High frequency differences above 6 kHz, 7.1+4 MC with FER at 32kbps
# Basic info <!--- Add commit SHA used to reproduce --> - Encoder (float): d9fdb374 - Decoder (float): d9fdb374 - Decoder (basop): 9636c06d # Bug description High frequencies are not correctly reproduced above ~6 kHz with 7.1+4 input and output with FER, despite the low MLD value (MLD at 32kbps = 0.47399607). Audible differences especially at the channels 5-12. Affected bitrates are at least 16.4, 24.4 and 32 kbps. Differences of the spectrograms are clearly visible: ![Screenshot_2024-10-23_at_13.43.33](/uploads/96d7404787f039d1c4d0fc25c4e1c379/Screenshot_2024-10-23_at_13.43.33.png) # Ways to reproduce ``` ./IVAS_cod -q -mc 7_1_4 -max_band fb 32000 48 in.wav bit ./eid-xor -fer -vbr -bs g192 -ep g192 bit /scripts/dly_error_profiles/ep_10pct.g192 bit_eid ./IVAS_dec -q 7_1_4 48 bit_eid out.wav ``` <!--- Below are labels that will be added but are not shown in description.
