MIDI or WAV file to an array of frequencies and durations

Question

Is there a script / software / algorithm that allows you to convert a MIDI (or WAV) file to a list <frequency, duration>so that we can reproduce the "image" of this sound file, for example, through System.Console.Beep(frequency, duration)in C #?

Answer 1

You need to convert MIDI, WAV or another sound file to the original sound samples. Then, for consecutive blocks of samples (usually overlapping each block by 50%), use the window function (for example, Hanning), then FFT, then take the value of the FFT outputs, and then for audio you usually take 20 * log10 from this value to get the dB value .
