# Basic info <!--- Add commit SHA used to reproduce --> - Float reference: - Renderer (float): f40fa467 - Fixed point: - Renderer (fixed): ced61be13 # Bug description Using external renderer for rendering MASA2 input to, e.g., STEREO or BINAURAL results into severe audible "bubbling" artifacts. MLD is over 30 for both binaural and stereo outputs. FOA output has much lower MLD, but even that is over 10. Below is a waveform comparison clearly showing the artifacts in the difference signal  # Ways to reproduce Using LTV items. <!-- Commandline or script --> ```bash IVAS_rend -q -no_delay_cmp -if masa2 -i ivas-pc-testfiles/ltv48_MASA2TC.wav -fs 48 -im ivas-pc-testfiles/ltv48_MASA2TC.met -of STEREO -o 0014_ltv48_MASA2TC.wav_STEREO-no_delay_cmp.wav ``` <!--- Below are labels that will be added but are not shown in description.
