This has been posted today on some news aggregators, but for those of
you who may have not seen it, here it is:
Sometime in the last 10 or 20 years, rock drumming has changed. Many
drummers will now don headphones in the studio (and sometimes even for
live performances) and synchronize their playing to an electronic
metronome - the click track. This allows for easier digital editing of
the recording. Since all of the measures are of equal duration, it is
easy to move measures or phrases around without worry that the timing
may be off. The click track has a down side - some say that songs
recorded against a click track sound sterile, that the missing tempo
deviations added life to a song.
I’ve always been curious about which drummers use a click track and
which don’t, so I thought it might be fun to try to build a click track
detector using the Echo Nest remix SDK ( remix is a Python library that
allows you to analyze and manipulate music).
