During EEG acquisition with audio cues (e.g., the word "Water" spoken every 2 seconds), the audio protocol and EEG data writing operate on independent timing mechanisms. The audio is triggered via a background thread using time.sleep() between repetitions, while EEG data is segmented based on buffer length and assumed alignment with a fixed 2-second window. However, there is no shared time reference or event-based triggering between the two processes.
