Blind testing a 10c Pitch Difference (Sawtooth version)
How good are you at spotting pitch (frequency) differences?
Files being tested
|10c Up [saw]
||10c Down [saw]
||440Hz Flat [saw]
The first audio file plays back a 440Hz sine tone characterized by a
sudden increase in pitch occuring after 1s (10cent in this case). The second file introduces a decrease in
pitch by the same amount. The third one is flat.
The presence of harmonics in the sawtooth tone makes this test easier
than our original test. To go back to our original sine tone test, click here
For best results, please use headphones to
perform this test. Avoid using multiple speakers (a single speaker is OK) as the relative phase between the
speakers will introduce frequency-dependent level changes. These changes in perceived loudness may help you to spot
inaudible frequency changes.
For each column, tick the appropriate radio button. When you have labeled all 10 files, click the "Submit" button to obtain your score.

If you didn't pass this test with a score equal to 9 or higher,
you possibly reached the limit of your hearing.
