The best place to look for an example implementation of most codecs
these days is the reference code published with the specs. However, I
don't think the EVRC specification or code if freely downloadable. If
you have the specification, I would have thought you would also have the
reference code.
Excuse me for asking, but why do you need help with probably the most
trivial problem in implementing a codec? Almost any IIR filter designer
should produce a usable Butterworth implementation for you, although
some produce a single stage and leave you to break it into bi-quads.
Regards,
Steve

Is there somewhere a free code of a EVRC coodec?
Or at least a sample of the first 6th order Butterworth filter?
