Sound You Can See !
Sonance is an Audio Spectrum Analyzer & Spectrograph App, and a Music Player. It analyzes sound from the Internal Mic, Line-In Input, USB devices or iTunes library songs, and displays the results in three separate views. The music player plays songs from the local iTunes library.
NOTE: iTunes Library songs must be located in /Users/'username'/Music directory. This is an Apple Mac App Store limitation.
The waveform view displays the raw input signal as a continuous wavy line, where each wave is a pulse of sound.
The spectrum view displays the frequency distribution as vertical bars, each bar represents a group of frequencies, the height indicating the strength of those frequencies within the audio signal.
The spectrogram view displays a two dimensional view of audio spectrum frequencies, over time. Each pixel represents a group of frequencies, it's color indicates the strength of those frequencies. The vertical rows represent different frequencies, and the horizontal columns represent time.

Frequencies range from 0 hertz to 48000 Hertz or 48K, this is half the sample rate of 96000 audio samples per second of a macbook pro internal microphone maximum sample rate. The display frequencies are half of the input device sample rate, which can be 44100, 48000, 88200, or 96000 samples per second. For music played via the music player, it depends on the rate contained within each song, most are in a range from 0 to 22050 Hertz, or half the 44100 samples per second used in compac disc recordings.
Since it also uses the microphone, any sound the mic can pick up is analyzed and displayed, so you can play music on your computer, or use a different sound system and see the frequency distribution, spectral density, and waveform.
In the Waveform View, you can adjust the Input Gain ( waveform height ), Display Width on the fly, and freeze the display.
The horizontal scale represents time in seconds. The vertical scale shows the audio sample value. For the 32-bit floating point audio codec, values range from -1.0 to 1.0. Voltage or power units are lost during conversion to the digital format.

Input levels differ greatly between recorded audio, and the microphone. Sonance has independant settings for both modes, and will switch automatically. This affects Input Gain on the waveform view, vMag on the spectrum view, and sensitivity on the spectrograph view.
