Is it possible to recognize music by microphone?

Postby Chester Cheng » Wed Sep 04, 2002 12:05 pm

Hi all,
I know that we can recognize music notation by scanner, but I think this is not efficient. So I have an idea to use microphone to receive the signal of the musical instrument, then recognize it and translate into musicxml file.
But I know that the sound has contructive and destructive interference,
so I want to ask,
is it possible to recognize the mixed up signals? Thanks, Best Regards,

Automatic music transcription is a hard task - arguably as hard or harder the speech understanding. It is surprisingly difficult even to extract the fundamental frequency of notes from single note music.

There are, however, a goodly number of programs on the market which will recognise monophonic music quite accurately (so I'm led to believe - not really tried them out). An example (chosen randomly because if happens to be in my favourites) is http://www.digital-ear.com/info.htm. A useful link is

However, polyphonic recognisers are still very much in the labs, though some commercial products exist, they are not particularly effective.

If you are interested in the research, then contact me off-mail and I'll send you some useful links. The classic book in this area is 'Auditory Scene Analysis' - the name 'Bergmann' comes to mind as the author, but the title is definitely correct.
