CELT CFFT size configuration
Dear all,
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 b...

CELT CFFT size configuration
Dear all.
According with my question.
CELT CFFT size configuration
I'm not completely sure about how the kiss_fft works for sizes which are
not power of two, as occur in the case of celt which calculate the mdct
using a fft sizes of 480, 240, 120, and 60, I guess that internally the
input data is padded with zeros in order to compute effici...
