# Basic info <!--- Add commit SHA used to reproduce --> - Float reference: - Encoder (float):e15ad0ad - Decoder (float): - Fixed point: - Encoder (fixed): ff4d7358 - Decoder (fixed): # Bug description When forcing IVAS to GSC and analysing the output of the GSC module, it was observed that the fixed point pitch was often too low and the energy of the time domain excitation was not consistent with the floating point The figure below compares the excitation after the module enc_pit_exc_ivas() when GSC_IVAS_mode is forced to 1. When looking at the spectrum (last plot) it is possible to observe the energy mismatch between float and fixed excitation. {width=2148 height=1020} That is not a major correction as these modes are rarely used, and the frequency domain is compensating the energy. but it forces the GSC frequency domain to use only a part of it gain quantizer. # Ways to reproduce Box folder: ...\Box_EXTERNAL_IVAS_BASOP_VERIFICATION\issues\issue-xxxx <!-- Commandline or script --> ```bash -stereo -force GSC 16400 48 C:\Temp\dp03a4s03.wav bit (could be any file) ``` <!--- Below are labels that will be added but are not shown in description.
