The simplest music file to transcribe is a single note. Here I use a bassoon playing a single note A (octave 2) to walk through the simplest transcription.
From the signal and FFT result we can see that this is indeed a single note with a single dominant frequency.
The spectrogram confirms the simplicity of this example.
To transcribe this note we will use the built in bassoon profile and the default options (i.e. correlation).
The result is as expected.
Alternatively we could have elected to use the built in Convolutional Neural Network for the bassoon.
The result is a little different. The note ends just after the forth beat. The CNN transcribes this as a 3 beat note, not 4 beats.
