Turn your phone or tablet into a fantastic audio viewer. Easy to use and customize. Choose from several preset settings of incredible colors or create your own. CAVA is a bar spectrum audio viewer based on my own open source project with the same name. Take the audio from the device's microphone and visualize the amplitude of the different frequencies as bars on the screen. Each bar represents a certain bandwidth of low to high frequencies. The leftmost bar starts at 50 Hz and the rightmost bar ends at 10 kHz. Although the frequencies outside this spectrum are audible, they do not contribute much to the overall sound image. You can also adjust the number of bars.
