【實用音樂app】Frequency Spectrum|最夯免費app

This is a free frequency spectrum that I have developed for my music app. I used it to test on my keyboard and get very accurate reading. Place your finger on the spectrum to get the respective frequency. It has an accuracy of +/- 5 Hz.

It has an auto peak detection on the graph in red dot and the maximum frequency value to top right.
