Hi, I noticed that the wav outputs of your program and HCADecoder have different spectrograms compared to [libcgss](https://github.com/hozuki/libcgss/) and [DereTore](https://github.com/OpenCGSS/DereTore). HCADecoder and CriTools output  libcgss and DereTore output  Do you have an idea of what caused this difference?
