Thanks for your response.
If you are okay with it then it would make sense to push this patch to
master first then because you have to rebase aactab.* to INTFLOATs anyway.

Could you consider moving ltp.c into the aacdec_template.c file? It's
relatively short (compared to the decoder source) and it's only used a
single time in the entire libavcodec by the aac decoder? Perhaps you can
just inline the whole function in the decoder. When compiling aacdec_fixed
it prints a warning saying it expects float * rather than an INTFLOAT *.
