (all Layer III) mp3 files? I would think that MPEG-1 would be the simplest.

The sample rate question depends a lot on how the player handles other sampling rates. I can’t speak for the Sandisk firmware. There is no meaningful difference between MPEG1/2/2.5. They’re all the same format.
