Speex dev - Aug 2004 - What is the format of the PCM/WAV data forspeex_encode & speex_decode?

Ok, I'm using 1.1.4, so I should pass signed short(wav data) directly to
speex_encode()?

But the samplecode that comes with 1.1.4 shows me to put short in float
array, and pass the float array to speex_encode()

Speex 1.0.3 uses floats, but the unstable version 1.1.x uses short.

First, I'd like to ak why you want to use 1.1.4. If you don't need the
new features (fixed-point or preprocessor), you should probably stick to
1.0.3, which has received more testing. If you choose to use 1.1.4, you
need to send shorts to speex_encode/speex_decode.

The document hasn't been updated for 1.1.x.

I thought it would be more update/better/faster, any thing wrong?
In the future, would you use short, and forget about float?
If so, I use 1.1.4, I wouldn't need to change my code in the future, right?

You said, it's unstable, yes, I got compiling errors with MsVC6 and MsVC.net
And I modified it a bit to get it compiled. Should I post the errors here?
