Energy leakage in IGF tiles for MDCT-stereo @64kbps SWB
# Basic info <!--- Add commit SHA used to reproduce --> - Float reference: - Decoder (float):de0a9fca - Fixed point: - Encoder (fixed):78cb4903 # Bug description There is an energy leaking to subsequent frames in IGF bands from 10-12kHz for item am1aa1s09 that cause the onsets to have different timbre. This can be seen for many onsets. An examples shown here for timestamps 0.520 sec and 1.600 sec ![Screenshot_2025-01-22_at_16.50.16](/uploads/8019d63cf1d25c1c0a4e480197655797/Screenshot_2025-01-22_at_16.50.16.png) float version: ![Screenshot_2025-01-22_at_16.50.47](/uploads/3601de643991d19b2a0794f9e6737f61/Screenshot_2025-01-22_at_16.50.47.png) appart from that there are serious noise filling differences between the two versions, this is something observed throughout most of the files reported. # Ways to reproduce Box folder: ...\Box_EXTERNAL_IVAS_BASOP_VERIFICATION\issues\issue-1214 <!-- Commandline or script --> ```bash ./IVAS_cod -stereo -max_band SWB 64000 32 am1aa1s09_32.wav out.192 ./IVAS_dec stereo 32 out.192 am1aa1s09.dec.wav ``` <!--- Below are labels that will be added but are not shown in description.
