# Basic info <!--- Add commit SHA used to reproduce --> - Floating point: - Renderer (float): f40fa467 - Fixed point: - Renderer (fixed): bef2d70ce # Bug description External renderer MASA2 rendering to MONO or 5.1 output has significant differences compared to float renderer in frequency region above 12 kHz. Below is a spectrum from mono output, but 5.1 exhibits similar pattern. The differences are not visible in binaural output.  # Ways to reproduce Using STV. Commandline: ```bash IVAS_rend -if masa2 -i scripts/testv/stv1MASA2TC48c.wav -fs 48 -im scripts/testv/stv1MASA2TC48c.met -of MONO -o 0011_stv1MASA2TC48c.wav_MONO.wav ``` <!--- Below are labels that will be added but are not shown in description.
