I am confident no one has been able to write code to read tells because we humans don’t know how we humans read tells.


Another example of it is how a human can listen to a French horn and a saxophone play a duet, then write out the score, even getting the key signature right.  Not on the first try of course, but I can do that if I can play it several times.  With all our sophisticated Fourier analysis and all our computer whiz-bangery, we are nowhere close to even that.  Reason: we don’t yet know how our minds can do that task.  But I can assure you, it can do it, and I can demonstrate it.




​>…Huh?  Whataya mean we don't know how players read tells?  I'll bet if you ask them they can explain just what Joe did that they read as a bluff and they were right.  Are you saying they just have vague feelings but don't know what they are basing them on?



The poker player can describe what Joe did, but there is no known way to turn that observation into code.



>…Also - what's the big deal about music transcription​?  I'll even bet that some of the really big music composition programs can be fed music and transcribe it into the score…

You can plug your MIDI controller into your computer, and as you play notes, the software will add notes to the sheet music, creating sheet music as you play.


​Or is this something different from what you are talking about?

Ja, different.  If you have a MIDI keyboard, the software can record what you played, or if you have a MIDI-equipped instrument such as an electric saxophone, the software can record what you played.  But that isn’t done by listening, it records key motion (and air pressure if it is an electric sax) like your computer does with the keyboard.


If you have a microphone attached to both instruments, software *might* be able to separate the two, or if you have a single instrument playing at a time, software can transcribe it.  But… a human can do what we still haven’t been able to do with software: listen to a French horn/sax duet a few times and figure out the score.


I chose those two instruments because they are generally in the same octave and it sounds cool if you get two good players doing a FH/sax duet.  Software might be able to extract the parts in a piccolo/Tuba duet (anyone know?)


A trained ear can transcribe either a sax solo or a French horn solo.  Put them together, the human can somehow tell which instrument is which from its unique timbre and work out who played what (not on the first try, or even the second.)  A machine is nowhere close to being able to do that I am told.  Or if so, it is a recent and very impressive development.
