Sonance is an audio spectrum analyzer and spectrograph app. It analyzes sound from the built in microphone or from the line-in input device, and displays the results in three separate views. 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.
