Music transcription allows to convert an audio recording to musical
notation through mathematical analysis. In the talk we will focus on
transcribing a monophonic audio input and see how we can modify it on
the fly. To achieve that, we need to determine pitch and duration of
each note, and then use these parameters to create a sequence of MIDI
events.

Music transcription allows to convert an audio recording to musical
notation through mathematical analysis. It is a very complex problem,
especially for polyphonic music - currently existing solutions yield
results with approx. 70% or less accuracy.

In the talk we will focus on transcribing a monophonic audio input and
see how we can modify it on the fly.
To achieve that, we need to determine pitch and duration of each note,
and then use these parameters to create a sequence of MIDI events.
MIDI stands for _Musical Instrument Digital Interface_ and it encodes
commands used to generate sounds by musical hardware or software.

Let's see how to play around with sounds using Python and a handful of
its powerful libraries. And let's do it in real-time!
