Sonance - プロフェッショナルなオーディオビジュアライゼーションでビートをすべて見る

Sonance - A music player, an audio spectrum analyzer, and a decibel meter. Sonance plays music that is on your device, and displays waveform and audio spectrum visualizations, plus power level meters. You can see the beat ! Sonance has an in-car user interface, with large buttons, and swipe gestures to move between songs. It's good to use while driving, since you don't have to focus much on it to make a desired change, yet it also has entertaining visualizations to enhance the musical experience, when you can focus on it. Sonance has an easy to use shuffle mode, as well as the ability to repeat one, or a queue of chosen songs. It has a variety of settings allowing personal customization of startup, user interface, and visualizer settings. The visualizer has a full screen mode, that allows for all manner of customization, via pinch and swipe gestures. Sonance also works well with AirPlay, and the visualizers look great when Mirroring your device. Sonance also has the ability to visualize input from the microphone. This allows you to have fun with sound ! It analyzes sound from the built in microphone, or from an attached external microphone, and displays both the audio input signal, and the "frequency bars", which are the results of the spectrum analysis. The audio input signal is displayed in the lower view as a waveform and the spectrum is displayed in the upper view as bars indicating the strength of that frequency within the audio input signal. Frequencies range from 0 hertz to 24000 Hertz or 24K, this is the range of the iPhone and iPad microphone, and also the general range of human hearing. The decibel meter shows audio levels in two metrics. Recorded audio levels are shown as dB FS ( Full Scale ), -120 db to 0 db. Where 0 db is the highest possible level. For audio levels from the microphone or line-in device, the levels are shown as dB SPL ( Sound Pressure Level ), 0 db to 100 db. 120 db can cause pain, 140 db can cause damage. You can use a horizontal and vertical pinches on either display to zoom in/out of the visualization. On the Spectrum display you can also use a slide gesture, to move the display left and right, allowing you to see specific frequencies in detail. Pinches are cumulative, so keep pinching. The settings panel allows you to reset the app to default settings, so have fun exploring sound !
