Bug description

Decoding MC-format content into binaural output, the high bitrates using MCT+CRend produce distorted output when using 5 ms or 10 ms rendering frames.

Decoding with 20 ms frames the distortions do not appear.

MSAN/ASAN do not reveal anything relevant.

Ways to reproduce

Encoding:

IVAS_cod -mc 5_1 192000 48 ../scripts/testv/stv51MC48c.wav stv51MC48c_192k.bs 

Decoding:

IVAS_dec -fr 5 BINAURAL 48 stv51MC48c_192k.bs stv51MC48c_192k.wav 

The resulting signal has bad distortions.
