Thanks for the excellent information, Kim. I figured stereo would be something like that, but I wasn't sure if it was a block of left samples followed by a block of right samples, or whether channels alternated on each sample. Thanks for the clarification.

The Flite software only comes with an 8 Khz voice right now. Future versions might have 11khz voices. I am going to try to mix in some of the upsampling code that Rob pointed me to and then try to hack in the mono-stereo conversion on my own. After all of that work, I can only pray that it performs fast enough to allow for somewhat real-time text-to-speech. Hey, I've been wanting to dig into a more low-level project on the Empeg, so this isn't totally a bad thing. Should be fun.
