# Basic info <!--- Add commit SHA used to reproduce--> - Float reference: - Encoder (float): - Decoder (float): - Fixed point: - Encoder (fixed): - Decoder (fixed): # Bug description For some items selected for P800-7, there are audible artifacts in the BWE region. this occurs e.g. for cat2, items 1 and 6 and cat4, items 2 and 3. The mentioned items sound worse than the next-lower bitrate. The issue appears for 96 and 64 kbps in full-chain fixed-point output, but only at 96kbps for mixed output. So, it does NOT occur for 64kbps float enc -\> fixed dec and it does occur for 96kbps fixed enc -\> float dec. This hints at an encoder problem. At least from visual inspection of the spectrograms, it looks different from e.g. #2017 and #2016. Perceptual impact is quite audible, for me worse than the next-lower bitrate which does not have it, so 64 or 48 kbps, depending on if it is mixed or fx full-chain. It does not occur in all items, but in many of the speech (!) items. The music items do not have it, but seem to also suffer from something like #2014 or #2010. This particular example below happens for -36dB only Float full chain 96kbps, item is cp07a4s03:  Fixed-point full chain:  # Ways to reproduce Box folder: ...\\Box_EXTERNAL_IVAS_BASOP_VERIFICATION\\issues\\issue-2021 <!--Commandline or script--> ```bash IVAS_cod_fx -mc 7_1_4 96000 48 20ms_aligned_files_concatenated.wav bit IVAS_dec_fx BINAURAL 48 bit out.wav ``` <!--- Below are labels that will be added but are not shown in description.
