The figure shows panels of radio, optical, X-ray, and Gamma-ray light curves, waveforms of the sonification as a function of time, and spectrograms of the blazar Mrk 421. The light curves are available at: Download Light curves.
To ensure an accurate representation of the multiwavelength data and adhere to the established sonification research methodology, each frequency range must be analyzed independently. Simultaneous playback may lead to spectral masking and the loss of critical temporal features unique to each energy band. Users are therefore advised to utilize the individual playback controls to isolate each emission process, thereby preserving the scientific fidelity of the auditory mapping.
