Sound Check
This design is based on a digital VU meter for audio equipment, where the coloured bars are the low, mid and high frequency indicators from the EQ display or VU Meter. Hours (12) are the low bars on the left, 5 minute groups are in mid bars in the center and single minutes are the high bars on the right. Input indicators low and high show am/pm and the track number is the date, read as month and day.
