Sorry for this simple and maybe stupid question, I'm working in the
implementation of opus for ARMv7e microcontroller using a library CMSIS/DSP
used to calculate the CFFT and MDCT based on the DCT-IV. my question is:
In the implementation of Celt you have used a fixed length CFFT equal to
1920, I want to know if there is some issues which can appear if a change
that configuration for a cfft of size 2048, some of you could give me some
support about that?, I ask because the library which I'm using doesn't
support 1920 size.
please let me know, I you need I could be more specific.
thanks you so much.
