Improper output observed for test case scaled +10dB input test_param_file_tests[stereo at 48 kbps, 48 kHz in, 48 kHz out, DTX on, MONO out, random FER at 5%]
The floating-point decoder for +10dB input is generating an output whose waveform looks different than original input.
Encoded stream (+10dB): stereo10dB.192 Encoded stream (original): stereoorig.192
In the below picture, first wavform corresponds to floating-point decoder for +10dB input, second for original input case with floating point decoder and 3rd one is fixed point decoder output for +10dB input
The highlighted portion shows the deviation observed with floating-point decoder which is leading to high MLD when compared with fixed point decoder output.
Decoder command: IVAS_dec -fr 20 MONO 48 stereoorig.192 orig.wav IVAS_dec -fr 20 MONO 48 stereo10dB.192 10dB.wav
