Bug description

It seems that there are some chirp artifacts in rendered output of MASA when coded on bitrate 384 kbps. This is not present in the EXT output transports and not on other bitrates. The probable cause is metadata coding. Output mode, and thus selected renderer does not change the effect.

Ways to reproduce

Encode and decode MASA (e.g., to binaural) using the specific sample. This sample cannot be shared due to music with no right to share. The content is music in left and speech in right.
