I always liked that transmission andthought there was something to it. It sounds decayed but it sounds like there was something there.

The Cassini spacecraft began detecting these radio emissions in April 2002, when Cassini was 374 million kilometers (234 million miles) from the planet, using the Cassini radio and plasma wave science instrument. The radio and plasma wave instrument has now provided the first high resolution observations of these emissions, showing an amazing array of variations in frequency and time. The complex radio spectrum with rising and falling tones, is very similar to Earth's auroral radio emissions. These structures indicate that there are numerous small radio sources moving along magnetic field lines threading the auroral region.
...spectrogram editing and synthesis capabilities, making use of unique spectrograph, synthesis and filtering algorithms developed specifically to achieve the best results possible. Photosounder turns sound processing problems into image processing challenges, and brings the power and flexibility of familiar image processing tools to the creation and transformation of sounds.
