+        lsp[i] = cosf(lsf[i]);

So, in light of all recent discussion on types for whatnot, let's settle this.

What type should LSFs, LSPs and LPCs be? I mean, all decoders do this.
We can easily share it as long as we agree on this silly little thing.

Rest of the patch OK. :-). Now I finally understand how to use AMRFixed.
