The global electromagnetic resonance phenomenon is named after physicist Winfried Otto Schumann who predicted it mathematically in 1952. Schumann resonances are the principal background in the part of the electromagnetic spectrum [2] from 3 Hz through 60 Hz [3] and appear as distinct peaks at extremely low frequencies around 7.83 Hz (fundamental), 14.3, 20.8, 27.3, and 33.8 Hz.
The fundamental Schumann resonance is at approximately 7.83 Hz, the frequency at which the wavelength equals the circumference of the Earth, and higher harmonics occur at 14.1, 20.3, 26.4, and 32.4 Hz, etc. Lightning strikes excite these resonances, causing the Earth–ionosphere cavity to "ring" like a bell, resulting in a peak in the noise ...
Some of the features of SMPlayer are: holding a memory of the time position of each file it has played, audio/video filters and equalizer, variable speed playback (it also allows for frame-by-frame playback, forwards or backwards), configurable subtitles with Internet fetch, YouTube & Radio & TV [7] support with playback of up to 4K resolution at 60 fps, [8] skinnable user interface, automatic ...

Winfried Otto Schumann (May 20, 1888 – September 22, 1974) was a German physicist and electrical engineer who predicted the Schumann resonances, a series of low-frequency resonances caused by lightning discharges in the atmosphere.
Clementine v1.2, an audio player with a media library and online radio. The basic feature set of media players are a seek bar, a timer with the current and total playback time, playback controls (play, pause, previous, next, stop), playlists, a "repeat" mode, and a "shuffle" (or "random") mode for curiosity and to facilitate searching long timelines of files.
Spectrograph mode can be used to display room resonances: pink noise is applied to the room's sound system, and the signal from a test microphone in the room is displayed on Smaart. When the pink noise is muted, the display shows the lingering tails of noise frequencies that are resonating. [8]
The following comparison of video players compares general and technical information for notable software media player programs. For the purpose of this comparison, video players are defined as any media player which can play video , even if it can also play audio files.
