Speex dev - Jan 2007 - Integer Version with low bit rate for Linux Kernel?

Hello,

 

I am looking for a speech codec with low bitrate, 2000 (desired) to 2400
(max) bps.

 

It should run in c code within the LINUX Kernel, fully integer based.

 

Is this possible with speex?

 

Thanks

Speex has a 2.15 kbps mode. It doesn't sound very good though.

It's written in C, but it's not (yet) entirely in fixed-point (integer).
Most of it is converted (the higher bit-rates are entirely fixed-point),
but there are a few float ops left IIRC.

Yes, if you convert the rest of the code to integer.

You want to run Speex *inside* the Linux kernel?  Why?
This almost certainly is a mistake.
