A friend visited yesterday bearing an iPad on which an
application - i refuse to use the non-word 'app' - had been
loaded which recognises music. This works by holding the iPad
near a loudspeaker on which a song is being played and within
about 15 seconds the name of the song appears. We tested this
and got positive results for both artist and song with Bo
Diddley - playing the tune of the same name - and Lonnie
Donegan doing Rock Island Line. Metropolitan Klezmer - a
semi-pro band from NYC proved beyond its capacity.
I have no idea how this works but it suggests than
an application to recognise a fair proportion of bird calls
should be technically feasible. Ha anyone heard of such a
program being developed?
