# Bug description
Using external renderer from OMASA to MASA2 output has (in addition to metadata issues already reported) severe distortions in the output transport audio signal.
This distortion is observed both in current `main` and MR !1743 fixing other distortions.
Example comparison of float vs basop outputs:
