+As an alternative, `simulstream_score_quality` can be run without the `--audio-definition` specification, by using a list of 
+files as arguments of `--references` and `--transcripts`. In this case, the name of the files (trimmed of the extension)

+simulstream_score_quality --scorer comet \

+    --references AUDIO1.tgt,AUDIO2.tgt,AUDIO3.tgt \

 Lastly, ``simulstream_stats`` computes statistics like the computational cost and flickering ratio.
