[regression-merge] SBA decoder in float-pc and main-pc applies different bandwidth extension than ivas-float-update
Basic info
Bug description
Discovered in !1935 (merged) in the encoder regression test.
The decoder build of float-pc and kiene/float-pc-clone-for-merge applies different bandwidth extension than ivas-float-update does. Difference can be seen in the high-frequency parts of the higher order channels (channel 5+) in the spectrograms below.
ivas-float-update:
float-pc:
