Abstract:
Video comparing the GW150914 and GW250114 spectrograms and audio clips.

Audio data is bandpassed and notched to allow the change in the detector sensitivity to be apparent. The video first plays both signals as recorded in the detectors, then plays both signals with a 30% increase in pitch to make it easier to recognize the chirp. Video inspired by a similar graphic at the GW1501914 press announcement.

Stills from the video showing the full spectrograms of GW150914 and GW250114 are also included as separate PDF files.
The individual audio files are also included as separate files.
