I am working with a PowerPoint that has audio for each slide. I am trying to get the over all size down after I publish through Flashspring 3.0.

Seems when I try and publish below audio below 64kBit/s the size goes UP NOT down???

This is the test. I have an MP3 at 128 kBit/s Mono at a size of 2.07 megs.The slide it self is 1.07 megs.

1) Audio Export settings: 128kBit/s forced @ 64kBit/s = SWF thats 1.75 megs

2) Audio Export settings: 128kBit/s (keep orginal bit rate) = SWF thats 2.65 megs

3) Audio Export settings: 128kBit/s forced @ 48kBit/s = SWF thats 1.75 megs

Whats the deal with the size getting larger? Even if I use an MP3 and its original bit rate is lowered to 64kBit/s, I cant get the over all size down?

Does Flashspring export in stereo or Mono?

Really need some help. Does anybody have a good solution to this?

Thanks
Erik

What other compression options are specified?

FlashSpring keeps number of channels unchanged.
