Audible discontinuities in DFT stereo for bitrates <= 32 bkps
There is some discontinuities on the right channel only. The following figure shows the right channel of the input file, the float synthesis, the fixed point synthesis and the temporal different between float and fixed point.
The next figure shows the effect on the signal
the bitstream used is attached here
IVAS_dec STEREO 48 tr.bit syn
The decoder runs always in DTF stereo, and the problem is present for bitrates <= 32 kbps
