Tapping Evaluation
• Long-term accuracy is very good
• Time quantization is not so great, but is OK
Timing from a windows console program
Timing from Sonic Visualiser
Console program time resolution about 4.644 ms
Sonic Visualiser time resolution 23.22 ms
• Local accuracy decreases by
40% (35 ms sd compared to 20 ms)
• Multiple tapping sessions
can remove quantization errors
