Description
reproduce step:
- compile the newest opus.
- opus_demo.exe -e audio 16000 1 16000 -inbandfec -loss 30 ./near_16000_1_after_ap.pcm ./out
3.opus_demo.exe -d 16000 1 ./out ./decoded_16000_1.pcm
compare these two file, decoded file will listen worse than before.
I use 1.1.5 opus_demo to test in these steps, everything will be well. Please help me to check.

Research direction
Start by reproducing the two opus_demo.exe commands with near_16000_1_after_ap.pcm and compare the decoded output with the supplied 1.1.5 and newest-version files. Trace the encoding and decoding behavior for 16 kHz mono audio with in-band FEC and 30% loss; done means the newer version no longer produces audibly worse output than the 1.1.5 result.
