Z channel content potentially missing for FOA
During testing of the processing scripts, unexpected output was encountered when coding a test signal with the IVAS codec.
The input vector SBA_concatenated (please note 32kHz sampling rate)
After coding with FOA@160kbps passthrough, the output looks like this (commit 02c53074):
A similar behaviour was observed with the following noise burst vector too: pink_noise_4ch_48kHz.
Using a much longer diffuse noise vector does not result in the same behaviour:pink_noise_diffuse_N422_HOA3_norm.
I think we should verify whether this behaviour is expected or not, possibly the SBA focused devs might be the best to check?
