Unexpected tone at around 2khz in fixed point output at 13.2 kbps SBA
Basic info
issue description
Unexpected tone at around 2khz in fixed point output at 13.2 kbps SBA. The presence of tone is more obvious in the right channel of the binaural output during silence/inactive frames. The tone can be seen in FOA output itself (although the level is very low around -90 dbfs)
Ways to reproduce
bitstream: Box_EXTERNAL_IVAS_BASOP_VERIFICATION\issues\issue-952\bit
input file: Box_EXTERNAL_IVAS_BASOP_VERIFICATION\experiments\selection\BS1534-4b\proc_input_d\dm4ba1s09.wav (issue can be reproduced with many P800 FOA inputs as well)
encoder cmd line: -sba 3 13200 48 in.wav bit decoder cmd line: FOA 48 bit out.wav renderer cmd line: -i out.wav -if FOA -o outbin.wav -of BINAURAL -fs 48
(Clear steps or refer to a failing automated test, e.g. with a pipeline link)
