OSBA 160 kbps: Clicks in Concealment

Basic info

• Encoder (float): d9fdb374
• Decoder: 4c7c46f3

Bug description

For the decoded output, there are at a few instances clearly audible clicks in channel 5 (i.e. the first SBA component = the omni signal).

BASOP:

It's audible at e.g. 0.48s and 1.5s. The issue is not there in the float decoder.
