Sample history
|
Shows the last 10 samples (BPM) and plots them on a graph.
The graph shows the average BPM as a blue vertical line. The
light blue region surrounding the blue line is a 'variance' zone.
Samples that fall within this zone are considered 'close enough'
and are represented by a gray bar. Samples that fall outside the
variance zone are represented by pink bars. Samples that are too
far out range for the graph to represent (over 300 BPM) are
represented by red bars.
A large number of pink bars means that the samples are not very
consistent in their timing. For more accurate readings you should
strive for a set of samples where the timing has remained consistent
for the sample duration.

Average BPM
|
The 'average' is the mean value of all the BPM values in the queue
after the highest and lowest value have been discarded. This helps
eliminate some common errors (such as a missed beat or an accidental
double-tap).
The average is only calculated after three or more samples are
collected in order to have enough data for a meaningful value
to be generated.
|
BPM/2
|
Shows the value of the BPM divided by two, in case you are tapping twice
for each beat.
|
BPM*2
|
Shows the value of the BPM multiplied by two, in case you are tapping on
every other beat.

Notes:
It is best to try to keep sampling until you get a run
where all your samples fall in (or very near) the blue vertical bar.
If you do, you can be pretty sure the average BPM value displayed is
accurate.
This page can't actually hear your music, so it is assuming you are actually
tapping on the beat. If you don't have any rhythm then your numbers
are likely wildly inaccurate ... sorry. :)
