FFT midi converter

I make this app free now and remove all ad, enjoy it! :)-------------------------------------------------------Convert sound from microphone or wav file to midi file! This means that you can convert the music sound into music notes now. It has real-time FFT frequency graph to detect frequency from microphone.If you have good ideas and suggestions please write in the review or email me. Thank you : )NOTE:-only support monophonic music (Polyphonic and harmonicity problems are very hard to solve)-only support wav 16-bit mono channel-max record time depends on memory of device-frequency resolution = (sample rate/FFT input size)-any parameter under graphic category will NOT affect midi generateTIPS:-double click to pause-use two fingers to adjust scale
