# Bug description
Decoding the provided bitstream results in a high MLD of 57 for fixed point. Observing the output signals, a clear energy fluctuation for fixed point is evident w.r.t. float.
Float:
{width=540 height=506}
Fixed:
{width=540 height=506}

<!-- Commandline or script -->
```bash
./IVAS_dec -voip binaural_room_reverb 32 bit out.wav
```
The unmodified bitstream has also been uploaded. Decoding this only results in an MLD of 1.2, indicating an issue in the JBM path.
